There's one spider in one dimension with no powers.
Actually, there's two!
One is called the "Human Spider" and she runs around in a Halloween Spider-man costume with a baseball bat stopping crime.
The other doesn't really go by a name, mainly because nobody's sure if they even exist!
They work in the shadows, but the only reason people know it's a spider person is the mumbling of the bad guys they've stopped...
Yeah, don't go visiting the second one's dimension, trust me.
Unamed spider is scarier than baseball bat spider.
