I don't exactly know the name of this anime/cartoon so here I am describing it.
It was aired in 2002 on TV. The story contained mainly an alien invasion and a force of power armor guys who fight the alien. The main guy rode on a surf board type of thing while he was launched from a truck which has catapults to launch people. The fight ended then with the force divided in 2 groups who fight for ultimate power. There was something called Giam which was in 2 pieces and the one who combined it get a lot of much power in his suit.
The suit the main guy is using is blue and white, and the gun he use while fighting is some sort of laser beam type. I also remember one word from end credits and it was like 'm-divers' or 'm-drivers' or something like that.
I assume the series has more than 2 or 3 seasons and also the total span is nearly 70 to 80 episodes. I watched in Hindi(India), but I think it was a US or Japanese origin story.
If anyone knows about the show please give the name; I have been searching for it for the last 6 months.
