I am searching for the name of a cartoon which was broadcast on Cartoon Network (India) between 1998 and 2002. This cartoon aired around 4:30. The cartoon seemed to be Japan-made.
The cartoon depicted battles which happen in space. The main characters were two boys and a girl. There was a spaceship which these people live on, and there was a princess which they had to save from villains.
A super hero appeared whenever conflict arose, and one of the main characters took control of this hero. He got support from others, too - when he joins with his friends they can change as dragon and tiger.
