Lionel Van Helsing is Dracula's best friend and the main antagonist in The Grim Adventures of Billy & Mandy episode "Dracula Must Die".
He was voiced by Dorian Harewood.
He wanted to kill Dracula because Dracula married the girl of his dreams, Tanya, who he instantly fell in love with when he bumped into her on the street. When he found Dracula had made his move on her. In the 70s, he had an afro and colorful clothes. In the 70s, he and Dracula were best friends.
As seen in a flashback, they worked a teddy bear factory and went out dancing and eating pepperoni pizza.
Grim, Billy, and Mandy validate this by finding matching friendship bracelets on Van Helsing and Dracula. Van Helsing tells them he promised to keep wearing his until he killed Dracula. However, Tanya bursts into the warehouse they were in. It's revealed that Tanya's son, Dick, is half vampire and half human while his sons, Irwin and Melvin, are half mummy, one quarter vampire and only one quarter human.
After seeing how Tanya now looks and treats him as well as how miserable Dracula is with his nerdish offspring. Lionel realizes that he's actually better off than Dracula, and struts out of the warehouse as Dracula begs him to destroy him but is ignored.
