Mutant of the Week: Onyxx

This week I have a much lesser known mutant again.  Actually, I had never heard of him until I hit random page on the X-Men info page.  I wasn't sure who to feature this week and decided to let destiny decide.  Hence; Onyxx.

Name: Sidney Green
First Appearance: X-Men Vol. 2 #171
Powers and Abilities: Superhuman strength and resistance to physical energy due to his craggy granite body.
Other Attributes: his granite body.  He also has a second set of eyes.

Onyxx was born Sidney Green and was orphaned at a young age and grew up in an orphanage and foster homes.  He was often bullied as a child.  When his mutation manifested he went to Xaviers school and was put on Gambits team.
He was critically injured by William Stryker.  Sadly there is not much more info on Onyxx since he was killed by Wither during an attack.
