Ferris Boyle

Ferris Boyle is a villain in Batman: the Animated Series. He is the main villain of the highly-acclaimed episode "Heart of Ice".

He's a ruthless Gothcorp CEO who falsely promotes himself and his company in a positive light publicly, and was nominated for Gotham's "Humanitarian Industrialist of the Year" award. However, in reality Boyle was a vicious, greedy and heartless man. A year before the episode took place, he broke into the lab of Dr. Victor Fries with guards and kicked Victor Fries into a batch of chemicals, leaving him to die, just for using his company's equipment without authorization. Fries survived, but was severely mutated by the substances and transformed into Mr. Freeze. Now, on a vendetta against Boyle, Freeze traps Batman and leaves him in his hideout, confronting Boyle at the Gothcorp Humanitarian Party and freezing him up to the waist. Boyle begs for his life. Mr. Freeze gets ready to kill him until Batman confronts Freeze at the party, fighting him one-on-one until he breaks Freeze's helmet with a flask of chicken soup. Freeze is defeated, and arrested along with Boyle, as Batman presented evidence of Boyle's crimes to the press leaves him half encased in ice, saying "Good night, Mr. Humanitarian."

He went to prison after he was exposed.

In the comics, Boyle wanted revenge on Mr. Freeze for losing everything, but he got killed.

Ferris Boyle was voiced by Mark Hamill. The producers liked his performance so much that they replaced Tim Curry, who was supposed to play The Joker, with him, partially because Tim Curry's portrayal was too scary for kids. The Joker became Hamill's most iconic role, next to Luke Skywalker.
