Here are Kim and Kovetri from The Heritage of Humankind. Don't start about backgrounds. Figures drawn in pencil, rest is Paint Shop Pro 7.

The left one is Kimvekadrei Kerriegey and the right one Kovetri Kezghaze. Their family name is Gillian-Garkov. Kim is genderless and has blue-green eyes. Kovetri is a male and has green eyes. They both have black eyeballs, black hair, inverted organ systems and their mutant powers are strong instinctive telepathy, agility, enhanced healing and slight electricity-controlling. They were born on the sixteenth of January in 2089. They're identical twins, but are slightly different due to the mutations.
They're cousins of Kydre and Kinian, of whom there will be a picture in the gallery sooner or later. Their parents Czine Gillian and Gari Garkov were top class research scientists. Czine was an expert on biophysics and cybernetic implants and Gari worked as her assistant.

Don't ask what the icehockey sticks are for. The thing on Kovetri's head is supposed to be a scarf-thing. NOT underpants.
