Full Name: Nemesis Fury Striker.
Nickname(s): Nemmy.
Other Alias: Once known as Sandra "Sandy" Striker during an extended episode of amnesia and later split personality; the Sandra personality now rarely appears, with Nemesis believing that she has finally "subdued" her.
Age: True age unknown, at least several decades, but cloned as an adult. Nemesis has been accused of being a cranky elderly Pokemon, despite never having to appeared to have aged.
Species: Mewtwo; like all of the Strikers, she has several variations from the original Mewtwo. Nemesis has no extension from the back of her head to her nape and has stronger neck than the first of her kind. She can speak aloud like a human and typically prefers to communicate this way.
Sex: Female. All of the "Striker" Mewtwos were cloned with a sex and genitals - Nemesis later took this to a further extreme and augmented herself with breasts, primarily to impress her lover at the time, a human. Although the relationship did not last, Nemmy enjoyed the change enough to not reverse it.
Marital Status: Single. She was once engaged to a human but later called off the engagement; she now shows no interest in marriage. (Though in one reality, she's definitely with a certain other godly Mewtwo!)
Sexuality: Nemesis has had an exclusively heterosexual sex life thus far, but she would probably consider herself pansexual if she ever took the time to really think about it.
Family: Icy ("mother"; the Mew she was cloned from), Cobalt (Sister), Chrono (Brother), Shiranai (Son). Several other siblings who have since gone missing. She considers a Flareon named Crasher to be her family as well.
Trainer: Steven (Retired).

-- abilities --
All of the Striker Mewtwos were cloned with a "focus," and Nemesis was the classic - psychic power. She is easily the strongest psionic user of her family and, after decades of fighting and focus, she is a force best left unchallenged. Nemesis has reportedly been known to be able to even deflect Dark-based attacks and abilities. She is extremely intelligent and gifted with a love and understanding of science and technology, primarily specializing in cloning.

-- disadvantages --
Nemesis is shorter and much more physically weak than most other Mewtwo; an average human could generally overpower her if her psionics were disabled. Her ability to sympathize with others has suffered over the years and her lack of her compassion hasn't really netted her any new allies outside of the ones she literally creates.

-- personality --
Nemesis is a workaholic scientist - she enjoys tinkering in her lab, experimenting, and above all creating new clones, though these days she tends to only specialize on one or two projects while letting her trusted second, an anthropomorphic Umbreon clone named Maria that she created over a decade ago, run her primary laboratory. She is occasionally mischievous and manipulative but generally means no great harm to others, though she's far from being altruistic. Nemesis generally dislikes humans and avoids contact from outsiders, reacting to perceived threats with outright violence and as well as sadism if she manages to get her paws on them. However, she does seem to truly love her creations and she will go through any length to protect them.

-- other tidbits --

-- Nemesis spends most of her time in a laboratory facility on SkyFire Island, a remote piece of land near the Kanto Region. She relocated/drove off the original inhabiting Pokemon and now all of the inhabitants are her own clones of various species of Pokemon. She has another, much larger laboratory in space, called Migoto, which she generally visits every month or two.

-- She considers herself a trainer as well and keeps a number of clones as her team. The members of the "active" team tend to rotate, but she never switches out Ice Shard, an Articuno clone she rescued.

-- Character originally created sometime in 1997 and still an actively RP'd character!
