Corresponding with James Jesse
Taking up the mantle of The Trickster
In 2015, Axel began acting as a new version of The Trickster. He sent parachute bombs over a park in Central City, but no children were killed thanks to The Flash. He announced via a blog that The Trickster had re-emerged. The Trickster announced in another one, his plans to go bigger than the parachute bombings because he thought that, 'they deserved something much bigger.' He misled the public to believe that he had hidden a giant bomb to destroy the city so both the police and The Flash were distracted.
In the meantime, Axel helped James Jesse escape from prison, with Henry Allen as a hostage. They took him to a safehouse, where the two Tricksters discussed their plans. Asking why he'd been chosen, James revealed that he was Axel's father.
That night, they headed to an event held by Mayor Anthony Bellows, poisoning all of the guests by pretending to be waiters. In doing so, they were able to threaten the guests to electronically transfer all of their money to the two Tricksters. The Flash arrived, though he was given a bomb strapped to his wrist, connected to a speedometer. However, he was able to get rid of it and came back, giving everyone an antidote and stopping James and Axel. Afterwards, the duo was taken by Central City Police Department for incarceration. 
Brief return and arrested once again
Axel is seen questioning Barry how he killed Clifford Devoe. He eats a pudding that does not agree with him. It's revealed that's all part of a escape plan organized by his mother who wants the both of them to go the straight and narrow path. Axel however refuses her and wants to attain his father's attention by pulling off a big crime however that's unsuccessful so he is finally arrested along with his mother by Elongated Man and Vibe.
