Many years ago, before the roboticiser, Robotnik dealt in the process of creating "cyborgs" - half animal, half robot. However Robotnik quickly scrapped that project due to the fact that none of the Mobian Monkeys could handle it, except for one - Monkey Khan. Robotnik had built him to be TOO POWERFUL and as a result he ended up with a hotheaded powerhouse that he couldn't control. Locking Monkey Khan in a metallic crypt in which he couldn't escape, Khan rested there for 10 years until Sonic, Sally, and Antione accidentally discovered it and freed him. Sonic and Khan hit off on the wrong spot IMMEDIATELY and as a result they ended up fighting each other more than anything else. However in the long run they parted as friends as Khan left to return to his native home of the Dragon Kingdom. It wasn't until a few weeks later that Sonic and Tails discovered him at the base of Mount Stormtop under the control of The Iron King and Iron Queen. They managed to free Khan from the grip of the Iron Queen as well as destroying her "Eternal Flame" spell that she had set upon Mount Stormtop. Khan decided to stay there among the simple villagers and live out his supposed destiny as prophecised "Monkey King" of the Dragon Kingdom. He defended the villagers from various attacks until Robotnik (SA-style Eggman) took him off guard and captured all the villagers and roboticized them all. Monkey Khan has an intense hatred for all overlanders now. When Sonic was trying to warn the overlanders--who had just returned after a decade in space--of the dangers of Robotnik, Monkey Khan's attack in blind hatred scared the overlanders and they went straight into the "safety" of Robotnik.

Surprisingly Mr Blobnik was one of Doctor Robotnik’s better creations, or rather Grimers. Sonic and the gang responded to a call about a deadly badnik plaguing the Metropolis Zone when they discovered Mr. Blobnik and Sonic jokingly took the robot on alone. Robotnik watched Grimer controlling the robot from his Citadel, threatening him because of his “Ridiculous” creation. Unfortunately a Metallix arrived and kidnapped Grimer giving Robotnik the first sign that the Brotherhood was out of his control. Meanwhile Mr. Blobnik’s secret weapon was out of batteries giving Sonic an easy victory as he literally tore Mr. Blobnik apart. When Mr Blobnik exploded he released a gigantic bubble which captured Sonic and the head split apart from the rest of the body, sprouted arms so it looked like a spider, grabbed the harmless Sonic who was stuck in the bubble beneath it.

So Doctor Robotnik’s most ridiculous creation was actually the first to succeed in capturing Sonic but thanks to the Brootherhood of Metallix Robotnik let Sonic go free to face them.
