I'm going come out of left field on this one. People have already recommended Gundam. But I am recommending G Gundam.
The premise is all countries have moved their rich population into spacy colonies. In order to decide the space election, they send giant mechs down to the earth to fight a proxy war with no regard to the collateral damage incurred by the poor on earth.
Every character is a ridiculous stereotype of their country ala street fighter with mechs.
It is packed to the brim with cool guys doing cool guy stuff. One character is basically Apollo Creed and an other is basically Drago. And there is a character named goddamn Master Asia.
If you line up the plot of G Gundam with the plot of the Metal Gear series the main plot points almost match identically. Tone wise and crazy wise they are also pretty similar.
