Vinny Doombats
Faction: Transylvito
Class: Warlord
Special: Leadership, Royal

Proposed Canon

A Warlord and Count^Erf-b1-p034 in the Transylvito faction.

Speculation

Vinny looks like a vampire (as apparently all characters in Transylvito) and sleeps in a coffin^Erf-b1-p044. However, he does not seem to be affected by sunlight.^Erf-b1-p042

Vinny seems to be a friend and confidant to Prince Ansom.

He was deployed along with his Doombats as Tryansylvito's part of the alliance.

Real World References

His name is a reference to Vinny Goombatz, a fictional character created by stand-up comedian Rodney Dangerfield.
