What is the title of cartoon series (back in 2001 or 2002, i think) with a mail called mr. alien?

I am not sure if it is in fox kids or cartoon network. But the gyst of the show is that there are a group of girls who flies some spaceship. And they found a ship which was driven by a mail. They call him Mr Alien. The mail ship connects to the female ships and when it does, the resulting ship has a new function/ability. I was only able to watch a single episode so I really don't know the plot. Hope somebody could help me get the title of that cartoon series. I remember one of the girls being in loved with the guy and he asks him that he should only connect with her ship. The guy being the quiet type, just does his work to save those that are in trouble. I think he is some type of prisoner among those girls. I was able to watch it in cable tv sometime 2001 or 2002. I reside in asia, so that means it is possibly fox kids asia or cartoon network asia.
