Brass Knuckle: In his female body, Guideau uses a black metal brass knuckle to deliver severe damage to his opponents. Though when Matt Cugat explained that it was behind his "inhuman strength", it is still unknown if it's true.

Cursed Right Arm: As noted by Ashaf and the Order of Magical Resonance, Guideau's Right Arm in the original body is seemingly a extremely powerful Forbidden Instrument. The power in this Right Arm is noted to be potent and Guideau only uses it against particularly powerful opponents that he cannot defeat using the raw power of his original body.
Armored Left Arm: In the fight against the Demon Sword, Guideau uses his left arm in battle as to not completely harm it. Though weak, it still packs massive damage to the opponent.
Deflection: Guideau's armored left arm is able to generate a shield that deflects incoming attacks.

As shown, even the Great Ice Elemental contracted to Matt Cugat is threatened by Guideau's power while in his origin

Guideau is short tempered, impulsive, violent and vindictive. She has a one-track mind most of the time and seem to only care about finding Angela, the witch that cursed her, and exacting her revenge.

However, Guideau is also rather obedient, listening to whatever Ashaf says even if she complains about it. She's rather close with him even though she often threatens to kill him once she get Angela to remove her curse.

Despite how short-tempered and prone to violence she is, Guideau can be caring, as shown when the Forbidden Instrument known as the Nameless Seed was trusted in her care. She, alongside the Cursed Doll, was able to take care of the young boy until the time came to collect him, and when it was time for him to leave, he seemed to want to stay with Guideau, having gotten attached.

Guideau also has 3 piercings on each ear, and she has long fangs. She is dressed quite stylishly and change outfits quite frequently.
