My idea for a Syndra Ultimate skin

Since a lot of people wanted star guardian Syndra (#StarGuardianSyndra2017), and in my opinion a cosmic reaver or a space themed syndra would fit her perfectly due to her being one the strongest champions in game lore wise.

Since two of three ultimate skins have a form switch (Udyr's stance change and Sona's on command switch), Syndra will have one as well, but instead of an on command one like Sona, or an ability trigger one as well. she will have it as the game duration goes on or she gets more and more AP.

Taking inspiration from the life cycle of stars, her skin should transform as the game goes. From a Nebula, to a main sequence star (white), to a red giant (blue in this case just cause it looks better), a red supergiant (again, blue) into a supernova and then a black hole, since there are five transformations, and I'm assuming that 700 AP is realistically achievable without triple fire dragons, baron, meijai's and elder dragon, each transformation will occur every 140 AP.

In terms of body design, her head would consist of her helmet, but on the helmet is the star at its life cycle. At <140 AP, it would be a nebula, at 140-280 AP it would be a small white star, at 280-420 AP a big blue star, 420-560 AP, a bigger and brighter blue star, 560-700 AP a shining white light and >700 AP, its a black hole. Her body will be like cosmic reaver kassadin's blade, except the hue is purple and not blue. Her eyes will just be a bright white.

Her abilities and auto's will also change with the form.

In Nebula stage, her Q will be a purplish dust with white specks in it. When it disappears, the dust will vanish in a poof. Her E will be like spreading Nebula like dust (Think Aurelion Sol's ult in a cone) In the main sequence star stage, her Q will be a dull yellow orb. When it disappears, it collapses on itself. Her E will be like her regular E but yellow. Tether (W) color will change color to yellow. In the Blue giant phase, her Q will be a dull blue star, which collapses on itself when it disappears. Her E will be like cosmic reaver kassadin's E. Her W tether changes color to blue. In the Blue supergiant phase, her Q will be a bright blue star which collapses on itself when it disappears. her E will be like cosmic reaver kassadin's E but brighter. In the supernova stage, her Q will be shining white orb that explodes when it disappears. Her E will be like a like her regular E but a bright white. Her tether also changes color to a bright white. In the black hole stage, her Q is a pure black orb that collapses on itself when it disappears. Her E will be like a like her regular E but a deep black. Her tether changes color to a deep black as well.

Since she a cosmic entity in this skin, she should have voice lines directed towards the Star Guardians, Aurelion Sol, Cosmic Reaver Kassadin, Dark Stars, and Bard and Soraka.
