Denki seems the most likely because of the released concept art for his original design. He's also a "Raijin" type. He may have no weakness and may be completely faking. Speedster, teleporter, flying Raijin, electric shock monster.
Teleports behind Uravity with electrifiied Katana, "Nothing Personnel." Ganks Deku's girl... she dies in his arms! No!
Alternatively, the traitor could be the principal, Nezu. He's a super genius and an animal. Might have switched sides because he has been treated like crap or wants to become human.
Thought this would be an interesting topic to make a thread for. They haven't touched on the traitor stuff lately in the series with everything going on with the new group of villains appearing, but wondering who the traitor is in UA I think is one of the more interesting sub-plots.
Obviously the traitor is someone that had to have been at the training camp, right? So it has to be one of the teachers there or one of the students in Class A or B. Right now it seems like a lot of the popular choices online have Mashirao Ojiro or Denki Kaminari being the traitor. Also if it is someone from Class B I think that Momoma might be an interesting option. He is one of the few Class B students that has gotten some focus, and his copying power would be very useful for someone who is trying to hide themselves being a traitor.
