From: Bubblegum Crisis 7: Double Vision
Mako says: A one-of-a-kind Battlemover. Heavily customized for enacting the revenge of Reika Chang. This thing was a walking nightmare with enough tricks to lay waste to armies of Boomers. In this pic it's only standing at half it's total height!
From: Tenchi Muyo!
Mako says: Some explanation may be required here. True, she's not an actual crab. But her screensaver often features crabs running back and forth and her hairstyle is designed to mimic the look and color of a crab.
So with that out of the way- she's a diabolical mad scientist with a crazy sense of humor and an ego to match! And she's friends with Tenchi, oooooh!
From: Beast Wars
Psychotic, cannibalistic, masochistic, embodiment of pure evil. And he transforms into a crab!
From: Megaman Legends
Another badass crab mech, the first of two that Tron Bonne builds and pilots. Why is this one so cool? Well, up to that point in Megaman history, everyone was used to bosses that were about the same size as Megaman himself. This here is the FIRST boss of Legends! And it'll destroy the entire town if you let it!
From: Ghost in the Shell: Stand Alone Complex
Mako says: How can something that adorable carry semi-automatic guns and grenade launchers? Described as walking think-tanks, these things bring some serious firepower to the team at Section 9.
