I don't get why you guys think Thanos is written as some super powerful being in the comics.
He jobbed to Kitty Pride in that one Guardians by Bendis and then he jobbed to a device built by Blue Marvel and T'Challa.
IIRC
-He also threw down with Odin who has destroyed galaxies
-Destroyed a planet just by fighting near it
-Has telepathic capabilities great enough to disregard telepaths around Professor X's level
-Gone through dimensions that have the laws of physics no longer apply to the point where he was melting/turning into -glass and then regenerated/toughed them out because of willpower/molecular control
-Was unscathed by dedicated assault by Silver Surfer who can pretty easily blow up planets and has Flash type speed
-Consistently was a threat to the whole Marvel universe not because of any of the above specifically but because he was smart enough to come up with plans to get power like the Infinity Gauntlet
-Was a key role as an avatar of Death in ending a universe of corrupted/rampant life
But like someone said, maybe that's the Thanos before the one we have now *shrug*
Also one time the cops arrested him, but that can happen to anyone
