Albert Dumblydore is a principal of Portal High School (during his term known as the Skool), being such since AG 1823, according to Enchiridion Marrissa. He was demoted in AG 1976 by Sectumsempra Sanpe.
The principal of "Hogwortc" is briefly mentioned in Jenny Weasley and Harry Potter's story. As it appears, Mr. Sanpe killed Dumblydore and escaped to Portal High School. It is confirmed that this principal/headmaster is really "Dumbldeore" in HARRY POTTER AN THE KILL OF SNAPE. In that respect, his successor is Gobo Fraggle.
He first appears in Marrissaverse Stories 2015, stating his famous line from My Immortal, "WHAT THE HELL ARE YOU DOING YOU MOTHERFUKERS!" He also notices that someone dropped a letter at the doorstep of The Skool "from Indian Poles to McJuggerNugget", which he has no idea what to do with.
