(Alright,So last time here we focused on the forms of a certain black hedgehog faunus and the older brother Turbo Salazar,That being Nitro and his transformation list along with a technique,For this round we'll be focusing on the different transformations of the younger sister of Zeke Muto and the guardian of the spirit of the Rainbow Dragon,Kara Muto,and this will be a list of the transformations that she has along with some that she will end up with later on)

Starburst Rainbow Guardian (Pretend that her dragon wings and tail appear) (This would be Kara's first transformation among with being for when she first had bonded and united with Rainbow Dragon when she first became a Duel Spirit Guardian,This form gives her the ability flight along with it increasing her speed and velocity to faster rate than in her base form and also increases her strength by 55%,altough considering that this is her first form,A portion of Rainbow's other powers and abilities during their spirit unity is blocked off from her)

Cryatalix Mode (Crystalix would be Kara's second transformation with the spirit of the Rainbow Dragon along this being one of her more favorited forms that she likes to use as this is the one she tends to use more often,This form gives her access to a bit of a much wider portion of her power and soul energy and/or Ki or Furyoku from Rainbow and other Duel Spirits such as the other Crystal Beasts,This form also gives her more stable control of her energy weapons along with it increasing her flight speed even more with it being able to reach up to at least Mach 4)

Black Crystalix (Rainbow Dark Dragon) (Black Crystalix is Kara's third transformation and is on a similar league as her original Crystalix form when comes down to her speed and strength however,Black Crystalix is also at a higher level of power and soul energy than it's original counterpart as this form came as a result of Rainbow Dragon's corruption from a wicked and corrupted Duel Monster by the name of Yubel a few years back in the past while the other half of the form is fueled by a very strong feeling of anger and sometimes even possible hatred within Kara that she may have towards some of her and her friends adversaries for something absolutely terrible or brutal to either  one of her friends,family or to innocent people as well as her home city or kingdom,making Kara and Rainbow a little more aggressive and even relentless than their normal selves would ever be and she also uses more darker versions of her original abilities as well as her being able to use invisibility in this form for stealth however she can only stat invisible for at least up 4 minutes with it taking up to 7-10 minutes for her to be able to use it again

Malefic Rainbow Dragon Form-Crystalix Automata (Crystalix Automata is the fourth transformation that Kara has in her list of multiple evolutions with this one being her strongest one up to this point as it increases her soul energy and power up to 75% with her speed being brought up to Mach 5-7 and also gaining the ability of Aether [Also known as Quintessence ] as well as the ability control the powers of both her light and dark all at once within in this form as she can combined to create stronger attacks as well as this also improving her reflexes when trying to evade the attacks of enemies or dangerous obstacles that stand in her way,But this requires to also gather energy from either power crystals,A high amount of soul energy from a deceased dragon spirit or even some power from using either a Chaos/Super Emerald,shard of Vibranium,Red Kryptonite or an Infinity Stone in order to sustain herself in this form for a longer period of time since she hasn't fully mastered it yet)

(For now this would be all of the forms that Kara has unlocked or is planned to have eventually that she is going to unlock in near future that I can think of right now but I am thinking of adding a few more later on but I need to think of how to get them work as well and when to have them introduced)
