Count Vladsmir

Count Vladsmir is the leader of the Stradun, a faction of Monsters from the Monster World. He was spent his time unifying the monster factions to break the seal into the mortal world and plans to eclipse the sun, plunging the world into eternal night.

The First Nitro Rangers
The First Nitro Rangers were five Students from the first class of students at Reefside High School who met the fairy Gladdis as kids and were able to use their magic to become the Nitro Rangers whose quest was to seal Count Vladsmier and his hoard of Vampires in the monster world.

The names of this team have been lost to history, but the names of the former dorms in the area were the Nitro Powers were found could provide possible hints.

Gladdis' Grove wasn't fully cured of the Vampires damage and soon faded into unkempt wood where many years later, the Dino Thunder Rangers would rise.

Power Rangers Coaster Force
Charles Lashing sometimes walked into the woods in Reefside, and ended up finding a tiny wormhole. It was later found out to be a seal between worlds, so he employed his best student, Teddy Winslow, to create the Coaster Force Powers.

Count Vlasmier, in the 117 since had unified the monster factions and found the moonstones and was breaking the seal between worlds instead of eclipsing the sun in the mortal world. He sent a pack of werewolves out as they could disguise themselves as students. They real students were found by the Coaster Force in the first episode, which they then reported.

They were joined by Ajax, a ghost crane, in the second episode, which was destroyed by the Coaster Force Megazord after going gigantic by his faction's moonstone.

Power Rangers Nitro
The Skeletons were able to destroy all but Mel's powers, leading her to discover the Nitro Powers. The remaining five ranger who had no powers (as Teddy graduated) became the new Nitro Rangers and sealed them away, sending Vladmier into an approaching wildfire, which helped stop its expansion.

Personality
He is a cruel and crazy vampire. A dictator in the other factions eyes. He is only out for himself and put his hunting of the moonstones ahead of his love life, much to her dismay.
