Crystal Jewels/Season 1/Episode 18

Don't Mess with Brawlers!
In the beginning of the episode, the brawlers have deserve a rest after Roaracryst's big fight against Thundering. So Kouchu and his friends have decided to rest after Roaracryst is beginning to feel very tired. When the brawlers went to sleep, something unexpectedly happened during the night. The Marukas are in the laboratory planning to get the Crystal Balls in order to make Marcy Kimensho proud. Then, as Marcy went to sleep, the Marukas sneaks out of the house, and into their private lab to make their own invention "The Mind Control Collar" so they could get the Crystal Balls.

The Marukas uses the radar to search for the Crystal Brawlers. When they appear in front of their shelter, the Marukas went in to see who to mind control. Shauna is the first choice to mind control, but her ponytail is in her way, where the Marukas stated that if the Mind Control Collar detects any hair, it will malfunction. Then, they have tried to look at Sakuro, but it would malfunction too on him. Their final choice is Kouchu, so the Marukas have woke him up from his sleep and uses him to get the Crystal Balls for them.

The Marukas have told Kouchu to grab the Crystal Balls away from the brawlers, and all of the Crystal Balls are picked up. So Kouchu, while being mind-controlled, are being brought by the Marukas to their lair to see the Crystal Balls. When there happens to be the breeze coming in the brawler's shelter, at first, Shauna have complained about it, but she also have noticed that Kouchu is missing from the shelter. She, Roaracryst, and the others set out to look for him, but Roaracryst saw the foot tracks, and he suspected that the Marukas are up to no good.

The Marukas have finally brought Kouchu to their lair so they would center all of the 9 Crystal Balls so they could get more power. Just before they can begin the ritual, Roaracryst, Shauna, and Sakuro jumps in, and notices that Kouchu is being hypnotized. As Roaracryst tries to get Kouchu to snap out of it, he notices a collar. Roaracryst manages to break Kouchu's collar off, and Kouchu returned to normal. As the Marukas are angry about this and begun to attack the brawlers, Roaracryst also charges at them and he trap them in his webs so they won't escape in a minute. The brawlers escape to get some rest. Later, the Marukas are loose from Roaracryst's webs.
