Everybody knows Groot. After his star turn in the Guardians of the Galaxy comic books and two (count 'em two) big time Hollywood movies, Groot is a household name, likely the most famous of the Kirby monsters.
But it was not always thus. Originally the cute Groot was merely another alien invader, a monster who fell victim to the enemy of most wooden thing -- termites. Since then, he's been revised as an ongoing character. As cute as little Groot is, I find a soft spot in my heart for the deadly original.
More monsters are coming tomorrow.
