Ivo Robotnik

"How I hate that hedgehog!"

Robotnik's line when he is defeated by Sonic

Ivo Robotnik, or Dr. Robotnik, is the overall main antagonist of the entire Sonic series. He serves as the villian in the comics, games, movies and shows.

Personality
Robotnik can be described as cruel, sadistic, and merciless, finding joy an pleas of mercy. He stated himself, "As much as I like watching someone grovel and beg". He also hates most activities that require movement and joy, such as music or games. He also disapproves of anything that is not manmade nor polluted, leading him to loathe wildlife and human activity. He becomes physically pained or enraged if any such activities are done, either scolding his nephew, Snively for it, or destroying his badniks with a hammer.

Appearance
Robotnik is an incredibly obese, large man with a stocky stature. He has 3 limbs that have been roboticized, including his legs and left arm. He is commonly seen with his war suit, which is a large body suit with a yellow cape, with black boots. The red suit has yellow stripes across it which wrap around the body and meet in the center, with a gray button in the middle. The boots have a prominent "V" shape at the cuff, and the toe is red. His non-roboticized limb has a grey armband on the forearm, and a black glove. His ears are metal lobes, which apparently have springs in them, allowing them to bounce away from the head. They also can unscrew. The shoulders of the suit are very large, reaching above his head. His mustache is the most iconic feature by far. It is orange in color, yet he has no hair on his scalp.
