Bakugan Battle Brawlers - Season 2 Episode 35

After Elfin overhears Preyas talking down about her receiving the energy and rash behavior, Elfin runs off into the city and encounters Shadow Prove and Hydron. Marucho and Preyas arrive in time to rescue her and a battle ensues. At first, Elfin and Preyas have trouble getting along but they put their differences aside and almost defeat the Vexos, but Elfin shields Preyas from an attack and therefore loses the Aquos energy. Preyas, out of anger for Elfin's sacrifice, easily defeats Hydron and Shadow Probe. After the battle Dan, Shun, Ace and Baron fall asleep during the movie that they were watching. No-one else knew Elfin lost the Aquos Energy. The Vexos only need 3 more attribute energies & they can make the Bakugan Termination System, functional.
