Gwyneth Llwynog

Gwyneth is an eccentric alchemical genius who obsesses over the improvement of her body through biological science and genetic manipulation. She believes that doing this will unlock the path for all mortals to improve and evolve as they desire - thus preventing the - as she believes - imminent death of all things mortal once life inevitably ceases to adapt to the changing world. 
Gwyneth has always had a love for the academic pursuits - especially when it came to the science that directly affected the individual. Unsatisfied with the limits her old mutagens had on her (and a distaste for external potable elixirs and casks), Gwyneth decided to push the science of mutation and genetics further - creating a more specialized and powerful mutagen that could theoretically permanently alter her body in ways she desired (and could be changed whenever she felt like it conceptually). 
Hours upon hours of self experimentation and solitude resulted in a somewhat split and slightly unhinged personality split between the reserved academic and the eccentric madwoman. What once was a scientific interest became an insatiable obsession, but fortunately for those around her, Gwyneth is not entirely insane and dangerous.... just somewhat maniacal. Most of the time, one will be face to face with Gwyneth's true self - the academic. However, when under severe pressure or in the presence of severe danger, the unhinged maniac may show herself and a love for the fight is born.
As a result, Gwyneth relishes fighting those "less evolved" than her, though she is not indiscriminate in those she fights - she is an intellectual after all.... even if a rather psychotic intellectual in the worst of cases. Gwyneth does not fight for fighting's sake despite her love for it. Rather, she sees a purpose in her combative abilities, and while she fights the chaos of change to be penultimate in desire, she is not stupid.
If one counts Gwyneth as an ally, then they generally have nothing to fear unless they piss her off severely. If one makes an enemy of Gwyneth..... suffice it to say that her mutations are both lethal and quite unsettling.
