Since Wolfsfang isn’t around to post this himself, here’s his character, HE.
He is possessed by the ancient souls of 1000 long dead evil warriors and sorcerers that predate King Grayskull and the Elders by thousands of years.
The souls of these evil people were trapped /imprisoned inside a purple orb called the "Dark Heart Stone" but the spell that trapped them was faulty. Instead of keeping the souls in a spiritual form of suspended animation it trapped them in a dark void with total sensory deprivation. They couldn't speak, they heard nothing, saw nothing and so on yet they were aware of every passing second.
Then there was the problem that time works differently within the void, 1 second of normal time was about 10 billion years in the void. Which considering the actual thousands of years they have spent locked inside it they have been basically awake for 2524554080000000000000 years in total blackness.
This orb gives him access to a number of powers and abilities.
1*Super Speed - up to 500 mph
3*Highly resistant to injury (but not totally invulnerable)
4*Ancient Magic as strong as that of the elders (if not slightly stronger)
5*Super Strength. If He-Man's strength level was 100...He's would be 180
6*Knowledge of many armed and unarmed fighting styles
