In the original series, Myaxx was similar in appearance to Vilgax before his encounter with Xylene's ship, to the point where Ben easily confused her with him. However, she had the Chimera Sui Generis mark of beauty on her center tentacle, and was leaner.
In Alien Force, Myaxx has a more feminine appearance, with fewer facial tentacles and a leaner body.
In Omniverse, Myaxx resembles a mix between her two previous appearances. She wears the red armor that she did in the original series, but her tentacles are now much longer and resemble hair.
Myaxx was a coward who would gladly try to run away if she had the chance, however, she was able to overcome her cowardice in order to fight Vilgax's army.
She appears to be aware of her own selfishness, admitting in an argument with Ben that she was "a selfish and self-centered being." However, she showed some concern about the universe being destroyed.
Myaxx originally was working as an assistant for Azmuth. She proved to be devoted to him, helping him in his work on the prototype Omnitrix by collecting DNA from various alien species for the Codon Stream (including the ones for Wildvine and Ghostfreak), as well as creating his hiding place on Xenon.
However, since Azmuth refused to give her the credit she deserved, she eventually walked away from him, and, as revenge for Azmuth's disrespect towards her, erased Azmuth's genetic signature on the Omnitrix and replaced it with her own. She also sold the cloaking technology she and Azmuth developed to hide Xenon to Spheroid pirates, which resulted in her being sent to Incarcecon by the Galactic Enforcers.
Myaxx was introduced in Secret of the Omnitrix, where Ben, Gwen and Tetrax found her on Incarcecon. Confusing her for Vilgax, Perk Upchuck attacked her. After the mistake was cleared, she told them she was the creator of the Omnitrix so they would free her from Incarcecon. Once they had escaped, she told them the truth, but agreed to help them find Azmuth. She also provided Ben with a device that sent the destructive blasts coming from the Omnitrix right back into it, so no one around would be harmed.
On Xenon, Myaxx helped Ben and Tetrax fight Vilgax's army. After Way Big defeated Vilgax, Azmuth offered her to be his assistant again. Though he admitted he wouldn't treat her better than before, she agreed and came back with him, as she preferred not going back to Incarcecon.
