Does anybody recognize this old cartoon?!

as a kid and I mean well before 2000, i remember there being this show where humans where fighting a race of aliens that were just giant hmans and the humans fought them in robotic suits that had 3 modes plane, walker like thing, and giant robot!. the humans also had found a giant spaceship/gun that in one of the episodes activated and drove off the invaders i still remember when they first tried to fly the ship the engines just popped out and began to fly off at one point the giants shrunk themselves to spy on the humans they did not understand the emotion of love and were disgusted by it sometimes they would use it as a wepaon they continued to war in sspace for most of the show they converteed the ancient ship/wepon into a city, in the first episode the hero had acuired a suit in plane form and accidently transformed it into the walker form not sure if that helps but if any one knows what the name of this show was please let me knowWww@Enter-QA@Com
