Yes, this is the same Chaosi that I created on my old account. Just re-imagined and sparkled up with more Photoshop glitter than a Lisa Frank nightmare!

Sonic characters are undeniably fun to draw. Oh my GOODNESS this was a blast to make, playing with pretty, shiny colors and techniques, it's no wonder making Sonic fan characters is so popular! ...rather than try to make a "good" Sonic character, though, I deliberately made the most ridiculously overpowered, unbelievable, groan-inducing Mary Sue I possibly could. Enjoy.

Name: Chaosi
Age: Immortal
Powers: Flight, super speed, super strength, teleportation, telekinesis, energy beams, telepathy, empathy, time travel, shape shifting, elemental magic, prophecy, knitting, tap dancing
Strengths: Loyal, trustworthy, smart, athletic, wise, caring, confident, and has a great sense of humor.
Weaknesses: A little clumsy sometimes, but only when it either doesn't matter at all or it will spark a dramatic plot twist. She has moments of self-doubt and since she's the only one of her kind in the whole universe, she feels very lonely sometimes and like no one will ever truly understand her.
Super Form: She has three:
Super Tenshi Chaosi is her angel version where she gets the ability to heal people and make impenetrable forcefields and raise the dead and eat only one Lays potato chip.
Super Oni Chaosi is her demon version where she gets strong enough to squeeze diamonds out of coal, destroy anything just by looking at it, and even open really tight pickle jars.
Hyper Double-Plus-Good Chaosi is her ultimate form where she has powers from both her angel and demon forms, and in this form, she can destroy planets, alter reality itself, and even beat Chuck Norris.
(She doesn't need the chaos emeralds to transform)
Background: Chaosi is the spirit of the Master Super Emerald (controller for the Super Emeralds in the same way the Master Emerald controls the Chaos Emeralds). She has all of the powers of the chaos emeralds without having to use them, including chaos control, chaos spear, and the ability to use her super forms. She represents the balance of the universe, which is why she has good and evil super versions.
Chaosi was released accidentally by Tails, and when her spirit emerged from the emerald she took on his form. Tails is in love with her but too shy to say anything, Sonic is too, but Chaosi is too nice and sweet to choose between the two, so she just lets them fawn over her, because leading them on and never outright rejecting them is a lot nicer than being honest, right?
Chaosi is kind and sweet and merciful, except when her friends are in danger and then she can kick anyone's ass. In true Mary Sue fashion, her power and abilities change depending on what will make the most dramatic storyline - she can go from helpless vulnerable damsel in distress to badass destroyer of worlds in an instant. That's one of her powers, too.
Special notes: Chaosi found Waldo. ON EVERY PAGE.

(Yes, this deliberately opens up the opportunity for me to have more Photoshop Sparkle fun by drawing her super versions... mua ha ha ha!)
