Mountain-Troll

The mountain troll (Troglodytarum alpinum)Illustration of Diagon Alley by Jim Kay from the Deluxe Illustrated Slipcase Edition of (see here). was a breed of troll. 
==Description==
They were the largest breed, weighing over a tonne, and also the most vicious. They were often bald beasts with thick, dark grey skin. They sometimes used Graphorns as mounts, though the Graphorns themselves eminently disliked this and many mountain trolls bore scars from trying to ride the creatures. Though possessing enough rudimentary intelligence to craft primitive tools and clothing, mountain trolls were exceptionally thick even by troll standards; on the night one got into Hogwarts, the general consensus was that it must have been deliberately let in rather than finding its own way in, implying they were too stupid as to even work out how to open doors.
==History==
In the 1989–1990 school year, Jae Kim and Torvus decided to trade with each other. Jae wanted a mountain troll's vest for a strange collector in Knockturn Alley, while Torvus wanted some herbs from the Hogwarts greenhouses.A mountain troll was used as a diversion so that Professor Quirinus Quirrell could attempt to get past Fluffy to capture the Philosopher's Stone for his master, Lord Voldemort. The troll discovered and attacked Hermione Granger in a first-floor girl's bathroom, wrecking the place and nearly killing the girl as well as Harry Potter before Ron Weasley used the Levitation Charm to strike it in the head with its own club, knocking it out. What happened to it afterwards is unknown.
