Hey

The Heys are a humanoid alien species whose language is only composed of the word "hey." They are described as dangerous deranged nihilists, chatty and ceremonious by the Whats.

History
The Heys develop two weapons, the Big Nothing, which inserts a black hole into another black hole to destroy the universe and the Infinity Ball, which tracks down their enemies and attempts to destroy. Then the whole population stations their ship in front of the black hole at the center of the universe and listens to their leader’s "farewell to everything" speech for thirteen years. Finally, the leader throws the Big Nothing into the black hole, except to be interrupted by the superhero humans Tick and Arthur. The Tick barely pulls the weapon out of the black hole and the Infinity Ball floats in to destroy the Tick. The Tick easily defeats the weapon and the entire Hey population worships the two heroes and returns them back to earth.
