Thanos operates on an altogether different scale of devastation. His infamous snap eliminated 50% of all life across the universe, a figure that defies meaningful comprehension. If applied to Earth alone, this would represent approximately 3.9 billion casualties, exceeding every war, plague, and natural disaster in human history combined. His conventional military campaigns across Titan, Gamora's homeworld, and Xandar demonstrated destruction capabilities rivalling major extinction events. The Children of Thanos alone conquered dozens of planets before breakfast.

Thanos's resource acquisition methodology proved devastatingly effective. He successfully collected all six Infinity Stones, artefacts of such rarity that their combined assembly had never previously occurred. His armies stripped countless worlds of technology, personnel, and valuables. Most significantly, Thanos understood resource reallocation: by eliminating half of all consumers, he theoretically doubled per capita resource availability. His acquisition strategy, whilst morally abhorrent, demonstrated understanding of zero-sum economics at universal scale.

Thanos's motivational influence extends primarily to fear and reluctant compliance. His subordinates follow through terror rather than inspiration; even his adopted children plot against him. However, Thanos successfully motivated the entire Avengers initiative to unite despite considerable interpersonal conflict, and his threat prompted technological advancement across multiple planetary civilisations. His single-minded pursuit of the Infinity Stones demonstrates motivation bordering on pathological obsession, achieving goals that required millennia of patient accumulation.

Thanos's effects proved surprisingly reversible given their magnitude. The Avengers' 'time heist' and subsequent Hulk snap restored all eliminated life, demonstrating that even universal genocide can be undone with sufficient determination and access to temporal mechanics. However, Thanos's destruction of the Infinity Stones was intended to be permanent, and his erasure of Asgard and other civilisations left scars requiring generations to heal. His reversibility exists only because heroes intervened; without opposition, his effects would persist eternally.

Thanos, being a Titan Eternal, possesses a lifespan of several millennia, having pursued his obsession for approximately 1,000 years before acquiring the Infinity Stones. His influence persists across Marvel's multiverse, with variant Thanos iterations appearing in countless timelines. However, the original Thanos was definitively terminated by Thor's Stormbreaker, and his legacy proved reversible through time travel. His persistence, whilst impressive for a biological entity, remains finite and ultimately defeatable.
