Voyager Grindor Bio
GRINDOR is a born soldier. He is both a highly talented fighter, and an instinctive strategist. Every moment of a battle is laid out in his head before the first shot is even fired. He is so talented at anticipating his enemy's moves that he is almost never surprised. Whenever he can, he ensures himself a place at the direct center of a fight so that he can bring his powerful weapons to bear on the AUTOBOTS around him, destroying as many as he can as quickly as possible.
