And here's the reference for Xennah's buddy, Izzy :3
Name: I.S.A.B.E.L.L.E Creation Location: Planet Quartu Story: After Isabelle was created on Planet Quartu, she escaped the factory and took a ship to Planet Kerwan. At the time, Xennah was recovering artefacts and came across her. Isabelle had not seen a lombax before therefore she was unaware of whether or not she was a threat. But when Xennah showed great kindness, she began to talk to her about what had happened previously. Personality: Isabelle is a kind and gentle robot, who enjoys hanging out with Xennah and reading books on mathematics and scientific formulas. Strengths: Mathematics, Quantum Physics and Zoni Abilities Weakness/es: Physical strength (a lot of the time she depends on her Zoni abilities to protect herself and others) and bravery (she occasionally fears those who want to harm robotic/Zoni-like creatures) Fear/s: Altophobia (fear of heights due to an accident she had during her first mission with Xennah, causing Ratchet to rebuild her) Likes: Ratchet, Clank, Xennah, the Galactic Rangers and Grim Dislikes: Qwark and Nefarious
On a bonus note: this is how they look together, as nicely drawn by Lurking-Leanne a few years ago :3 https://imgur.com/a/EoKBr
