Diablos from FF8 was weak as all hell, the only thing that hurt was that stupid spell that always did like 40% damage to your total hitpoints... (Can't fucking remember what the name is, now I'm pissed...)
Anything related to Diablo II in any form is gay as all hell, so I'm gonna give it to Diablos. Just because he was significantly cooler than any Diablo II-related drek.
Not a chance. Your just biased because you weren't a sucker like the rest of us that got sucked in for years... The Lightning and Fire attacks from Diablo are way too strong for Diablos. Diablo's skin is next to inpenetrable too.
Being a "badass" in the world of Diablo II isn't a character trait that particularly impresses me. That's like saying "I'm the smartest kid in my remedial ESL class!"
