A simplified reference for Keira-Jo's updated design.

Name: Keira-Jo.
Nicknames: Kei-chan, Babe or just Kei (from Evil Sonic).
Gender: Female.
Species: Mobian Echidna.
Age: At the introduction of my fan-fics, she is 18...at the time of her death in my fan-fics she is 35.
Fur color: Reddish-brown.
Hair color: Originally was brown, but has been dyed purple-pink (the dye is what makes it spiked).
Powers/Abilities: Has a natural ability to enhance the powers of those she is around (but is unaware of this fact, Evil Sonic knows and initially wants to use her to increase his own powers...).
Personality: Though it is not revealed until later, she has a split personality because of her rocky childhood in-and-out of foster homes. Mostly people only see "Keira-Jo", a teasing, taunting, flirtacious woman with a slight bit of a mean side...she also has a hidden personality that Evil Sonic refers to as "Kei", this personality is shy and loving.
Biography: A petty thief of some fairly good skill, she emerges from a stint in jail a short time after Echidnapolis comes back into the Mobian modern world. A little bit after she tries starting a job, she encounters Evil Sonic for the first time and goes off on an adventure with him, where at the end she realizes she fell in love with the dark Hedgehog from an alternate Mobius. After a couple years, she is kidnapped by a sorceror from Downunda named "Enzo Larak" (a Lizard)--who, in the end, it turns out had crossed the dimentions and teamed up with the Echidna, Remington (we'll refer to him as "Dark Remington") from Evil Sonic's Mobius. Evil Sonic was pretty annoyed at this...and at Julie-Su and Knuckles urging him to chase after Keira-Jo and rescue "his princess"...but wound up doing it anyways, because he actually had fallen in love with her. After saving her, Evil Sonic took them to an "empty Mobius" he had found...there were no people there anymore, though it seemed there was no devastating crisis that destroyed everyone either (it was as if all civilization had simply disappeared from that world one day). There they lived for about 15 years, raising a daughter, Kara-Li. Unfortunately, Larak and Dark Remington eventually found that Mobius...took Keira-Jo away...leading Evil Sonic and Kara-Li on a search through Mobius' alternate versions, until eventually landing on Mobius Prime during Guardian Jeison's wedding day. Keira-Jo sacrificed her life to save Evil Sonic from Dark Remington...the event left Evil Sonic badly injured (both physically and emotionally) and let Kara-Li get corrupted by the shattered Chaos Emeralds that once possessed Dimitri and made him Enerjak.

Keira-Jo is my own Sonic OC and belongs to me.
