Monkey is certainly one of my most famous characters - star of Damn It, Monkey!, this sufferer of indignity has been online since.. gosh. 2003. He's old. He can vote, even... if he were human.
Of course, I don't know how old he actually is, but with the comic in its third iteration over nearly two decades, I don't think Monkey is going anywhere. This super intelligent primate from space has a gift for inventions, and more accurately, making them explode. What character doesn't need a flaw? Fun fact: His only invention that never exploded was destroyed by his nemeses, the Martians, before it had a chance to, anyway. But it worked, several times, in fact - which maybe he should start reminding everybody of that.
