Michiko, Tosh's dragon, fully-grown (though her snout is slightly longer). She is roughly the size of a large dog and eats fish.
Tosh in werewolf form. While she normally only changes at the full moon, strong emotions can also trigger the change.
She sports a number of scars from her encounter with werewolf!T'Pol, but one of the more noticeable scars is actually from when she got shot back home - she was alive and fully healed when she arrived in Bete Noire, but ended up with a distinctive circular scar on her stomach (one that looks suspiciously like she might have been shot there).
