Beetleborgs Metallix ends without resolution because the monsters finally ate the kids.Once the Beetleborgs no longer existed, the door to the 2-D universe was sealed, meaning the Crustaceans could no longer sustain their existence.
Alternatively, the series' resolution happened offscreen......And it was with Zordon's energy wave destroying the Crustaceans and taking away the Beetleborgs' powers once and for all.
Those early ads where all this originated from space......Are of the in-universe comic, which would of course have a different story from the show.
Beetleborgs will receive a reboot adapting Kamen Rider Kabuto
- Why not? Saban has filed a trademark, plus the costumes are pretty much unknown in the US.
