In Dai Sentai Goggle Five, the defeated Synthetic Beasts would get hit by the "Refresh Power" beam, and then sent into Humongous Mecha copies of themselves called Kongs to pilot, similar to Battle Fever J.The Monger will announce "Giant monger!" and grow on its own (typically right after the team finisher, natch).

In the early episodes, Battle Fever would have to defeat the monster while dodging attacks from the robot, then get in their own mecha to defeat it. Starting with Episode 5, the monster of the week would call a giant robot duplicate of itself. The first Mecha using Super Sentai, Battle Fever J, averted this.
