Deep Blue is the leader of the aliens and the primary reason they have returned to the Earth.



Deep Blue is one of the few characters in the Mew Mew Power dub version whose name remains unchanged, however he is also changed from being a savior for the aliens to being a destructive force that wanted to destroy the Earth, which causes the others to turn against him. In the Mew Mew Power English adaptation of the anime series, he is voiced by Scottie Ray.
