User Recommendations for Mobile Suit Gundam 00

Main characters have similar backgrounds, and as result they are both pretty emotionless. Both series are mecha, and are about organizations fighting against terrorism. Also, Gundam 00's Innovators are somewhat similar to FMP's Whispered.

Very similar story line the main character with and evil past trying to make the world better around him

The plot is kinda the same, both group don't belong to the Army but they are fighting enemy for a better future......Mobile suit Gundam have more awesome fighting but Full metal panic are funnier.

Gundam 00 was explicitly inspired by Full Metal Panic, and it shows, copying its idea of having a male lead who was a child soldier in the Middle East, with a former enemy from said war coming to haunt him in the present, while he works for an extra-governmental organization that intervenes in conflicts with the goal of ending them, all while contrasting this millitary affairs with the lives of a high school couple. If you liked 00, check out Full Metal Panic for a better take on the same concept.
