Twinkle Girl

Since there is little information about this part, I will only say that it is a Buster in the style of the X saga that fires its set of moves by launching projectiles that explode like dazzling fireworks, filling the environment with colorful lights that are hard to miss.

Details of his Armor

Star Fluid: What appears to be an ornament is actually a translucent material, slightly viscous upon contact with humans, extracted from his shoulders, boots, and chest. This fluid flows as a cyan-colored liquid, simulating a starry sky, and powers his body's propulsion systems.

Idol Helmet: Her helmet completely surrounds her face, revealing her blue bangs and a cheerful expression. It features bright red earcups that resemble over-ear headphones, an iconic accessory from the franchise.

Bow-shaped thrusters: The large ornament on its back functions as a system of three-pronged directional fins and thrusters. These allow it to hover, stabilize, and move at high speed across the stage.

Sparkle Pattern: Both her bracelets and the tips of her wide boots are decorated with cross-shaped patterns, mimicking the sparkle of a bright star.

Fun Fact: The style of his boots completely breaks with the traditional style of the Megaman franchise, making it a visual novelty.

Anatomy

For the Classic Megaman saga: he would have a build roughly equivalent to that of an adult

For the Megaman X Saga: it would have the same height as the base model (which is X in this version) but be aesthetically more beautiful

(Since there is no further information about her yet, I will take the liberty and be creative in this regard)

If they go with the lore of Classic Megaman, it would be this:

Being a robot that was originally created and designed as an artist robot and "idol" to the world.

Her immense desire to perform and shine on stage completely spiraled out of control, as her power was the use of fireworks, causing her to lose control explosively. This transformed her into a Robot Master with a dangerous attitude.

If they want to implement it with the Megaman X lore, it would be this:

Being a Reploid who was originally created and designed as an artist Reploid and whose dream has always been to be an "idol", she wants to demonstrate that her artistic style is recognized worldwide through fireworks that she creates herself.

However, due to Sigma's rebellion, she was slightly infected by the Sigma virus during one of her nightly performances, mistakenly attacking humans as well as Reploids, which quickly led to her being categorized as a low-threat Maverick.
