What would be Chara’s part to play in this AU. I know that they are probably human like Frisk or a ghost, but if they were human, would it really be that easy to get adopted by the Dreemurs? You said that Frisk was killed many times by Papyrus, so what did Chara do to not get killed? (That is, if Chara was adopted at all)
How did Chara survive? A fortunate turn of events, I'd say. But it's really largely thanks to Asriel and Toriel, respectively lesser Lord of Wrath and Lord of Envy at that time. Officially, Chara was a Human child full of wrath and resentment when they arrived in the Undergroud, and thus the perfect candidate to familiarize Asriel with his future role. Unofficially however, the two children got along very well right away and their friendship was backed up by Toriel who always had a great interest in Humans, and a great deal of fondness for her son and children. Asgore had no choice but to make an exception, but with a few conditions.
Chara was always to stay with one of them or their entourage and was not to interfere with their work. If they broke any of these rules, they would be sent home or executed.
This was a long time ago, before Gaster and Mel were banished, but they all disappeared around the same time. I'll save that story for another ask or post though! If you want more details about them!
