Name: Kosmo Roma Mazzotta

Age: 20

Gender: Female (genderfluid)

Species: Demon

Sexuality: Pansexual

Personality: The first thing to know about Kosmo's personality, is that it's very split personality. One moment she could be emotionless and cold, the neck she could be forcing you against a tree with a knife to your throat, a smirk on her lips as a dangerous look formed in her eyes. To put it simply, she's depressed, anxious and extremely insane. Because of her split personality, she is VERY untrustworthy. She appears to be quite a harsh and cold hearted woman, pushing away all positive thoughts that she may feel. Some call her manipulative and insane, which is extremely true the main thing she is, is power hungry. She seems like she'll never stop wrecking havoc until she gets what she wants...

Soul colour: a third cyan and royal blue stripes/megalomaniac, a third black/hate and a third red/determination

Looks: Kosmo, surprisingly, doesn't look much like her undertale counterpart. She has quite tanned skin and soft, brown hair which occasionally has a streak of red in it from blood, or white from the dust. Her eyes are a soft hazel instead of red, confusing but true. She has no mask, her face having healed. Her jaw still doesn't work properly, resulting in her voice crackling every now and then. She wears a simply black dress and leggings, dress boots on her feet. To top her outfit off, she wears black and purple eyeshadow, mascara, and red lipstick.

Backstory: Kosmo's au was once the normal au. Everyone was happy, playing family. Perhaps that's why she snapped, not wanting to play happy family anymore? Perhaps her suicidal thoughts and depression? We don't know, all we know is that she controlled User to kill and use the reset. Rachel stopped her before she even got close, forcing the demon to the back of the creators mind. This aggravated the demon, a burning need for power and control forming inside of her. She broke free from User's mind and escaped, brutally killing both her and Chara. Before Rachel could escape, however, she forcefully connected her soul with the angel. She forced the angel to watch as she killed everyone, seeming to laugh at their screams. Rachel tries to stop her st first, eventually giving up. She couldn't stop Mentality; she was too strong. The au turned to shambles, and no one escaped.. that's what they thought anyway.. there is a belief where the aus Insanity and Sans escaped, but that's for another time. Mentality changed her name to Kosmo, forcing Rachel to change her name. The angel chose Delaney. The au was all dusty, destroyed, hopeless. Kosmo was glad about that. From then on, she killed anyone who stood in her way for power or came into her au. That'd teach everyone for ignoring her...

Other: - Demontale Mentality
- Had major depression, schizophrenia, anxiety
- Is a bit pychotic
- Major sadist and is secretly a massive masochist

- 260 HP, 70 ATTACK, 50 DEFENCE
- Has a mood necklace, which she has blessed herself. This necklace quickly drowns anyones HP who wears it other than Kosmo, killing them in less than 20 seconds
- She forces her Rachel, renamed as Delaney, into her mind until they're alone. This is when she abuses the angel close to death before forcing her back into her mind so she could heal before the next round of abuse. This happens about three times a day and is always a mix of either torture, mental/emotional pain, and sexual abuse

- Turn offs: Safewords, multiple penetration, foodplay, DDLG/DDLB, gentle
- Seceretly loves being called gentler nicknames and people being soft eith her

1. You walk into an au you don't know all that well. To be honest, no one did. This au had been abandoned for a LONG time. You were only here because you got lost trying to find Mentality who just suddenly disappeared.. You walked through the woods and saw.. Rachel? No, this wasn't your Rachel, but a different one. She ran into you, a small whimper exiting her mouth. "I'm sorry... so sorry..." she whispered, staring at you before shaking her head. "You shouldn't be here... you need to go, now..." she whispered, gaze casting to where she ran from. "Delaney!? Where the FUCK have you gone? Wanna play hide and seek or something~?" A voice growled, a chuckling exiting their mouth as 'Delaney' grabbed your hand. "If you're looking for your Mentality, I'll take you to them. We have to be quick or... SHE will find us..." she muttered, grasping your hand. "Please.. you can trust me.."
