- "I’m the queen of this hive"
- —Brie Larvan to Felicity Smoak[src]
Working at Mercury Labs
Brie once worked at Mercury Labs, developing robotic bees for agricultural purposes. However, she continued to develop them for military-grade application, leading to Lindsay Kang and Bill Carlisle reporting her to their boss, Tina McGee. For this, she was fired.
Targeting her former co-workers
Growing bitter from being fired, Brie began to go after her former co-workers. She sent her bees remotely after Lindsay Kang and then Bill Carlisle, killing them both by injecting copious amounts of apitoxin. She was almost thwarted by The Flash and his team, but the bees stung The Flash, nearly killing him. Brie sent her bees after Tina McGee, but before long she was located by the S.T.A.R. Labs team, who sent The Flash. She sent some bees to swarm him but was fought for control by Felicity Smoak. In the end, Felicity was able to both turn them off, as well as redirect the bees directed at Dr. McGee, in turn short-circuiting them. She was ultimately captured by the Flash.
Taking Palmer Tech hostage
Shortly after being imprisoned at Iron Heights Prison, Brie Larvan learned that a tumor was attached to her spine and the surgery to remove it would cost her the use of her legs. Not wanting this outcome and learning about the technology used by Felicity Smoak to walk again, Brie Larvan hacked prison records to change her release date to March 29, 2016. Brie then reactivated and added upgrading software to her bees. She then went to Palmer Tech and took its Board of Directors hostage killing a member in the process, demanding to know where Felicity is. She then sent a message throughout the building demanding Felicity to surrender herself in 10 minutes or she would start killing Board members. After several minutes of her bees chasing Felicity, Thea, and Donna, the Green Arrow, Black Canary and Spartan showed up. They attempted to get through but were stopped by Brie's bees resulting in the Green Arrow getting stung and forcing Brie to add another 5 minutes to her demands due to the sudden appearance of the Green Arrow. After Felicity and Thea rescued the board members, Brie then proceeded to take them hostage. Trying to stall for time, Felicity gave Brie access to the lab where the designs for the spinal chip was held. However, after getting the designs Brie recognized the code as something similar to the code used by the hacker that sent her to jail. Wanting to get revenge for her imprisonment, Brie went back to Felicity's office to kill her. Before she could kill Felicity the Green Arrow burst into the room having recovered from their earlier encounter. The Green Arrow then fired an arrow at her bees which held a virus developed by Curtis Holt. Her bees were then shut down by Curtis. She then shot the Green Arrow with her gun and soon began to threaten everybody in the room. Curtis, however, reactivated the bees himself which then proceeded to sting her multiple times causing her to fall into a coma. SCPD then picked up her up and took her to Starling General Hospital to be treated.
The zealous scientific mind Brie Larvan possessed is only matched by her ambition and vengefulness. Originally designing robotic bees for agriculture and defence she became obsessed with designing them for military purposes - not realising the destructive potential for such an endeavour caused her to believe her co-workers whistleblowing and superior firing her was an act of betrayal that caused them to deserve their death. However, Larvan is also concerned with her welfare and being though her lack of morals make her actions in this regard more extreme, such as not wanting to be paralysed from a surgery to save her life so badly that she was willing to murder an entire board of innocent victims to achieve Felicty Smoak’s technology.
Larvan has a deep affinity for bees and their paraphernalia. From designing miniature robotic bees and outfitting her lair with hive designs, Larvan also dressed accordingly with colours such as yellow and honeycomb patterns.
Despite her cold and bitter nature, Larvan is not without a sense of humour particularly those that concern bees such as asking Tina McGee if she could be “buzzed” in and describing her vengeance to Barry Allen as a “sting of betrayal“. During her siege of Palmer Industries, she continuously enunciated “be” in the words of her sentences. With or without this humorous edge, Larvan does not shy from brutal means to obtain revenge such as suffocating Carlisle with her bees and stinging Kang to death for telling on her. Though brilliant, her vengeful and arrogant nature are more prevailant such as defying The Flash despite her lack of powers which caused her to be easily restrained when her bees were deactivated and going to excessive lengths to murder Felicty Smoak despite having already obtained the technology required to treat her.
- Genius-level intellect: Brie is very intelligent, as it took her years to develop robotic bees.
- Computer specialist/Master computer hacker: Brie is a highly skilled computer specialist and hacker, she was able to hack into the computers from S.T.A.R. Labs, and cause one of the computers to explode. Her computer specialist and hacking skills are at Felicity Smoak's level.
- Robotic bees: Brie created robotic bees for agricultural use. However, she later designed them for military use, with the venom in each their stingers powerful enough to kill a full-grown elephant.
- In the DC comics, Bug-Eyed Bandit is a villain of The Atom, but is, in fact, a male named Bertram Larvan.
- Cisco initially planned on naming Brie as "Queen Bee". In the DC comics, Queen Bee has been a name shared by four super-villains, two of which are extraterrestrials who rule over an insect planet, while the other two are human queens of the fictional nation of Bialya. Some incarnations have been associated with H.I.V.E. and were known under the alias of the H.I.V.E. Queen.
