1 Xavier/Jean/Moondragon- Mind-thanos is far superior
2 Gilamesh/Juggernaut/Merged Hulk- Strength & Durability-could match them all adequately
3 Reed/Banner/Doom/High Evolutionary- Intelligence & Tactics/Strategy-superior to them all
4 Vulcan/SS/Maikail Rasputin- Energy Manipulating-thanos stomps them
5 Circe/SS/Molecule Man- Matter Manipulating-molecule man shits all over thanos in this department
6 The Ancient One/Aged Ghenis/Apocalypse-Knowledge & Understanding-thanos is prolly one of the most Knowledgeable people below abstracts
7 the Joker/Lobo/Dr Polaris-Insanity & Unpredictability-the mad titan,nuff said.as for unpredictability one minute he wants to destroy everything the next hes a Samaritan.
8 Adam Warlock/Merlyn/ etc- Anomaly( Different from the norm)-on par with them.
1 Xavier/Jean/Moondragon- Mind- Thanos is tough to beat on the psychic plane. He wins.
2 Gilamesh/Juggernaut/Merged Hulk- Strength & Durability- Tops them all in strength and durability. Only Classic Juggernaut could probably compete with him.
3 Reed/Banner/Doom/High Evolutionary- Intelligence & Tactics/Strategy - Thanos is superior to all of them.
4 Vulcan/SS/Maikail Rasputin- Energy Manipulating- Thanos relies mostly on his cosmic strength in battle. SS and Vulcan can beat him in energy manipulation.
5 Circe/SS/Molecule Man- Matter Manipulating- Same as above. SS and especially Molecule Man are better at it.
6 The Ancient One/Aged Ghenis/Apocalypse-Knowledge & Understanding- Thanos definitely. He's derived knowledge from both the Infinity Well and the Oracle that taught him about Tyrant.
7 the Joker/Lobo/Dr Polaris-Insanity & Unpredictability- The Joker at least has Thanos beat here. Nothing he does is predictable.
8 Adam Warlock/Merlyn/ etc- Anomaly( Different from the norm)- Warlock is the only character more of an anomaly in the universe than Thanos. That's probably why he's the only person Thanos really fears.
He MIGHT top Juggernaut in strength, MIGHT. But, he doesn't top him in durability. Juggernauts durability is skyfather level, he'd never get his heart ripped out by the likes of Drax. In a pure physical confrontation he'd eventually lose to the Juggernaut.
