We all know how EG suddenly becomes good after the MIBR knife incident. It opens a portal to an alternate dimension where EG are replaced by prime OPTIC. Ever since then EG with their newfound skill have began terrorising this timeline.
However, with something's knife kill, balance has been restored and the dimensional portal of where EG was replaced by OPTIC has been closed. Notice how they didn't win a single round after that knife kill, its because the old shit EG was returned.
It all make sense,, the villain getting random power up is an anime trope made for Tokyo, however the villain losing their power in a poetic manner is a superhero plot fit for LA.
