Bakugan Battle Brawlers Season 11 Episode 4 Infiltrated

The Brawlers hitch a ride to Gundalia on Dragonoid Colossus. Once they arrive, Ren announces that in addition to Jake, he would also like to rescue his former teammates who are being held captive in Kazarina's lab. Suspicious, Fabia joins Ren as the group splits up. In the meantime, Dan, Marucho and Shun go after Jake; but soon, things take a serious turn for the worse when Barodius ambushes the Brawlers and separates Dan from the others in an attempt to seize Dragonoid Colossus.
