Gasterfarm-
Lemon (Sans), he is a dog herd maniac lol. He has a dog, and sometimes cats, shelter! A big one with tons of dogs and even some wolves that got hurt and he healed them. His special ability is making animals sound like they mimic them and it sounds so realistic. He likes to be a menace sometimes lol
He may seem very quiet at first but he is really chatty, jokes around and shares moments with his hundreds of dogs with you! He can often, really often, be seen baby-talking to a big wolf like if it was a puppy. This man knows no fear-
Lime (Papyrus), he is a soil and plant scientist! He studies the soil, its chemical and physical properties and even tests some magic on the soil to try and grow plants faster/stronger/and with some changes. His special ability is a big af memory, full detailed photos, remembering all events within just a day and month. That stuff, he may look crazy but he's really sweet!
Again, he is really sweet but he has a resting bitch face and can seem both crazy and scary since he often talks to himself but he does that to distract his mind, talking about his routine, his brother, his job, etc etc. He will always have something to show you or tell you!
Citron (Gaster), the deceased father of the brothers, that they know of. They don't know who was their mother but the only stuff they know was the diary of Citron, he showed that he truly loved her but never mentioned it.. and they also know that he was a big known farmer between the humans for his wheat and bread.
