Mylene is very cruel and sadistic to the point where she is willing to do whatever it takes to get herself out of a "sticky situation." This is proven when Mira tries to negotiate with her while she is imprisoned in the cage. But she uses her naivety to her advantage, as she uses her Gauntlet's "lightsaber" effect to use Mira as a hostage to get Spectra to show her the Phantom Data. Her attempt to kill Mira during their final battle shows she possesses a bloodthirsty streak. Because of her cruelty, she thinks of Mira and Keith 's attempt to save her from being sucked into Bakugan Interspace as a crazy idea and was very surprised that they tried their best to keep on holding to her.
She was obsessed with power like Spectra Phantom was, going as far to throwing away Bakugan she deemed weak, including Elico. She called Hades as a "pile of junk". She believed that living Bakugan were useless and garbage, seeing them as weapons. She believes Mechanical Bakugans are more powerful than the living Bakugan which is the other way around when her Macubass and Shadow Prove's MAC Spider were destroyed by Helios MK2 and Magma Wilda.
She also developed a heated rivalry with Ace Grit. She also mocked him that he is such a tough guy and even refusing to put her hands on her head.
Though she seems to despise Shadow and thinks of him as a nuisance and even calling him a "freak show," she later realizes that he genuinely cares for her and before vanishing, produced a gentle and real smile as she holds Shadow's hand.
She was extremely loyal to King Zenoheld, and he entrusted her for completing essential tasks. However, she does have morals, as she, like most of the Vexos disagrees with Zenoheld's plan to destroy Vestal and Earth.
In Marucho's Mission, she battled Marucho Marukura and almost won because of her Bakugan Trap Tripod Theta, which used after her Abis Omega, Clawcer and Stug. She then battled Shun Kazami and lost, which was off screen.
Prince Hydron gives her control over the Vexos. She quickly formulates a strategy, by separating the three remaining members of the Resistance and then taking them on one by one. To do that, she has Shadow imitate the voice of Dan Kuso and Mira Fermin to lure Marucho Marukura and Ace Grit. Only Shun realized that it was a trap, but it was too late for the other two members. Mylene then faced off against Ace, defeating him with her new attribute-changing Bakugan, Elico. With her last attack, Ace fell into the water, but could not swim back up. With that, she claimed that "Their nightmare is just beginning."
In Beta City Blues, she battled Baron Leltoy and Dan Kuso in Beta City alongside Shadow Prove but was defeated, and the Dimension Controller was destroyed. She then battles with Shadow again in Gamma City this time against Marucho Marukura and Shun Kazami and still lost the battle to them.
In Saved By the Siren, After Prince Hydron defeated Baron and claimed the Haos energy, she went to retrieve the Darkus energy out of jealousy with her new mechanical Bakugan, Macubass. She would have most likely defeated Ace Grit, but Klaus showed up and helped him to win the battle while remarking that she is indeed beautiful (however coming from Klaus Von Hertzon, that doesn't mean much).
In Earth Invaders, she and Lync Volan went to Earth, and as Mylene stood out in what she was wearing, she tried to find a suitable disguise but ended up sticking out more when her disguise of choice was a white tuxedo for a groom, then they battled Runo Misaki and Mira Fermin and won, taking the Subterra Attribute Energy in the process.
In Virtual Insanity, she and Shadow go back to Earth in search of one of the three Attribute Energies left. They track Billy Gilbert through his gauntlet and follow him to Marucho's house and now know where the Brawlers are hiding. Later when the Brawlers are in the Vexos Motherpalace Mylene, and Volt Luster battle Shun and Baron and they defeat both Brawlers and take the Ventus Attribute Energy.
In Volt's Revolt, Mylene and Volt Luster both show disapproval of Professor Clay's actions. However, Mylene chooses to stay and warns Volt that he'll "Have to look over his shoulder all the time." She wishes him luck after he leaves and calls him "my friend." Later, when Prince Hydron reveals he "took care of Volt" she appeared to be saddened.
In Payback Mylene was ordered by Zenoheld to get the data from the brawlers they need for the Alternative. She later confronted Lync when she told him that they're about to infiltrate the brawlers' base. Lync claimed that He was helping Professor Clay with the Alternative. Mylene, however, feels something suspicious going on. Soon after that, Mylene entered Professor Clay's lab to test Lync's claims about assisting Clay. Then she overhears from Clay that someone made the copy of the Alternative date, and says it was Lync. She tries to find Lync, but he already teleported to Earth before she can catch up to him. Then she reported to Zenoheld about Lync's actions. At the end of the episode, Mylene was seen along with the remaining members of the Vexos after Hydron punished Lync for his betrayal.
In Mylene's Meltdown, she and Shadow infiltrated the brawlers' base to get the data they need for the Alternative Weapon. She reveals that she is now a free agent as she figured that she could not depend on anyone but herself anymore. After capturing Mira Fermin, she and Shadow Prove are led to Bakugan Interspace by Keith Fermin after he tricked them into thinking he was leading them to the Phantom Data. She laments on how weak Spectra Phantom has become (in her eyes), and he tries (and fails) to get her to learn the importance of teamwork. After they were transported, she brawled against Spectra and Mira in Marucho Marukura's Bakugan Interspace along with Shadow once again and lost. After the battle, Spectra tried to reason with her and offered her and Shadow into the Resistance which Mira (even though Mylene had attempted to kill her in cold blood during the battle by having Macubass fire its "Moby Cannon" attack at her when Wilda was temporarily incapacitated) unconditionally agreed to. However, Mylene refused, and she tried to send the Clay siblings to another dimension, but the Bakugan Interspace shut down, and everyone (including Mylene and Shadow) became trapped in it.
In An Heir To Spare, she tries to kill Spectra (Keith Fermin) and his sister Mira Fermin with her Aquos Gauntlet sword, but Keith is able to hold her at bay until Bakugan Interspace started to collapse and Mylene was being sucked in as a result of her setting off a death bomb to banish the Clay siblings. Keith and Mira tried to save her, but she said she would rather die than accept their help. The ground then collapsed under them causing Mylene to slip from them and get pulled in. However, shortly before she was sucked in Shadow pulled her hand and was pulled in along with her. After they were sucked in, Mylene said "that was a really stupid thing to do," to which Shadow Prove replied, "I thought it would be way more fun to travel to the ends of the dimension with my new best friend." Mylene was shocked, possibly because she knew Shadow truly cared for her, and smiled back at him. They were last seen in some dimension still holding on to each other's hand before disappearing.
Bakugan Battle Brawlers: New VestroiaEdit
- Aquos Macubass (Mechanical Guardian) (Destroyed)
- Aquos Elico (Former Guardian Bakugan) (Thrown away) (Deceased)
- Aquos Tripod Theta (Bakugan Trap) (Presumed Deceased)
- Aquos Abis Omega (Former Minor Guardian Bakugan until she met Elico)
- Aquos Fly Beetle (Thrown away)
- Aquos Freezer (Thrown away)
- Aquos Jelldon (Thrown away)
- Aquos Clawcer
- Aquos Stug
- Haos Mega Brontes (Taken from Volt Luster) (Thrown away)
- In a lot of scenes where Mylene brawls on a water surface, she seems to be standing on water, or even flying over it. The anime never points out how she does this, whether it's an ability of hers as an Aquos brawler or some Vestal technology. At some points, Spectra also appears to be able to levitate during some brawls, though he is never seen levitating over water.
- Shadow Prove seems to care for her. Until episode 49, it seemed she didn't return these feelings or at least hid them well enough.
- She and Lena Isis resemble each other; both are blue-haired Aquos-attribute villains who are smart and are good friends with a particular member of their team (Lena with Sid and Mylene with Volt). However, Mylene remained loyal to King Zenoheld, while Lena would eventually side with the Brawlers.
- In the Japanese version, Mira referred to Mylene as the "Greatest Aquos Brawler and Kiss of Death."
- Mylene and Shadow are the only Vexos Members that didn't turn on Zenoheld.
- The English word "farrow" means "a litter of pigs."
Mylene's record suggests she is a good brawler, as she won half of all her battles that have been seen. She is considered the third strongest of the Vexos. However, she and Volt won against Shun and Baron because Professor Clay used the palace to provide extra G-Power for Mechanical Bakugan while lowering the power level for all living Bakugan.
