To elaborate on the previous writeup, Exo squad was an Excellent American cartoon that aired from 1993 to 1995 in syndication. It could be found at odd times all over the country. In my area(Dayton OH) it aired on Sunday Morning.

The series was produced by Will Meugniot ( who is a big fan of anime. In this series he wanted to emulate a giant robot anime (see Mobile Suit Gundam or Macross), and IMHO he succeded wonderfully. The series was better than many anime of that genre (see Gundam Wing). Another interesting note is that the Voice casting was done by the Ocean Group, a company that dubbs a lot of anime.

Unfortunately, despite good writing, the series probably didn't satisfy the toy companies and it was canned. The good news is you can download episodes from a great fan site:
