#Arrow | Who is Mark Desmond?

Mark Desmond, AKA Blockbuster, was a chemist who had wanted to become stronger, having been scrawny as a youngster. Experimenting on himself, he created a serum that made him grow stronger and taller, but in the process was turned into a mindless brute; an additional side-effect of the serum was that it took away his power of speech. Desmond was cared for by his criminally-minded brother, Roland, who shielded Mark’s monstrous appearance from their mother.

Blockbuster served as a member of the Secret Society of Super Villains and the Suicide Squad

Could he be an inmate at the Slab?

Could Oliver get out of jail for missions with the Suicide Squad?
