Just Spitballing here, but I was thinking something like :
HC: A Modern Prometheus
Trouble: I Don't Know My Own Strength, or Fear of Fire
Other Aspects: Strong an an ox, Doesn't understand Humans, Misunderstood Monster, Built like a Tank.
Maybe something like Quick Learner (he picked up languages and was reading Paradise Lost in a short time), Driven by revenge, All Alone in the World.
As far as skills:
Might and Endurance ought to be high. Fists, Survival, Intimidation, Athletics also should be up there. Maybe Scholarship or Lore for his quick learning. Alertness should be up there as well.
Stunts:
Some sort of Grappling stunt. He strangles his victims.
No Pain No Gain
Lethal Weapons
Street Fighter
Powers:
Living Dead
Strength, Toughness, Recovery powers of some sort
Hulking Size
Again just my first ideas.
