Nice to see a profile list for your characters. Definitely adds some nice info to the universe. Will you include the villains as well?

Nanites can only rearrange mass, not add to it. Either he weighs 289 pounds all the time, or 185 pounds all the time. That the nanite coccoon adds to his mass is silly.

If you want to make it pseudoscientifically accurate, say that the nanite coccoon has a molecular structure not acheivable except by nanotechnology, making it possible for it to be efective armor without the corresponding weight.

Outside of that, this series of profiles is a cool idea. Might you do one for your other superhero story, Den of Thieves?
