Guardna, the Shapeshifter

Description:
Is an alien life form from the planet Parzak. One of the last males of his kind, and has become very bitter. As such, he enjoys stalking the weak, breaking those with cheery, bubbly personalities, and psychologically torturing his victims. He has demonic, pointy ears, along with a sharp row of teeth. His human-like torso is very fit, and uses it well to disguise himself among humans. Though he can turn into anything he wishes, his true form, below the waist, is a twister of flesh.

Backstory:
As a young alien, Guardna was once bright and optimistic. It all changed when pink, cartoonish, monster girls began inhabiting his planet. Though not actually attacking his kind, they drove him insane with their laughter, constant singing, and general stupidity. They tried to force them off Parzak, but it was simply no use. Guardna was one of the very few who secured a spaceship and left his home world. He abandoned his once good outlook on life, and became a cold, bitter shell of his former self.

He swore to destroy all cute and cuddly, those who wear pink, and those who are happier than him.

Personality:
The past Guardna was kind, benevolent, optimistic, and bubbly. After the invasion of his home world, he became a monster. He was now megalomaniacal, sadistic, bitter, full-of-hate, and downright cold.
