Sharps: the Frost Mage.

Sharps is an alien from Darkspore. He was only seen in a sketched concept at Comic-con 2010. The Drawing calls him "Sharps" and enlists him as a "Frost Mage". Sharps does not make an appearance in the game, as Frost was a removed genesis idea, and it currently is under Plasma, although no heroes or NPCs can use ice-based abilities. Frost may be included in a later expansion, but it has not been confirmed. Sharps was probably a tempest due to him being a "Mage".
