Did you know that Thanos and Thor teamed up in Peter David's run on Captain Marvel and Jim Starlin's Infinity Finale?
That's another reason i don't like Thuggish Thanos, they are trying too hard to make him 'evil' when he wasnt really pure evil under Starlin as such he thought in terms and ideas much bigger and grandiose then the individual could imagine which makes his killings hard to understand, but he was all about yhe bigger universal picture and perfectly willing to occasionally team up with the heroes to save the universe. Kind of like Kain from Legacy of Kain. (does that mean Adam Warlock is Raziel? LOL)
