Cassis

**Cassis** is a non canonical child of Reaper!Sans and Underswap!Sans, and were made by **Pepper-Mint** on Tumblr.

Despite having been known to be an offspring of the two, Cassis was not biologically made by them. Instead, Cassis was created through the fusing of both Reaper and Blue’s SOULs. Therefore, it’s more accurate to call Cassis a fusion of Reaper and Blue, rather than being called their child.

## Profile

### Appearance

Cassis is a young, male monster with the physiology of a skeleton. He has star-shaped pupils that float in the center of his eye sockets; the left one being blue, and the right one just being white. If he’s ever to blush for some apparent reason, his face would be shaded with a blue tint.

Cassis’s out mainly consists of a black hood outlined with light blue on the inside, with the bottom of the hood having a horizontal blue line that runs all the way to the very back; with a small triangle being cut out and displayed with a blue star on top. He’ll additionally wear a blue scarf with lighter linings on the middle that form a ‘V’ shape. The scarf can often be seen wrapped around the neck-line of his hood and topped with a gray star.

The black cloak he has is adorned with an intricate blue pattern, and the opening of the cloak having a blue outline with a few buttons. Underneath his cloak, he wears a dark shirt accented with a few light blue outlines, gray pants, and dull turquoise boots.

Cassis can occasionally transform himself into a crow (an ability that somewhat stemmed from Reaper), along with being able to summon wings. The wings themselves have a base color of black, and are outlined with blue.

### Personality

Initially, due to Cassis being a fusion of Reaper and Blue, the two predecessors were sometimes able to take control of the body and, therefore, had a combination of both their personality traits. Over time, however, as Cassis began to make relationships with other beings, they decided to let go of their influence on Cassis, and let them live their own life the way they wanted to.

Cassis, in general, can be really energetic and enthusiastic around others, being exceptionally friendly and social towards people. Though, he can also be quite lazy at times, and it’s a common occurrence for their energy to quickly be drained. While he’s normally happy and carefree, he can also go dark from time to time. Whenever he’s wanting to be left alone for a while, it’s usually because of him getting flashbacks to past memories (probably the memories from Reaper!Sans) or just being melancholic in general.

### Abilities

Cassis can’t kill people, but can see an aura around them, whose color depends if they’re almost ready to die. He’s able to take someone’s soulf if they’re already dead too. Cassis is able to put people to sleep or make them sick by touching them if he concentrates enough magic.

* **Aura Detection**: Cassis has the ability to see auras around the living entities near them. The colors the entity may emit through their aura depends on how close they are to dying.
* **SOUL Manipulation**: Cassis is capable of putting people to sleep, or make them sick by just touching them if he concentrates enough of his magic on them. This ability is similar to how Reaper!Sans reaps his victims. He’s also able to take the SOULs of those who have died.

Besides that, he can fuse Reaper and Blue’s weapons into one sword, knife or an spear. He mostly uses the spear just because he thinks it’s cool! Other weapons include Gaster Blasters and chains.

## Backstory

### Prior to Fusing

Reaper and Blueberry fell in love after having some time knowing each other. The gods told Reaper he shouldn’t do it since he could end killing Blueberry by accident, but he didn’t care. It was like those stories of forbidden love the humans always made.

At first, they were fine with having a relationship whithout kisses, but soon Reaper started to feel bad knowing that Blue wouldn’t be able to experience those romanitc things the couples do. Not even a hug or just holding hands. It was like having a relationship with a hollogram or a deadly creature that could only hurt you. And honestly, it was true.

One day Reaper told him how he felt and Blue, again, said he didn’t mind it. In the end, it was him the one who wanted to touch his lover. He was afraid of losing him for not being able to do simple things like that. Blue was one of the few people who didn’t hate him for what he is.

But even after that, he couldn’t ingnore those thoughts, so Blue decided to give him what he wanted... even if it meant he would die.

They met in a garden filled with lots of hydrangeas (a place Blue loved to visit. Reaper had to be careful to not to kill them) and there, Blue surprised him with holding his hand. Reaper froze and started to panick while Blue was feeling a inmense happiness for finally touch his lover. Feeling his life slipping away, he told Reaper how much he loved him and kissed him before dying in his arms.

### After Blue’s Death

Blue died happy, but Reaper was left alone, feeling terrible for doing this to his love and for just being him. He wanted to go back in time, to prevent this from happening, but sadly, he couldn’t do that. Not alone, at least.

He buried Blueberry in his favorite spot of the garden, took soul and went to ask for help to the only one who could be kind enough to hear him: Toriel.

The goat lady was surprised, to say the least. She and Reaper didn’t have the most happy relationship, and honestly, she thought Reaper would get bored and leave the monster after a while. But he proved she wrong when he begged her to help him... but she couldn’t. Blueberry wasn’t from this universe so she couldn’t help him. Unless...

There was a way to bring him back, but it must require one big sacrifice. In order to bring him back to life, it was needed to use a god’s soul. Reaper didn’t hesitate and offered his soul to her, asking her if she could call his brother and Blue’s brother when she was finnished. She accepted and then the process started. She fused both souls and used Reaper’s body as a vessel for the new soul, making them a baby again with now, a new soul. I wasn’t longer Reaper nor Blueberry. It was now a new life, whose name was Cassis.

### Creation of Cassis

When both Papyruses discovered what happened, they offered to take care of Cassis so they could, at least, have some time with their brothers. Even if they weren’t themselves anymore. From that moment, Cassis was raised in both Underswap and Reapertale. He grew up allready knowing what happened and sometimes acting like both Reaper and Blueberry.

And one day, he managed to go to another multiverse, just for curiosity, and ended meeting that universe’s Blueberry and Reaper, who were both shocked and sad hearing what happened to him. After that, they “adopted” him and offered him a place for when he went to visit them. Little Cass now had lots of homes and a huge family!

So, Cassis is not Blue and Reaper’s child. He is technically them. But he thinks of they as his parents and they love him like he were their son.

## Relationships

### Reaper!Sans (Father?)

Cassis, despite being part of Reaper’s SOUL, refers to Reaper as his own father. Some of his own traits did derive from the reaper himself, which made the two bond more than ever. Reaper had originally planned to just take control of Cassis with his partner, Blue, but the two eventually agreed to let Cassis go and have them live their own life; seeing as the latter deserved it.

### UnderSwap!Sans (Father?)

UnderSwap!Sans also shares the same traits that Cassis has, mainly their energy and love for socializing with others. UnderSwap, like Reaper, we’re originally able to take control of Cassis’s body, but after some time they decided to let go of Cassis; considering that they deserved to live their life how ever they wanted to. Blue loves Cassis like his own son, despite them being a fusion of him and Reaper.
