The Legendary Soldiers of Vestroia (also called the Ancient Warriors) are Bakugan who defeated an army of Gargonoids long ago. Since then, they have become legends, and preside over Vestroia from the Doom Dimension. There is one of each Attribute.
When the Battle Brawlers came to the Doom Dimension they were met by the Soldiers and a deal was struck, if all of the Brawlers could defeat the soldier that uses the same attribute as them they would take them out of the Doom Dimension and let them take all of the Bakugan that Masquerade and his minions sent there. They all won, so the Soldiers had to keep their end of the bargain, using their Attribute Energies. In New Vestroia, the Soldiers reappear conversing with Drago and giving him a body, transforming him into Neo Dragonoid, and sending him to the human world to get Dan. Then Vestroia starts to collapse without him and all they can do is wait and discuss. After Drago returns to New Vestroia the Perfect Core becomes stable again, they later appeared to send Drago and the others to Earth. The Six Ancient Warriors then battled Zenoheld after he threatened to destroy the Bakugan if they did not come. Although they had the upper hand, the tide of the battle turned quickly after Zenoheld unleashed the Assail System. They were defeated, but before they could lose their attribute energies they transferred their power to the Bakugan Resistance Bakugan, thus giving up their lives. The Six Ancient Warriors' combined power is 3000 Gs, as each of the Legendary Soldiers possesses a G-Power of 500.

The New Soldiers

- Hammer Gorem - Julie Makimoto's Guardian Bakugan and of the Subterra Attribute.
- Preyas - Marucho Marukura's Guardian Bakugan and of the Aquos Attribute. (It is unknown if Angelo or Diablo would be considered one as well.)
The New Vestroia Soldiers
It had been years since Vestroia was saved by the Brawlers. Then disaster strikes again. Alien ships had made land on New Vestroia and conquered it. Although the Bakugan Brawler Resistance was there to save the day, once it had been saved, King Zenoheld had new plans of becoming ruler of everything. The Legendary Soldiers of Vestroia battled Zenoheld and lost so they entrusted their Attribute Energies with the Resistances Bakugan who became the new Guardians of the Attribute Energy. The following are the Resistance's evolved Bakugan:
- Drago (Fusion Dragonoid) - Dan's Guardian and owner of the Pyrus Attribute Energy and the Perfect Core. Drago lost the energy in a battle against Zenoheld, but gained all of the energies after destroying the BT system and then evolved to Helix Dragonoid.
- Master Ingram (and Shadow Wing)- Shun's Guardian and owner of the Ventus Attribute Energy until Ingram lost the energy in a battle against Mylene and Volt.
- Minx Elfin - Marucho's Guardian Bakugan and owner of the Aquos Attribute Energy until Elfin lost the energy in a battle against Shadow Prove and Prince Hydron.
- Magma Wilda - Mira's Guardian Bakugan and owner of the Subterra Attribute Energy until Wilda lost the energy in a battle against Lync and Mylene.
- Knight Percival - Ace's Guardian and owner of the Darkus Attribute Energy until Percival lost it in a battle against Shadow Prove and Lync.
- Saint Nemus - Baron's Guardian Bakugan and owner of the Haos Attribute Energy until Nemus lost the energy in a battle against Prince Hydron.
