El Cid

01Tilikum was responsible for three human deaths: Keltie Byrne (1991), Daniel Dukes (1999), and Dawn Brancheau (2010).
02Despite the deaths, SeaWorld continued using Tilikum for breeding; he sired 21 calves, propagating his genes through the captive population.
03He was captured at age two, separated from his mother, and held in a concrete pool — trainers noted severe psychological deterioration over decades.

El Cid's corpse was strapped upright on his horse Babieca and sent into battle after his death — and the Almoravid army reportedly broke and fled from a dead man.
