Dark Moon is the 25th episode of Bakugan: Mechtanium Surge. It aired on August 7th, 2011.
With Razenoid's Catharsis complete, Mag Mel decides to put all the humans into the dark reverse dimension of Earth to torture them. Meanwhile, the Dark Moon sends out energy waves which transfer all the non battlers to the reverse dimension. He also summons 5 different attributed Razen Titans to the 5 biggests cities on Earth to drill holes into the Earth's core which will result in the Earth blowing up. He then appears in the sky as a vision to all that he will do the same to all opposing forces including Gundalia, Neathia, Vestal and New Vestroia. The Brawlers decide to split up and hunt down the Mechtogan Titans but this proves not to be simple as there are armies of Chaos Bakugan and Dreadeon Clones as protectors. The grand battle begins with the Brawlers summoning their Mechtogan, Dan with Rapilator and the addition of Drago, Zenthon and Zenthon Titan defeating the first one, and Shun who summons Faser Titan and defeats another one. As the battle continues, Rafe with Wolfurio and Paige with Boulderon are having difficulty but then, the Vestal Destroyer arrives with Spectra Phantom, Infinity Helios and Gus Grav on the bridge. He then comes to assist them and they defeat another Razen Titan. After this, he with Dan and Shun then come together to face three more Razen Titans.
Spectra then suggests another mutation between Helios, Drago and Taylean. They accept this and form Mercury Dragonoid, Mutant Helios and Mutant Taylean. These mutants then defeat many Chaos Bakugan and they split apart. Then, Drago and Taylean merge again and deals some more damage to the Razen Titans. Mag Mel retaliates by not only summoning more Razen Titans but also arrives with the evolved Razenoid too. He then binds Dan and Drago in a knot and the Brawlers Mechtogan fight back. However, Razenoid proves to be too strong and manages to survive and defeat all of their Mechtogan. Specta tells to Gus that send the data for the Bakugan Battle Suits over; Doomtronic for Helios and Blasterate for Taylean. The two manage to break Razenoid's shield and knock him back but he manages to survive and attacks everyone, including the Brawlers themselves. Mag Mel begins to taunt Dan by attacking the other Brawlers and Marucho forms a small plan. Taylean and Helios then attack Razenoid while Tristar reminds Dan and Drago about the gate and key which since they have, can possibly close the Dark Moon. Razenoid then blasts Tristar who gets up later as Dan and Drago fly up to the moon after breaking free with Mag Mel and Razenoid coming from behind. The destiny of the Earth it's on the hands of Dan and Drago just as Spectra said.
