Bloodlust on for all sides
Fight on tokiros world
Thanos, rather easily. You're dealing with a guy who could casually KO Silver Surfer, give a Power Gem-enhanced Thor troubles in combat, can casually destroy planets with energy blasts, manipulate matter and is as ridiculous in prep as Dr. Doom and Batman.
thanos cannot casually ko silver surer
Actually, he did. In only a few blows during one confrontation they had, Thanos inflicted enough damage on Surfer where he incapacitated and nearly killed the former Herald of Galactus.
thor has a win on thanos
And that's impressive, how? Thanos has beaten Thor on multiple occasions, even among a small group of heroes capable of planet-busting physical blows. He's in a different league of attributes compared to heroes like Surfer and Thor.
Lulz the mad titan strikes again.
Thanos was a threat before he became the avatar of death. After he was banished from the realm of death and already had godly regen he was a gigantic threat. He got the Infinity gauntlet and could take on the multiverse and obtained the heart of the universe and erased everything.
Thanos is boss. He is truly a villain that actually accomplished his goal.
