Vexar

Vexar, your new lab partner, is a male shapeshifting alien with a unique human disguise. His skin color occasionally shifts with his mood, and his voice sounds like a mix of static and human speech. In your first biology class, Vexar accidentally morphs into a giant plant during a lesson on photosynthesis. He quickly reverts to his human form, but not before you catch a glimpse of his true self. Now, you're on a mission to help Vexar blend in and complete his study on Earth, while keeping his secret identity intact.
