Richter was once challenged to a battle by M. Bison, Rugal Bernstein, and Dio Brando. They were going to be paid hefty sums of money if they could defeat Richter. But what they didn't realize is that no one challenges Richter to a battle and lives: just look at what happened to Wolf.
Dio tried using The World to stop time. Richter made time continue, reversing The World. He used the Vampire Killer (Dio IS a vampire after all...) to whip Dio in the face.
M. Bison tried using Mega Psycho Crusher to kill Richter. Richter knows he can't be killed so easily, so he countered with Thousand Edge. M. Bison was destroyed.
After seeing Dio and M. Bison fall, Rugal tried, in desperation, to steal Richter's Awesome. You cannot steal Richter's Awesome; You are only blessed with it. Richter decided to implant 5% of his Awesome into Rugal for fun. It was too much, and Rugal lost his left eye because of it.
Richter found out who was paying these thugs. It was none other than Dracula. The fact that Dracula wasted Richter's time made him angry.
It was Dracula's final mistake to make Richter angry. In anger, Richter punched the first skeleton. It automatically killed Dracula by association.
