A time-traveler and the saviour of the future, he's a hedgehog with hope and determination to save what he has left. While he's stoic (sometimes oblivious) and focused on his personal mission, he's learned to help those along the way. Even if he get's sidetracked. The isolation has made him feel like he doesn't need any help, that he doesn't need to rely on anyone.

Though, maybe he can let loose and be himself every now and then. He doesn't always have to be this tense, does he?
