Don't worry about the unavailable video, I changed it for a different one some time ago. Fun fact time for each series.
1. Victory Gundam has the youngest protagonist at 13. He also has the highest kill count and the series is the darkest Gundam series. A lot of named people die.
2. G Gundam is kind of like early Dragon Ball, but with mechs. The Gundams even go Super Saiyan. The protag is pretty much a shonen jump character, and he is voiced by Tomokazu Seki which is the voice of Gilgamesh.
3. Gundam Wing was the first Gundam show in America. The show had a lot of flaws but its still good. The sequel movie is peak.
4. Gundam X is underrated in the franchise, but its my favorite from this selection.
5. Turn A Gundam most people say is the best Gundam show in the entire franchise. The main Gundam and other mechs were designed by legendary American artist Syd Mead. Soundtrack by Yoko Kanno.
