It was a show I used to watch in the 1990s. It had all sort of robots good and bad. There was one good human. The good guys got vehicules that could form up into a big one. One of the good robot was almost all black, ninja like, with 2 arms on one side and a crossbow or something on the other, he wore a mask. Another good one was a construction like robot, his name sounded like jammers...
