With so many spider like qualities AND the word "web" in his actual name, it was surprising how few limbs he actually had! As an expert infiltrator and spy, I thought he should have quieter tools than a metal grappling hook and a gun, so now he can shoot webs "spiderman style" AND fashion them into crude weapons if he needs to (the webs into weapons idea came from a Naruto villain called Kidomaru - although he used to puke it...).
