The Prowler first appeared in a two-part story found in Amazing Spider-Man #78 and 79. He has his supporters, but I've always found him rather whiny and uninteresting. He also wears green and purple, which just never works. Anyway, here's where he fusses and moans to Spidey after he gets caught.
"You've hurt no one"?
"You've stolen nothing"?
Ladies and gents, I give you Exhibit "A"....
Yup, when Spidey first laid eyes on the Prowler, he had stolen from the Daily Bugle and assaulted a security guard into unconsciousness. I'm pretty sure that counts as stealing and hurting someone.
Yes, you nerds, I realize that the Prowler was just temporarily stealing the money so he could recover it and look like a hero. I'm also aware that Spider-Man's appearance kept him from successfully leaving with it. You know what? It doesn't matter. The man committed a robbery, which is worse than just stealing something. YEESH!
So Spidey basically allows another criminal to run right past him, just like he did before he ever even became Spider-Man back in Amazing Fantasy #15. I expect more from my masked vigilantes, I do.
Here's my kind of protest, from Amazing #69:
Yeah! Make some frosting!
Bake a cake!
Eat it all!
Get a stomach ache!
I really don't know where I was going with that. I think I just wanted to show off my own mad protest skillz, y'all.
Hey! Random Bitch-Slap!(tm!):
Thanks, Amazing #70!
See you tomorrow!
