The monsters of the week from the Super Robot Anime, Brave Raideen. The first half of the monsters, called Fossil Beast, were created when a bunch of rocks pile together and are merged into one Fossil Beast when it's granted life by Gante. The Second half of the monsters are called Colossal Monsters. The second half of the monsters are usually two giant monsters who battle each other, and the winner gets to fight Raideen.
