Well i could say ultimate hulk because he ripped adamantium in half..... or possibly hulk2099 because that dude is kick-ass..... but I'm going with Professor hulk.
Is there a reason you put Mindless last? I thought he was one of the most dangerous. And you also put Prof before Maestro. In Future Imperfect Maestro beats him up pretty good and breaks his neck.
I'd say
Maestro Hulk
Mindless Hulk
Savage Hulk
Professor Hulk / Gray Hulk
Well maybe you're right about Professor Hulk and Maestro Hulk, but I wouldn't consider Mindless Hulk that much of a threat compared to the other Hulks since he can't reason. If he can't reason then why consider him that much of a threat? It's not like he has an advantage over the other Hulks.
Proffessor Hulk isn't a bad choice if you think about it as he is the smartest here and would be smart wnough to let the other Hulks take care of eachother then take them when they are very weak.
I think his lack of reasoning is an advantage in some ways. Without having to think, he becomes enraged a lot more quickly, and we all know what happens when Hulk gets angry...
But that's the only advantage he has. It's not like he's stronger or more durable or anything like that. Savage Hulk is definitely a thread because he CAN reason and he reacts very quick to anger. Personally I think Savage Hulk could kick Mindless Hulk's ass quite easily. So can Professor Hulk or Gray Hulk.
Mindless Hulk GETS stronger faster than the other Hulks because he gets angrier quicker. That can be an advantage don't you think? I'd say that kinda balances out his inability to reason.. but maybe not enough.
Exactly. Not enough because he doesn't have the fighting skills of the other Hulks and the ability to think of different strategies to beat his oponent. The thing about him is that he only has animal instincts so that means that his only goal in a fight would be to survive. He probably wouldn't even stick around to fight. He would probably fun away just because he wants to survive.
It's supposed to be the evil side of Hulk that just wants to kill and destroy the world and get revenge on people. He has all the powers of Hulk and is supposed to have normal intelligence so he's a real threat.
