Lizzie (full-name Elizabeth Nyux) was just over a year old when June happened upon him in Oppo's bar, saving the reptile in time from becoming the Arcno's lunch, and the two have been close companions ever since.
A very lazy, little lizard, who prefers to spend most of his time basking under his heat lamps and eating, Lizzie would be most similar to a present-day earth Iguana. At two years old, Lizzie is currently a juvenile and will be a fully grown adult in about another year.
Spoilt and well-loved, he has his own enclosure/area in June's room where he spends most of his time, though June will often take him for walks around the ship to get some exercise and run about.
His diet consists mostly of nutritious pellets and freeze-dried insects, though his favourite thing to eat is fresh bugs, which June manages to pick up whenever they're back on Teranium.
Among the crew, Lizzie is pretty popular. The rule whenever Lizzie he leaves the room is that he has to visit with Aya, who absolutely loves him, though Lizzie always prefers to see Cal (who doesn't love him so much... or so he says).
When the occasion calls for it, Lizzie can be frighteningly speedy, zooming along the corridors of the ship. He has many little quirks, including a strange obsession with shoes. He likes to chew on them, hide in them, and just generally drag them around the place.
June suspects this is why the lizard is always going after Bash, because he particularly loves his bright sneakers, though Bash disagrees, arguing that the fact that Lizzie has bitten him multiple times and chews on the cables down in the docks proves otherwise. Lizzie is now banned from going anywhere near Bash's work area (and not to mention his bedroom) and Bash manages to avoid him most of the time.
Overall, Lizzie has been a great source of companionship and comfort to June, who loves his little buddy very much. In-game, you'll find there are many benefits to being kind to Lizzie, including deepening your friendship/relationship with June.
