Don't think you're special just because you were given an Attribute Energy by the ancients!
—Helios' first words in Spectra Rises

Helios MK2 (ヘリオスMKⅡ, Heriosu MK II?) is a Cyborg (half-mechanical) Bakugan and Spectra Phantom's current Pyrus Bakugan. He unnaturally evolved from Cyborg Helios (offscreen) in the second arc of Bakugan Battle Brawlers: New Vestroia in his and Spectra's attempts to make him into the ultimate Bakugan. Sometime between New Vestroia and Mechtanium Surge, he evolved into Darkus Infinity Helios.



Helios was upgraded with new mechanical parts to try to make him the Ultimate Bakugan. As Drago noted, his evolution was not natural. In this new form, Helios is much stronger, with more highly advanced weapons. For example, he now has one fully mechanical rocket arm that detaches, and fires lasers and reveals a cannon on Helios' arm that shoots lasers too, but this feature can be only activated by activating the ability Dragon Pounce. Helios no longer has a spinning ring in his chest, it was replaced by a hidden chest laser that can be activated by the ability Ragnarok Cannon. His mechanical eye is now more advanced now, as it resembles a multi-celled lens instead of a camera lens. He also can combine with Fencer, Scraper, Spindle, Foxbat, Leefram, and Klawgor to form Maxus Helios MK2. He was later upgraded with fewer spikes and has human hands instead of claw hands. He can now be equipped with Twin Destructor and Zukanator. He hated Drago, but after losing his last battle to him he admits Drago is the Ultimate Bakugan.

Ball Form

In both the original and Battle Gear-compatible version, Helios MK2 opens up similarly to Aluze and its hidden chest laser in ball form can be seen. In this form, it more resembles Viper Helios.

Helios MK2's ball form first appears in the anime in its original version. Its arms, with three-fingered claws, are placed on the back. The Battle Gear-compatible version of Helios MK2's toy is simply a slightly modified version of the original, whereas after he gains the ability to use Battle Gear in the anime, his ball form completely changes, giving him side wings that open from the outside instead of the inside, opening arms, and different designs on the wings.

Helios MK2's ball form is later changed in the anime. Its wings fold down to allow Twin Destructor and Zukanator to attach to him. Its arms are placed at the side of the main body instead of on the back, with human-like hands instead of claw-shaped hands in original version. The structure of the wings and some details are also changed compared with original version. Whenever he stands after being rolled a ring of fire and magma appears around him.

Bakugan: New Vestroia


He made his first appearance in Spectra Rises, where Helios MK2 battled Cross Dragonoid, Magma Wilda and Minx Elfin. He first fought Drago one on one before Wilda and Elfin came to help Drago causing him to lose round 1. In the next round managed to defeat the last two with Chaos Boost Cannon but Drago survived, he then became Maxus Helios MK2 to battle Maxus Cross Dragonoid and ended up losing.

In All Or Nothing, Helios MK2 fought Cross Dragonoid again, because Dan wanted to know where the Vexos Mother Palace was and Spectra was the only one who knows where it is. In round 1 Helios beats up Drago, but Drago comes back by using his power. In round 2 Drago wins by telling Helios he isn't worthy to be the strongest. Drago wins the brawl and Spectra takes them to the Mother Palace.

Once in the Mother palace in BT: The Final Battle, he helped Cross Dragonoid and Magma Wilda battle Farbros and Dryoid. Somehow earlier, he had received an upgrade to be able to connect with Battle Gear. Even with the power of Helios plus the Battle Gear Twin Destructor, they lost, but in the process destroyed Farbros and damaged Dryoid.

In spite of the Battle Brawlers' efforts, the Bakugan Termination System was activated, in Exodus, Helios MK2 and Cross Dragonoid went to New Vestroia to destroy the BT System. Unfortunately, neither of their attacks worked, so Drago flew to the atmosphere with the BT System. The BT System was destroyed and Drago absorbed all the attribute energies. After the destruction of the BT System, Helios and Spectra left the Brawlers on New Vestroia.

With the Vexos out the way, Helios confronted Helix Dragonoid for one last battle in Spectra's Last Stand. In the end, Helios loses, and in his broken state, he accepted Drago as the Ultimate Bakugan, abandoning his evil ways and permanently sided with the Resistance, just as Masquerade and Alpha Hydranoid joined the Brawlers. Later on, he and Keith Fermin help Drago make his own Battle Gear: JetKor.

In Mylene's Meltdown, He is shown telling Spectra to not let Shadow bother him and saying they can take him. When Spectra and Mira trap Mylene and Shadow in Bakugan Interspace, he battled against Shadow Prove's MAC Spider while Wilda brawled Macubass. Shadow opens his gate card Phantasm which freezes Helios in place. Mac Spider uses Spider cannon which causes no damage to Helios thanks to using Farbas RX. All the damage to Helios before gets removed. Helios then moves towards Mac Spider and the Spider uses Tarantula Needle which causes no damage. Mac Spider then uses Blaster Needle causing Helios to taunt him and ask Shadow if that was all he had. Mac Spider then traps Helios using Spider net. Helios gets stuck in the web causing Shadow to use Mega Terror Impact to defeat Helios quickly. Unfortunately for him, this leaves MAC Spider prone to attack and Helios capitalizes, using Blackout Cannon to blast a hole through MAC Spider's frame and destroy it entirely. Helios then taunts Shadow saying MAC Spider is now gutless. He also appears to be a lot calmer now and was willing to help out Magma Wilda defeat Mylene Farrow's Macubass and saved his sister Mira Fermin from getting blasted by Macubass by using Ragnarok cannon to block Moby Finale. Helios asks if he can finish off Macubass, Wilda says he is ready to finish Mylene off. Before backing out Helios tells Wilda to leave him in peace's which Wilda does after beating Macubass for good.

In An Heir To Spare, he escapes from Bakugan Interspace thanks to Marucho along with Mira, Keith and Magma Wilda, but Mylene and Shadow get sucked by the portal and live their life in another universe.

In Ultimate Weapon, It is shown that he still maintains a serious minded fighter mentality, as shown by his annoyance at Runo and Julie's girlish antics during the party thrown by the Brawlers to celebrate him and Keith joining the Resistance. When the team all goes to bed he notices Keith not sleeping and asks him what is wrong. He tells him that Clay Fermin must be stopped. Helios says he will when they hit the palace tomorrow. Spectra then says tomorrow will not come sooner as he puts his mask on and ambushes the palace at night. After arriving, he battled King Zenoheld and Farbros for a second time. During the battle, he was able to damage Farbros, and, together with Rex Vulcan, held their ground against Assail Farbros, thus making him the second Bakugan (after Hydron's Dryoid) that won against Farbros.

In All for One, he teamed up with the other Brawler's Bakugan and battled Zenoheld and his Alternative Weapon. He also used his Twin Destructor briefly before replacing it with Zukanator, which was able to generate enough fire power to blow a hole through the Alternative's hull, allowing him and Wilda to invade it from the inside.

In Final Fury, he takes Wilda on his back out of the Alternative. After the Alternative was destroyed, he bids farewell to Drago and says that they will meet again and hoped they would still be on the same side. Together with the rest of the Vestals and their Bakugan, they return to their home planet.

Unlike other mechanical Bakugan, Helios MK2 has only one weakness:

  • FARBAS EM will not work against very powerful abilities like Helix Dragonoid's ability Galactic Dragon. Helios will automatically lose the battle because of his safety protocols. This was shown in Bakugan: New Vestroia episode 44, until round 2, when Helios removed his safety circuits, so it is highly unlikely he still had that weakness. In addition to that, his Power Level slightly increased, and was able to nullify Dan's Gate Card with brute strength alone.

Physical Game

Helios MK2 is exclusive to Japan. It was first released in Japan on October 8, 2010 in Pyrus in Entry Value Pack. It was later released in Pyrus (black as main color), Aquos, Ventus, and Darkus in Japanese Starter Pack: Evolution Kit 2 (BBT-07). These versions are all non-Battle Gear Compatible. Its G-Power in Pyrus in the BBT-04 Entry Value Pack, which has silver as its main color, is 540 Gs. The Darkus from the BBT-07 Special Evolution Pack C has 520 G.

As of January 8, 2011, a Battle Gear Compatible Version of Helios MK2 was released with the catalog number of CS-001. Its G-Powers are 520, 540, or 560 Helios MK2 (Battle Gear Compatible-anime version upgraded) is exclusive to Japan. The Battle Gear Compatible Version was reissued as a rare find in the BCV-1.5 booster packs.


  • Helios comes from Greek mythology, from a titan who personified the Sun.
  • Darkus Helios MK2 is in Bakugan: Gundalian Invaders Darkus color scheme that is black, green, and yellow.
  • Helios MK2 is the first non-Gundalian Invaders Bakugan that can connect with Bakugan Battle Gear and the only one who does not appear in the aforementioned season.
  • He is the only Bakugan to change ball form, even slightly, without going through an evolution.
    • This excludes BakuMutants, whose ball forms temporarily change when they mutate.
  • He has double-jointed legs like Contestir, Titanium Dragonoid, Aranaut, and Cross Dragonoid.
  • The molds for regular and Battle Gear compatible versions of Helios MK2 are basically identical. However, the Battle Gear version is missing the springs that keep its wings from instantly falling down. This can easily be seen by looking at the back of the closed marbles.
    • This is not the case with the anime, in which his ball form changed significantly when he was made compatible with Battle Gear. Changes include the designs on his wings, the flaps in his wings opening from the outside instead of the inside, and the addition of separately opening arms.
  • Helios MK2 is the only Bakugan that broke a Gate Card with sheer force alone in the anime.
