An anime I watch years ago, forgot a lot of details but this is what I remember. Different countries each send a pair to represent them and battle it out. I'm pretty sure they fought using mechs. Even though they were in pairs there was only one mech on each side, I think it took two people to pilot the mechs. I think at least one of the mechs was named after a god, think it was the one from Greece, but i can't remember if any others were. I don't know what they were fighting over, maybe resources or power.
...G Gundam? Though mechs were single pilot. Sounds kinda like Dual Parallel as well, yet not. hrrrrmmm.....
No, it wasn't a Gundam series or Dual Parallel. If it helps I think both of the Japanese reps were guys.
Heroic age? although it isn't double pilot, the main mech is based on mythical heroes like hercules other possibilities is: Aquarion fafner Eureka 7 if you mean people piloting big robots
Yes it's Gigantic Formula. Now I just need to find a site that has it, because none I know seem to. Much thanks to all of you.
