For fun. Imagine if you lived in a superhero-populated world, and what codename you would have if you were a superhero yourself (or supervillain). One user says the powers/abilities/skills you have, then you come up with the codename you would make if it really happened, possibly explaining why, then they come up with the powers/abilities/skills.
Only rule I have for now: Try to avoid super famous codenames, mainly by the big two. Please don't say "Iron Man" if someone suggests you have an armored suit, that's just boring.
User 1: Shadow Manipulation: You can blend in with the night, manipulate shadows, solidify them to use a weapons, and use them as a means to teleport.
User 2: Shade Stalker. Seems fitting for someone who blends in with the shadows.
I'll get this started:
Time Manipulation: You can't time travel, but you can zoom forward, backward, freeze time within an area, create "time shields" to deflect shots, and time blasts for offensive uses.
