Father Time

Description
Father Time appeared in the episode It's Time. He is made up of many different types of clocks, and was angry that Mordecai was the one microwaving all of his "limbs." He wears a purple hat, has a deep voice, and is able to materialize wherever he pleases. All his stuff is invisible, and he got mad at Mordecai for "wrecking his living room," which was also invisible. He forces Mordecai to reflect on his jealousy to Rigby. At first, he said that Mordecai must stay at the end of time forever. But then, he concedes that "houseguests really annoy me," and he let Mordecai start over again. He tells Mordecai to ride the "time pony," back, and get out of father times dimension. He was not seen since then.

Trivia

 * One of his digital clocks reads 4:20, as a reference to stoner culture.
