User blog comment:Cake is a lie/Your Favorite Sonic Character?/@comment-174.59.138.2-20130514014909

Dr. Ivo Robotnik, also known as Dr. Eggman.

The reason why he's my favorite is because no matter how much of a failure his evil plots to build his fabled Eggman Empire are, he always remains in high spirits, trying to think of new ways to destroy Sonic.

When he comes into contact with any of the other characters, (For example; Knuckles), he fools them into doing his will. (Such as saying it was Sonic who destroyed the Master Emerald in Sonic Adventure DX.) His charm and humor, strength of character and zeal, is the reason Dr. Ivo Robotnik is my favorite Sonic franchise character.
