Bitten by a radioactive spider though a fiber that could blur light and refocus it like a camera lenses, that material and cells went into his skin, leaving nothing but floating clothes and an invisible man. To stay visible, he covers himself in his own web, but can retract it into his arm when he needs too. He doesn't need a machine to shoot his webs for him. Due to him being bit in his right hand, that hand's web is invisible, but he doesn't like using it because he would rather see his webs, he uses it in a different way, where he can get a strand, cover it in a match like synthetic, and then retract it. He can use this but balling up a bunch of web in his hand, rubbing the synthetic, and then shotgun his web forward

Besides that he's just like regular spiderman, if he was a scientist.

This was heavily inspired by H. G. Wells Invisible Man, but now a good guy!
