Killface

Killface is a fictional supervillian on the Adult Swim show Frisky Dingo. He is a large, pale white alien. His plan is originally to push the earth into the sun, but when that fails, and he inadvertently cures global warming, he decides to take the credit for it and use it to springboard his campaign for the presidency, which also ultimately fails because he is not a citizen of the United States.

Killface: Here's your twenty billion, Brent! Soak it in!

"Well, son, nobody wants a new mommy for you more than me, but the fact is -- (Simon begins to push his bowl off the table) THAT THAT'S OUR LAST BOWL! *sigh*"
