Thanos
The Mad Titan's power portfolio reads like a cosmic arms catalogue. His Eternal-Deviant hybrid physiology grants him strength sufficient to overpower the Hulk, durability that shrugs off conventional weaponry, and centuries of tactical refinement. Standing over two metres of purple determination, he commands respect through sheer physical presence.
With the Infinity Gauntlet, his capabilities transcend mortal comprehension. Control over reality, time, space, soul, mind, and power simultaneously renders him functionally omnipotent. A finger snap could erase Yoda from existence before the Jedi Master completed a single grammatically inverted sentence. This represents power at its theoretical ceiling.
Without the Gauntlet, Thanos remains formidable but beatable, as various Avengers demonstrated with sufficient coordination. His power depends significantly on accessorising with magical jewellery, a dependency that proved fatal.
Yoda
Master Yoda's power manifests through nine centuries of accumulated Force mastery. His connection to this mystical energy field enables telekinesis sufficient to lift starfighters, precognition that defies temporal logic, and combat abilities that transform his diminutive frame into what observers describe as an aggressive green pinball.
The Jedi Master achieved stalemate against Emperor Palpatine, the galaxy's most powerful Sith Lord, demonstrating force projection and lightning deflection at the highest documented levels. His Form IV lightsaber technique compensates for his 66-centimetre height through velocity and acrobatic unpredictability.
However, Force abilities possess inherent limitations. They require concentration, can be disrupted by sufficient opposition, and notably failed to detect the clone army conspiracy occurring directly under the Jedi Temple. Raw power proves irrelevant without wisdom in its application.
