Silver Insanity

Name: Grar
Race: Displacer Beast
Gender: Male

Description:
Imagine a six legged black panther the size of a clydesdale. Give him spiky fur, mad red eyes, and oversized teeth and claws the color of dried blood. Two great tentacles arc upwards from above his shoulder blades, and the barbs at their tips are the same blood red as his claws. Add a thin, greasy, grey miasma boiling around him to a distance of a few feet.
He moves with all the grace and precision of a tank, and achieves much the same impression of implacable destruction.
The only notable piece of gear he has is a pair of thick (and somewhat rusty) iron bracers on his front set of legs. There could easily be more equipment hidden under his fur, however.

Reputation:
Strength: 50
Dexterity: 20
Constitution: 40
Intelligence: 6
Wisdom: 10
Charisma: 10

Grar is a henchvillain for hire. He's usually seen at the side of a necromancer or other powerful evil individual. His raw strength in combat is often far greater than those he serves, however.
In combat, he goes berserk - attacking whatever is in front of him in a blind fury. He is also known to have phenomenal resilience and regenerative capabilities.

There are a few tales circulating in which he was defeated (or even turned against his former master) by trickery. However, the best tactic seems to be waiting to engage his master until he's been sent elsewhere. Without someone to formulate plans for him, he represents only a minimal threat; capable of destroying a village or two, but not able to perpetrate any truly large scale atrocities.

Many, particularly low level, people regard Grar as some form of demon - a reputation which he seems to relish and encourage.

And, for reference, here's the original D&D character sheet, along with a few notes.

fudges:
Removed trap sense and uncanny dodge abilities from barbarian levels.
Increased in class skill list for barbarian levels.
Feat progression fudged slightly so Grar wouldn't have to wait two extra levels to get the second requires-rage-as-a-pre-req feat to get into frenzied berserker. This is just a matter of timing; he does have the minimum four levels of barbarian that would allow two feats if the first level had landed on a multiple of three.
Went up to EL22 to get the key fourth level frenzied berserker ability. Starting equipment reduced to EL 18 gold value in compensation.
Used strength bonus for intimidate checks.
