Gundam (ガンダム, Gandamu) is a meta series of Japanese anime, featuring giant robots, or "mecha", created by Sunrise studios and Bandai. Mobile suiit Gundam story is about war between earth and colonies from outer space due to some certain reason or dissatisfaction of both side.
Gundam created as a mobile weapon in the battle field..well, as a die hard fans of gundam, i could not agree more that gundam is a very nice anime, this is because it show how advance of technology used in war in the future, how a human can control a mobile suit during the battle, how big the damage it can create.
There is a lot of different series of Gundam anime, every gundam has their own abilities at the battle field such as light saber, beam canon, giant machine gun, and missle.
After i watch the anime, i think gundam do exists one day in the future due to the improvement of the technology, besides there is something we can learn from Gundam that is stop war.
