10 Movie Villains Killed By Their Own Weapons
3. Thanos - Avengers: Endgame (2019)
No MCU villain has ever worked harder to achieve their goals than the Mad Titan, Thanos. With staggering strength, both in mind and in body, and a fierce resolve to go with it, the purple pariah stops at nothing to get his hands on the Infinity Stones.
And, inevitably, he wins, wiping out fifty per cent of all living things and, in his view, restoring balance to the universe. So destructive is the impact he leaves that the Avengers even begin to consider time travel to reverse the effects of The Snap.
With careful planning, they go back to different points in time in order to collect the Infinity Stones before Thanos does. Their efforts catch the attention of the past version of Thanos, and he and his army launch a full-scale attack on the Avengers' Upstate base.
Despite being one man against a fleet of super beings, the Mad Titan is more than a match for his opponents even without the Infinity Stones. His end finally comes when Iron Man, realising what he has to do, sacrifices himself to snap Thanos and all his followers out of existence.
The poeticism of this death is in Thanos's quiet acceptance of his defeat. Rather than fight till the very end, he simply sits down and awaits his disintegration with dignity and stoicism.
