Perfecti

Perfecti (Kanzensha in Japan) is the ultimate form of the series' major antagonist, Mycale. This form was originally non-playable palette swap of her "base" form in Akatsuki Blitzkampf, prior becoming its own character in ''Ausf. Achse update, and also the current form which Mycale use as of En-Eins Perfektewelt''.

Appearance
Prior to ''Ausf. Achse'', Mycale's modern-day Perfecti form was just an NPC palette swap for her "base"/Kati-possessed form, commonly known as "semi-perfect" palette swap form.

Canonically, after possessing Anonym Merel Lambuth, Mycale begin to have all of her current host's appearance, and immediately wears a long skirt, dictator visor cap (with Perfecti crest on the upper center of the front cap), and sleeved uniform as her modern-day outfit, while still retaining her signature Perfecti cape. She can be sometimes seen wearing a long hooded black cloak, discarding it before entering battle. In this form, she somehow can summon a chair while mostly crouching or on her round victory animations.

The known default color palettes which Mycale's modern-day Perfecti form sports are: white hair, red eyes, and both black wardrobes (also has red inner cape as her previous host's appearance). In En-Eins Perfektewelt, her wardrobes changes to white (excluding the cape, her uniform's wrist and the front cap).

Akatsuki Prototyp Nr. 1/Blitzkampf (Ausf. Achse)
After being separate from Kati by Anonym Merel Lambuth during one of the opposers' raid on Gesellschaft's base, Anonym Merel took Mycale's staff, Gríðarvölr to confiscate it. However, Mycale's spirit, which link to her staff immediately possess Anonym Merel few seconds later, and somehow found the body too perfect and Merel has darker sides in mind, allowing Mycale uses corrupted Holy Spell to create her own uniform and allows to evolve Gríðarvölr into its ultimate weapon, Dáinsleif.

After Akatsuki kills Murakumo, and presumably rescues En-Eins somehow, Mycale permanently possess Merel's body to hide from the Holy Club who are looking for Merel, while at a same time the witch took over the leadership of Gesellschaft for her upcoming sinister plot.

En-Eins Perfektewelt
Mycale uses Merel's body as a hostage while declaring a war on humanity ten years later in few months after discovering a collapse accident in the undeveloped Tibetan Tsampo Canyon.

Gameplay

BlazBlue: Cross Tag Battle
Mycale's Perfecti form and most characters represented their home series are datamined in the crossover BlazBlue: Cross Tag Battle Season 1.5, and becoming one of the potential DLC candidates after the initial full Season 2 release.

With Kati's placeholder included as well, this may also evident that Mycale would go under her Perfecti form, similar to BlazBlue characters Noel Vermillion (under her Base form), Tsubaki Yayoi (under her Izayoi form) and Yuki Terumi (under his true Susano'o form) (except Hakumen, due to being alternate timeline Jin Kisaragi).

Trivia

 * By the time after Ausf. Acshe update of Akatsuki Blitzkampf where Mycale's Perfecti becoming a separate character than her "base" form, Mycale's Perfecti form can only be fought in post-Round 1 after her base form being defeated, just like Adler to Elektrosoldat
 * The victory and story portrait of Mycale's Perfecti form is reused from her character select portrait in Akatsuki Blitzkampf Ausf. Achse.
 * To make it even obvious since her host was Kati in Akatsuki-related titles, they share a same Japanese voice actor as of En-Eins Perfektewelt.
