- —Grodd asking Barry to kill Solovar[src]
Grodd is a silverback gorilla that was experimented on by S.T.A.R. Labs, and is now currently the only known non-human meta-human, rather being known as a meta-gorilla. After being exposed to the energy from the particle accelerator, Grodd then escaped his cage and developed powerful psychic abilities, becoming a near-unstoppable enemy of the Flash. Having cared for Grodd, Caitlin Snow felt bad for his condition as the only meta-gorilla, and so helped Team Flash send him to Earth Two where he could be with more of his kind in Gorilla City. However, Grodd wanted to rule over humankind, plotting to dethrone Solovar and to take over Central City on Earth One with an army. After this failed, he was locked up back on Earth One by A.R.G.U.S.
Four years before the particle accelerator accident, Grodd was an ordinary silver back gorilla that was kept as a test subject in S.T.A.R. Labs. He was scheduled to be part of enhanced gene therapy experiments conducted by Harrison Wells and Wade Eiling, the latter of whom wanted to explore the possibilities of psychic abilities, such as mind control, torturing Grodd in a similar manner to that in which he tortured Martin Stein. However, once Wells discovered Eiling's inhumane methods, he shut down the program but decided on other plans for Grodd himself. Along with Wells, Caitlin also grew fond of Grodd and often visited him in his cage.
The S.T.A.R. Labs accident
When the S.T.A.R. Labs particle accelerator exploded, the dark matter it released activated the drugs and medicines Eiling and his men had administered to Grodd, awakening his psychic powers.
Living in the sewers and working with Wells
He took up residence in a sewer and began carving his own name into a wall repeatedly. He was encountered by workmen, who attempted to run but were attacked (and seemingly killed) by Grodd. Later, the Reverse-Flash abducted Wade Eiling and brought him to Grodd, revealing his identity as Harrison Wells. Grodd displayed telepathic powers, as Eiling could "hear" someone talking in his head and mentioned God. Grodd corrected him and said his own name before grabbed Eiling from behind and drag him away.
Three months later, after Wells is exposed as the Reverse-Flash, he sends Grodd to distract Barry Allen's team. To that end, Grodd mentally controls Eiling into attacking a gold reserve. As the Flash arrived on scene, Grodd, using Eiling as a conduit, incapacitated Barry by bombarding with mental hallucinations of Eiling's experiments on him, before having his puppet flee the scene. Grodd continued to control Eiling by attacking a police escort before he was captured by Barry and imprisoned in the S.T.A.R. Labs particle accelerator. Grodd communicated through Eiling, acknowledging Barry and Caitlin Snow by name.
Grodd later kidnapped Joe West when he, Barry and Cisco Ramon were searching the sewers for him. When Joe pulled out his gun, Grodd used his powers to make Joe point his gun at himself, but doesn't fire it while showing how he dislikes guns and bananas.
Later, Cisco and Caitlin force Grodd away from Joe by remotely venting steam pipes so he'd be far enough for Barry, who was protected against his telepathy with a headband, to hit him with a super sonic punch, but Grodd's sheer size and strength enabled him catch his fist and lift Barry into the air by the neck. As he tossed the Flash through a brick wall into a subway tunnel, the latter lost his headband, allowing Grodd to mentally attack him again, crippling him as an oncoming train was approaching. However, with help from Iris West's motivation, Barry obtained the will to overcome Grodd's attack and evaded the train. Grodd leaped at Barry, who dodged the attack, and the gorilla was hit by a second train. However, Grodd survived and made his way to the surface, climbing and jumping off a building, furious.
Departure to Earth Two
Grodd returns briefly, gathering various neuro-enhancing chemicals and kidnapping Caitlin under mind control in the hopes of forcing her to create more intelligent apes, however, he is stopped by the efforts of Barry, Cisco and Earth Two's Harrison Wells. They trick him into following Barry to the site of one of the breaches in Central City, and Barry manages to force him through, sending Grodd to a jungle on Earth Two, which is revealed by Dr. Wells to be the location of a refuge for gorillas who'd been subjected to lab experiments, like himself.
During his time in Gorilla City, Grodd was forced to serve Solovar, the leader of Gorilla City. He also seeked for revenge on Team Flash, thus, one year after he came to Gorilla City, Grodd came up with a plan of revenge: beat Solovar, become the leader of Gorilla City, return to Earth One and attack Central City with the help of the other gorillas. Knowing he can't beat Solovar, Grodd sent an invitation to Wells, asking him to come to Gorilla City. When Wells came with 10 other people, Grodd killed the 10 people and kidnapped Wells, knowing it will bring the attention of Team Flash, including Barry, who can beat Solovar.
The plan worked as Barry, Cisco, Caitlin and Julian Albert came to save Wells, only to get captured by Grodd and other gorillas. Grodd brought them to the city and locked them in cages, without informing Solovar. After they woke up, Grodd, controlling Wells, told the team about Solovar, and that he wants to rule the humans and bring a war to Earth One (In reality, Grodd wanted Barry to kill Solovar so he could be the leader of Gorilla City), and that Barry is going to be sent to the arena and fight Solovar until one of them die. Grodd also told them that if Solovar will lose, he will become the leader of Gorilla City, and he will keep the gorillas in the city. When Barry asked him how they can trust him, Grodd said that Earth One is still his home, and there are still humans that he will never forget, referring to Caitlin. He then stopped controlling Wells and came to the room, telling Barry that if he will win, Central City will be spared, but if he won't, Central City will be destroyed. Later, Grodd came to the room with Solovar, who was mad that Grodd didn't tell him that humans came to the city. As Grodd began to explain to Solovar that he was going to inform him, Solover punched Grodd in the face, making him fall to the ground. After Solovar explained the situation to Team Flash, the two gorillas left, leaving the team in their cells. Grodd later watched the fight between The Flash and Solovar. After Barry won and told the gorillas that the humans only want peace, Grodd demanded for Flash to be taken out. Barry was shot by a dart, which made him pass out.
After that, Grodd, controlling Wells, told Barry that now he is the ruler of Gorilla City and he is not going to let them go. After Barry realized Grodd lied to them and that Solovar didn't want to attack Central City; he does, Grodd told them how he came up with the idea. Cisco then asked him why he doesn't kill them. Grodd told him that he needs him to open a breach to Earth One so he and his army could go there. When Barry told him that he cannot do this, Grodd replied by saying that he is an animal. Barry threatened Grodd that he is going to stop him, before Grodd stopped controlling Wells and came to the room, replying that he won't stop him. When Grodd came to check the team, he found Barry, lying on the ground, frozen. Caitlin told Grodd that Barry went into shock and his heart stopped. He then checked Barry, saying that he is cold. Caitlin said that he is dead (In reality, Caitlin used her cold powers, which Grodd didn't know she had them, to freeze Barry and trick Grodd). Grodd told her that he has no use for him anyway, before dragging "the body" out of the cell. Later, he caught Team Flash trying to escape. As the Gorillas tried to stop them, the team went into a breach to Earth One, escaping Grodd. After they left, Grodd roared in anger. Afterward, Grodd got Gypsy, planning to use her to open a breach to Earth One. He told her that she is going to open the breach, and Central City is going to fall before him.
Grodd led his army to Earth One and then sent Gypsy to attack Team Flash. After failing to bring a missile to Central City, he led his army into the streets, only to be faced by Barry, Kid Flash, and Jesse Quick. After a brief battle, in which the gorillas appeared to be succeeding against the speedsters, Gypsy and Cisco appeared with Solovar, who was armed and dressed in golden battle armor. In his vengeful fury, Solovar brutally battled Grodd. After throwing a few punches, Solovar was able to overpower Grodd and defeat him. Before he could finish him off, Barry stopped him and asked him to spare Grodd like Barry spared Solovar. He agreed on the condition that Grodd was never to return to Earth Two and departed with the army of gorillas that now bowed to him. Grodd was then incarcerated on Earth One by A.R.G.U.S..
Not much of Grodd's personality is shown due to his developing psychic powers, though he has demonstrated a high level of intelligence. Grodd's intelligence seems to be increasing with time as his ability to form full sentences and communicate increases with each appearance he makes. Originally, Grodd would speak in third person and often only use 2-3 word sentences but, by the time of "attack on gorilla city", Grodd spoke fluent English through Harry. He also has some contempt towards humans, shown when he battles Barry a second time while psychically attacking him, stating "human weak". This indicates that he views humans are inferior to him. In addition, he despises Eiling greatly due to his experiments, and was not hesitant in manipulating him to commit crimes and take the chance to hurt him. The only person he has not shown to hate is Eobard Thawne, who saved him from Eiling's experiments. As such, he views him as a father, and will presumably comply to any request Eobard will ask him for. He also does not hate Caitlin Snow, stating while controlling her "Caitlin good". The reason behind this is currently unknown but it can be assumed it's because as Cisco said, "she was always kind to him".
Grodd's contempt for humans may be what drives his sadism towards them, as shown when he forced Joe to point a gun at his own head while leaving the man total awareness of what was happening to him. He is also lonely and wants more like him, which is part of the reason that drives him to kill and even steal Caitlin and make her make more of him. Grodd had a strong bond with Eobard, calling him father, and was easily able to tell Harrison Wells from Earth Two was not him before being fooled into thinking he was Eobard. Eobard soon taught Grodd to always think ahead, a trait he continues to use even after his death. Grodd lives under one code: Kill Or Be Killed.
Ironically, despite being an ape, Grodd does not like bananas.
Powers and abilities
- Meta-gorilla physiology/Psychic serums enhancements: After Grodd was struck by the energy of the Particle Accelerator explosion but also due to all the drugs Eiling and Wells injected him with, this altered his DNA and supercharged his cells, augmenting his physiology into well-beyond normal gorilla condition.
- Super agility: Grodd can scale a building and maneuver through sewers despite his large size with minimal effort. He can also move fairly quickly for his size. He was able to catch up with the Flash, when he was goaded to chase him.
- Super durability: Grodd is durable enough to survive getting hit by a train as well as take several super speed enhanced physical attacks from Barry unfazed, showing himself even more resilient than Tony Woodward's metallic form. However, with enough velocity behind his strikes, Barry can inflict some damage on him.
- Super strength: Due to his unusually large size and modifications, Grodd has shown considerably high strength, far more than any other gorilla. With a single hand, he is able to easily lift a full-grown adult human male. As Barry attempted to perform a super sonic punch on Grodd, Grodd caught Barry's fist with relative ease and hurled him aside. His strikes can send people flying great distances in the air, with enough force to make an impact with another surface fatal. Yet despite his mighty strength he was not strong enough to defeat Solovar.
- Telepathy: With the power to send neurological signals beyond himself and into others, Grodd gained mental-manipulation powers. Grodd most commonly uses this as a means to talk to others. This can also allow him to sense when people are near, quickly alerting him of the Flash running at him at Mach 1 speed. He can also control humans that are near him like puppets and maintain the control for prolonged periods of time. For offensive purposes, Grodd can overwhelm the minds of his enemies with his own negative memories and severely disorient and cripple them. Such attacks also can be projected via those under mind-control. Likewise, he is able to link his mind with the puppet's, allowing him to see and hear what they do. It would appear that his range of influence is only on what he can physically perceive through his senses. Those who have been continually exposed to Grodd's power appear to develop a lasting physic bond with him. Grodd can also control someone's actions while leaving them conscious as he did with Joe. He kidnapped Caitlin over mind control and when Cisco was talking to Caitlin, she punches him under Grodd's control. He can also mentally attack through the victim's own negative and traumatizing memories, as he did to Flash to make him see and feel Grodd's memories of being experimented on as if he were experiencing it himself. Barry managed to use his memories of Iris to counter this and continue to fight.
- High-level intellect/Expert tactician: Grodd's most noticeable and dangerous trait is his high intellect, making him a threat even to humanity and other metahumans like the Flash. In 2015, after escaping Star Labs he went and lived in the sewers and started making math equations on the walls of his sewer home, Grodd's intelligence is rapidly expanding. Said intellect include changing the direction of Barry's sonic punch. Very calculating and methodical in every action he takes. He is able to plan for every plausible detail several steps ahead, a trait he learned from Eobard. By 2017, he was able to construct a plan in which helped him take control of Gorilla City and all of his other fellow Gorilla-kind.
- Multilingual: Although he was using his telepathy, it can be assumed that Grodd is capable of fluently speaking English and animal languages. By 2017, he began speaking English fluently, through telepathy.
Behind the scenes
- In the DC comics, Gorilla Grodd obtained his heightened intellect, telepathy and telekinesis after being exposed to the radiation of a meteorite. This same meteor also enhanced an entire troupe of gorillas which went off to create Gorilla City.
- Grodd's ironic dislike of bananas is a trait shared by his counterpart from the animated series, Justice League/Justice League Unlimited.
- The yellow helmet Grodd had Eiling wear is likely a reference to the DCAU Grodd's mind control helmet.
- Like in the DC comics, Grodd takes control of Gorilla City in the heart of an African jungle, though it was on Earth One in the comics.
- When Cisco is talking about how Grodd could be an intelligent ape mad at humanity, he is referencing Conquest of the Planet of the Apes.
