If you have the instructions, or are just an expert on Zoid construction, you can help the Zoids Wiki by assembling this poor fella.
Mother Bio is a Tyrannosaurus type Zoid, one of over 200 species of biomechanical lifeforms depicted by TOMY's Zoids model, toy, and media franchise. The Mother Bio is unique to the Zoids Generations storyline and the related Generations model line.
The Mother Bio is the final antagonist Zoid in the Zoids: Generations Storyline. The Zoid is heavily based off of a Bio Tyranno, and featured two Bio Particle Cannons; one on the chest and the other at the tip of the tail although these were described as Heat Ray Cannons in the story. Only the custom seen in the Zoids: Generations story (shown left) is known to exist.
