Gannen Harst is Vancha's brother. Remained a Vampaneze when his brother was re-blooded and became a Vampire. Gannen becomes Steve Leonard's personal protector, encourages Steve to try the coffin of fire to see if he is the destined lord of the vampaneze and possibly even the one who blooded Steve. Gannen is by Steve's side wherever he goes. Gannen in the end grows tired of his insane Lord but still fights for him, even wounding his brother Vancha. After Steve's death he, along with Vancha, impregnates Evanna.
Vancha is no longer sure which of them (he and Gannen) is the older brother, but judging by Gannen's looks and complexion, it is likely that Gannen is the younger brother.
Gannen is said to have long hair that reaches down his back. Like most Vampaneze, he has purple skin, red eyes, hair, lips, and nails. However, it might be noted that in the Manga version, his hair seems to be shown to be a lot darker than the other Vampaneze like Murlough.
He has been said to have a rough, never faulting face. A poker face, if you dare say. He never smiles (unlike his brother) and always seems to have a calm expression. He is noticably buffer than his two allies - Morgan James, and Steve Leopard but still slimmer than the buff Vancha March.
