10 Video Game Villains Who Lived Long Enough To Become The Hero

10. The Arbiter - Halo

A loyal soldier of the Covenant ‘Vadam was one their greatest sons, serving as the Supreme Commander of the Covenant fleet and inflicting billions of casualties on humanity during the Human-Covenant war, including presiding over the infamous fall of Reach.

Then it all went wrong.

Learning that the Covenant High Council had reneged on centuries old agreements with his species was bad enough, but learning that the Covenant religion was a lie and that the Halos were not holy relics but doomsday weapons intended to wipe out most of the life in the galaxy, and having the truth confirmed by a heretical human in the form of Master Chief, was the final straw.

‘Vadam switched sides. Forging an alliance with humanity, he would prevent the activation of the Halos, saving untold billions, and in time fight alongside Master Chief to defeat The Flood, saving untold billions more.

But his greatest achievement would be signing the peace treaty between his species and humanity, an act that would prompt Captain Thomas Lasky, a hero of humanity in his right, to say of him: "The Arbiter. Maybe more than any other figure, a symbol of what the galaxy could one day become."
