I feel like I'm arguing with a 12 year old. I'm not going to face nothing from someone who can't even get a straight argument. This is you "Kraven is lame dude...cuz he uh he looks lame! Yea and uh....yea hes like yea lame!"
You don't see what is exciting about Kraven? Go read Kraven's Last Hunt, one of the best Spider-Man stories ever.
I don't know what ultimate comics you've been reading, but Ultimate Electro is not a colleague of Peter.
lol wait wait, this is one of your reasonings? Kraven is superhuman, so he can go toe toe with Spider-Man in a physical fight. He has enhanced sight, smell, and hearing, so once he fights Spider-Man, he can track him down anywhere, which can be troubles for Peter and his friends. Not only added with his experienced hunting skills, he has a vast array of weaponry at his disposal and can set up a multitude of traps for Spidey. Hmm from stating all that, I can imagine a ton of interesting and exciting fight sequences. Hmm is your imagination that lacking?
