Okay, here's my opinion. I dont think Carnage belongs on that list. I may be a Carnage fan, but I can definately see the Bias in putting him on the list. Even though I am not exactly a Morlun fan, I dont think he should be on there either, or at least not that high. I also believe Angelo Fortunato Venom deserves a spot if Gargan is on there. Speaking of which, Gargan should have at least been in the top ten.
It's not all about power it's how much they suck or how bad there histories and personality's are, or if they are really needed or just a filler, power is only one segment that should be focused on, the walrus is designed for a laugh, consider the appalling villains of BND who are supposed to reinvent the Spider-Man world, they are cliched and boring with nothing new or original added to there mix, Gargan is a whining wreck, who keeps saying, i don't like the symbiote, and who can't use it correctly or efficiently, also it must be noted that Venom Gargans design is awful to look at.
