Play Kettou Beast Wars - Beast Senshi Saikyou Ketteisen (Japan) Online

Kettou Beast Wars - Beast Senshi Saikyou Ketteisen came out in 1999 for the Game Boy Color, developed by Takara. It was part of that wave of licensed games that tried to capture the look and feel of the show, even on the small screen.

You pick either Optimus Primal or Megatron and fight through a series of one-on-one battles against other characters from the Beast Wars series. The combat is straightforward; you punch, kick, and use special moves, with the ability to transform between beast and robot modes during fights. Matches are fast and can feel a bit stiff by today's standards, but pulling off a transformation at the right moment still gives a little thrill. It feels like a quick, no-fuss brawler made for fans who just wanted to smash their favorite characters together.
