Topaz is a very timid individual, not having very good experiences with people. He's selectively mute, only speaking around people he's comfortable with. He's fluent in sign language and Japanese. His English is very broken. His best friend is Emerald. He's acquainted with Lapis and Ruby. He's shocked to hear a compliment. He passed away from an illness but managed to escape limbo. His right eye is bandaged, as it's actually an orange button. He was a puppet to a sick puppeteer in his afterlife.
