Because of you i just spent the last half an hour looking up Blue Beetle redesigns for inspiration since i can't be asked to go with regular Jaime...

[hider=Ideas]
[list]
[*]Essentially young genius teenage boy turned vigilante Ted Kord or Jaime Reyes, with him creating his own tech, etc.

[*]Same idea, but with tech more akin to scarab armour. Maybe even redesigned as a hero named Red Ant (with the possibility of shrinking, idk)

[*]Sorcery or something. Tattoos glow in a similar manner to Aang when using powers.

[*]Ward of Doctor Fate, Khalid Nassour is a recently orphaned young man who recently discovered his latent magical abilities. Door to his room in the tower will essentially be a magical doorway to the Tower of Fate.
[*]Young teenage genius creates shrinking tech. Young teenage genius neglects to create a way of unshrinking himself.
