Ratchet
9. Do animals like them? Do they get on well with animals?
He likes cats, and has one in Medietas. Took care of Zoe's cat while she was gone, much to the dismay of Cat. I imagine he's intriguing to animals, though they shy from him if he smells fresh from the clinic.

10. Do they like children? Do children like them? Do they have or want any children? What would they be like as a parent? Or as a godparent/babysitter/ect?
Ratchet adores kids. He doesn't want any of his own in game because well, he has some body horror about the whole process. And I headcanon back in the early days of the war, he was part of the creches to help raise new Cybertronians. He's a fab babysitter per Splendid & Annie

11. Do they have any special diet requirements? Are they a vegetarian? Vegan? Have any allergies?
Was omnivore, now vegetarian who eats fish that's ready to cook too. Drinks milk, eats eggs. But no thank you on meat. Maybe chicken if it's already prepared. He had to deal with burned bodies during the Disappearances.

12. What is their favourite food?
Coffee. Likes pasta dishes and cake.

13. What is their least favourite food?
BBQ/grilled meat. Used to love it but now: No, thank you.
