More info about him in the comments

I'm going to say
gauge sounds cool

Black shadow

But dark shadow exists and it sounds too similar

Because it’s a motorcycle

Real name: Gabriel Simmons
Age: 16
Power: he has none, he uses his gadgets to do hero stuff

"Looking at him, you'd never guess he was a hero."

Sounds like batman

y e s

he is an emo Robin

also:

Sabo

eeehhhh.....

I found a good one, what do you think?

Yea, better

I said sabo bc that's my third favorite one piece character's name...he used to not have a devil fruit and relied on his pipe-sword and haki to fight enemies

cool

I chose somber because he emo and dark like Batman. The literal embodiment of current Deku's mood in the manga.

Also, this is at the start of the story, when he was still a vigilante fighting villains on his own. When he meets Lilith by joining a team of heroes, he changes his name to Ember (Lilith suggested the name. Yes, this is an Izuocha reference.)
