Crocbot

Originally hailing from the rough terrain of Downunda, Crocbot is probably one of the strongest Underbosses Robotnik has. However he is also the largest evil streak - and would do anything in his will to not only dethrone Doctor Robotnik, but kill Tails at any cost, especially seeing as how it was Tails who was responsible for destroying his body and fusing him permanently to his tank with a bomb. Upon reaching Downunda, Tails encountered the Downunda Freedom Fighters - a group of Australian FF's that sought to free their country from Robotnik's rule. Inviting himself on his quest after he was rescued and taken to Athair - Knuckles' grandfather, Tails and Guru Emu - in an attempt to rescue one of their comrades, Wombat Stu, let loose with a supply of Bomberangs. As Crocbot was hit with the bomberang, his tank skidded out of control and went flying into the Floating Island crater where the tanks nuclear core exploded. But Crocbot was NOT gone for good. After Tails left he set up his new base in that very crater. Taking his new army of Combots on loan from Doctor Robotnik, that area served as his base of operations until The Downunda Freedom Fighters destroyed it and finally liberated their country from his grip. This time Crocbot lost the entire lower half of his body, but he still wasn't through - he had managed to capture one of the Downunda FF's and implanted a mind control chip on him. It wasn't until Sonic and Tails came along on their quest to locate Ixis Naugus that Crocbot was finally stepped on for good. Taken in custody, Sonic took Crocbot's battered remains back to Mobotropolis only to have it stolen by part of Snively's gang in an attempt to revive all of Doctor Robotnik's associates after his "death" - the possible purpose being to fully rebuild him. Crocbot's whereabouts at this time are unknown.

Crocbot is a green crocodile badnik with yellow eyes and is fused to his mega mech tank, thanks to Tails.
