12
[LEVEL: ???. HP: 120. ATTACK: 40. DEFENSE: 200.] Chara Dreemurr, the 7th fallen human that's currently in hiding, being hidden (illegally and without king Sans's Knowledge) by her adopted family. her mother Toriel, the goat monster who's leader of the royal guard. her father Asgore, goat monster who's the royal scientist. and her brother Asriel... the goat monster who wants to be in the royal guard by capturing a human (a human that's not Chara) she can stare inro your soul and see your sins... despite being a human herself, she hates humans for what they did to Monsterkind. extremely lazy, she lives with her brother Asriel, loves puns, secretive, uses whoopee cushion's to prank people. she knows about your control over the timeline, and he remembers every time you RESET the timeline... how? simple... before you had the power of determination, Chara had it. She knows whenever you use your SAVE and LOAD abilities to save your place like a video game, because before you showed up, She could do the same thing. she knows that he can't stop you, because your determination is stronger than hers, and therefore overrides it... she hides this Knowlage because in her own words, "-Because even i reset, you reset, or some other human resets, Toriel, Asgore, Asriel, everyone... they're all just gonna wake up with no memory of it, right? to be honest it makes it kinda gard to give it my all... that's why imI used my ability SECRETLY and RESPONSIBILY, unlike you, kid.", she's completely given up on living normally, occasionally dropping hints about her knowledge about your abilities, and her use of those abilities before you... all she can do is hope that you use that power for good but because you're a human, she doubts that you will...
P.s... She's a chocolate addict, and can't get enough of it.
