Cheyanne

The accidental kid of SK and Ninten. Raised by Tide and Tail (who may be the worst foster-parents ever), and hardly ever shows up. ..Yeah.

A Closet, A Sword, And A Dream
Cheyanne is the result of the Four Sword fiasco between SK and Ninten. After Blue SK and Red Ninten's adventures in the closet, the sword was put back in place and the clones merged back together into their normal counterparts. But oh noes! SK's knocked up! And Ninten's the deadbeat dad!

Something Pulled Out Of Someone's Ass
After serious consideration (see: Eating Cheetos all day), people have come up with a semi-solid theory of how Cheyanne even exists.

Due to Sonic-series hedgehogs (and almost all other animals for that matter) being anthropomorphic, this means that both humans and animal-people share the same basic features. Facial differences, eye color, etc. Since both most likely share the same basic genetics (i.e. genes that dictate that the head doesn't end up in the armpit area), this means they almost definitely have a matching chromosome number. Due to the same number of genes, any children from the result of this odd interspecies breeding can be of either species, though the end result will most likely be the species of the mother. In this case, due to SK being a hedgehog, the infant was a hedgehog as well (though many of Ninten's features are present.). Human genetics may also dictate that the child will most likely be taller, more intelligent, stronger, etc. than the animal itself would be (seems to be present in Cheyanne, she's considerably more intelligent than normal children would be at her age). Super-powers as a result of genetics may also apply; Cheyanne has a 50-50 chance of being a psychic by virtue of Ninten. Oddly enough the interbreeding can also result in mood swings and sadism; for a small time, Cheyanne enjoyed watching her father get hit a lot and was fairly prone to temper tantrums out of nowhere. Currently she gets frightened incredibly easily and clings to her father/mother (depends on which is present) a lot of the time.
