Name: Sidney Gibken (ha ha Sid2)
General appearance: Fluffy hair, casual Earth-wear, with a lot of red mixed in. Looks like a pretty normal teenager, really, he doesn't get a cool coat when he doesn't even have a ship. The same height as his folks, lithe, built more like Joe
Personality: Excitable, energetic, do-it-now-think-never. Bratty, though without being spoiled? That "I want it and I don't care so long as I get it" type, I guess... ? Typical baby of the family. Things aren't handed to him, anyway. Dislikes being babysat even though it is completely necessary all the time, since he doesn't stop once he gets started on things (like running). Optimistic, at least! He cares a lot about his extended messy family, he just hates being the baby who needs watching over. So... a Red.
Special talents: Running into walls... He's pretty good at fighting, though his weaknesses hold him back from being the best at any of it.
Who they like better: Uh aniki. The answer is aniki. Because adults and rules and aniki doesn't count as an adult yet.
Who they take after more: Marvelous, to everyone's deep chagrin.
Personal headcanon: When he was a year old he cried for a week because Joe would only use his full name on him.
Face claim: Murai Ryouta because that is what I was given, and I never bothered to change.
