Little tricky as I didn't know the characters, but basically the big evil robot was kicking the stuffing out of two goody robots in a big chamber. One of them, the more beaten up one, sacrifices himself to block an attack intended for the other and transfer his Zentrium (?) to the other to make him double-power. The fight steps up a gear as the enhanced goody goes to war while the young girl (princess?) arrives with other humans and little robots.Despite the power boost it rapidly becomes obvious that the evil guy is just toying with the remaining goody. However, being the hero type, he has a cunning plan. He sets himself into a sort of overload mode and lures the baddy into a different chamber through a hole blasted in the chamber they'd been fighting in to that point. He asks the little girl, on a secure frequency, to power up the time machine in the second chamber.He then proceeds to get a body-lock on his opponent as he approaches meltdown, dead centre in the time machine. The girl doesn't want to trigger it, but finally does and both combatants disappear, ending the threat - but not before the good guy ejects his Zentrium.Things then get wrapped up - the little girl says goodbye to a boy and is visited by the goody robot in a dream-like way, before returning to her own time with a professor type chap using the time machine.Apologies for the lack of names but I wasn't paying that much attention really and it was a lot to take in!
