Titans are much larger than humans, and their physical constitution is strong enough to wield the Infinity Stones without strain and easily overpower and severely injure beings as strong as Vision, Hulk, and Thor, as displayed by Thanos. Titans, despite their large size, possess incredible superhuman speed and reflexes that allows them to easily outmaneuver and overwhelm not only other beings of similar sizes, such as Hulk but also even smaller and highly agile individuals as well, such as Loki, Drax the Destroyer, Gamora, and Iron Man in his Mark L Armor. They are also able to react swiftly to high-speed projectiles. Once an advanced race, Titans suffered from overpopulation, as their home planet eventually ran out of resources. Thanos offered a solution, to randomly kill off half of the population to save Titans from extinction, however, his people disregarded Thanos' genocidal proposal, calling him a madman. Subsequently, Titans turned on each other for survival, which resulted in major conflicts across the planet and the near extinction of all Titans, with Thanos and his adoptive brother Eros being the only survivors.
