Skate, as his name would imply, was a mutant skate. He was to appear in The Mighty Mutanimals (TV pitch), as Man Ray's cousin. Skate would be an anti-hero, operating for the purpose of justice but on the fringes of the law - something that would irritate Man Ray to no end.
Skate also appeared in the pitch for The Selected under the name Rajid.
As well as describing what sort of mutant he is, Skate's name also refers to the roller skates he wears.
His name for The Selected, Rajid, is not only a proper name, but also short for rajidae, the biological family name for skates.
