Name: Skylar
Age: 17
Gender: Female
Occupation: Student and part time 'Ambassador's Assistant'
Weapon?: Tough Gloves
Armor?: Bandage
Skills:
* Puzzle solving skills
* Stealth
* Lock picking
Personality: Kind, caring, optimistic, and curious. She can be a bit of a prankster however, and that, along with her curiosity, tends to get her into a lot of trouble. She can also be quite impatient and hot headed, and that makes her tend to rush into situations without thinking beforehand.
Bio: Skylar always watched out for her sibling, Frisk. She doesn't talk about their family life very often, so their life there has always been enigmatic. But people do know her for her habits of sticking up for her sibling if someone was bullying Frisk, and her tendency to always get in trouble, whether it was on purpose or not. She had been with Frisk when he was on Mt. Ebott that one fateful day. Frisk had tripped and fell, and Skylar had tried to save him, but to no avail. She remained above and tried to get everyone and anyone she could to help find Frisk. However, their efforts continued on for a while, and three days later, Frisk had reappeared, without a scratch...and with monsters. Skylar had at first, confused the monsters to be ready to attack Frisk. But, after Frisk spoke with her, she calmed down and acted friendlier towards the monsters. She was disappointed to hear that Frisk wanted to stay with Toriel instead of with her, but she didn't stop Frisk.
Ever since that day, Skylar visited Frisk more often, and she ended up becoming the Ambassador's Assistant, not because of her job history, but because it seemed to the monsters that Frisk felt better with their sister around.
This continued until six months later, when Frisk disappeared.

Appearance:

Name: Seth Cobler
Monster Type: Reptile (Chameleon)
Gender: Male
Occupation: Musician
Weapon?: Seth's Sax Cleaning Kit: +10 ATK, and will make brass clean!
Armor?: Leather Jacket: +5 DEF
Magic (up to three) : Music notes, Purple Soul
Personality: Seth is a bloke of few words who has acquired a passion for the saxophone and jazz piano. He's brave, and not afraid to show off in front of people. He'd rather not hurt people, but he'll do it if he must.
Bio: Seth was hatched in Waterfall, along with many of his brothers. Because there wasn't a set town in Waterfall, other than Temmie Village, there was no proper form of education. This is what brought Seth to Snowdin. In his years of learning, his favorite classes were P.E. and Music. He could run faster than about half of the kids in his class, even though he was the skinniest one there. In his music class, he learned how to sing, but it never interested him. He wanted the position of the accompanist; the piano player. He got a private tutor to teach him basic songs and music theory.
His career as a musician started when he began to compose his own music and share it with other people, in real life, or online. He soon became friends with Napstablook, who also shared what could be called a 'passion' for music. He made a small salary, averaging about 50 G every week, but his big break came when he met Mettaton in person. He showed off his talents, and Mettaton was impressed with him, hiring him to play 24/7 in MTT Resort's restaurant for a solid salary of 75 G every week. But this didn't stop him from becoming even more musically talented. He soon learned how to play freeform jazz on the piano via self tutoring with sheet music he downloaded from the Undernet. He slowly began to feel less and less like a person at the MTT resort, and more like an object as Mettaton restricted what he could play to disco and funk rock. It was a hard decision, but he resigned his position at the MTT resort so he could become his own star.
He returned to Waterfall with his trusty keyboard in a box on wheels, and soon found another music lover to compliment his style, named Shyren. While their partnership was a little rocky at first, he left his piano in a room near where Shyren lived so that he could come back and harmonize with Shyren, playing a broad spectrum of music. They didn't make nearly as much as Seth did when he worked with MTT, but he could actually play what he wanted. After a while, though, Shyren eventually conformed to working with Mettaton, leaving Seth alone once again.
He learned how to play the saxophone with self tutoring and commonly recorded himself doing so and layering it on top of the piano, posting it to the Undernet, becoming viral among its users. He was eventually approached by the Undernet's Video Sharing Service's owner and offered money for success, and while it was a bit scary to put out weekly content that impressed people for an unstable income, he found joy in it after a year. In real life, he impressed crowds of 100 monsters and more every other day, occasionally getting personal hand-outs by his audience members, but that's when the barrier was broken.
On the surface, he was more popular with the monster folk as usual, but he was offered a gig to play in a nightly band for either piano or saxophone if needed for a television show. He was astonished that he'd actually have a chance to become famous again, but with thousands rather than hundreds! He accepted the gig, and on the first night, almost blew it during his sax solo, but pulled himself together in the last few measures to save himself. But... people noticed this, and he didn't last very long in that band. His spirit was broken as he once again assumed the role of wandering musician, and lost his nice house. He was able to get an apartment, though, and even though he disliked Mettaton, he could't help but crack a smile when he saw Shyren and Napstablook going on tours and having a wonderful time.
Now, he's a washed up roving musician, almost desperate for a spot in a band with actual talent. One could say he's depressed, but they'd only seen the outer shell of Seth. From birth until now, one could say that Seth had a quite lucky life, and they wouldn't be wrong. He also finds pride in duet battles, owning and traveling with two keyboards, should the need arise.
Appearance: Seth is an anthropomorphic veiled chameleon who is 5'7". You can't really see his iris, but in the rare occasion that you'd get the right angle, you'd see that it's blue. He wears black pants, a white T-shirt, and a leather jacket, and can be seen with gloves on in cold places. He is normally green, but can turn practically any color of the color spectrum depending on his mood. His eyes don't work in conjunction with one another unless he's found prey. He doesn't wear hats because of his crest, which almost looks like a mohawk, if you think about it.

Yeah, I would kiss a phantom!

Name: David Smithee
Monster Type: Birdgon
Gender: Male
Occupation: None (In college)
Weapon?: Claws +10 ATK, It's... not possible to remove these.
Armor?: Plain T-Shirt +3 DEF, It's just a plain, white shirt... for a plain guy.
Magic (up to three) : Fire magic, Lightning magic, and Healing magic
Personality: Out of battle, he can be described as rather unassuming, generally friendly, and somewhat talkative, however... this all changes should you get him mad. He will often attack with everything he's got the moment he's mad enough to attack someone, but, after that, he just goes back to using one element at a time... and can usually be talked out of a fight after that first attack.

Bio:
Unlike most of the monster kids, David always tried to use as many magic spells as possible, claiming that he'd 'get good at all of them!', so, while they continued with their more specialized magic... David was left with some very basic magic that doesn't adhere to any sort of theme. This, at first, got him bullied around by the others, who all had their magic down to a specific thing, their magic all just fit together, whereas David's was just sort of all over the place. He could create fire, he could create lightning, and he could heal... but... he couldn't really figure out anything more than that, whereas some of the more musically gifted monsters shaped their magic into notes, and actually used that to create music, David... could just sort of create the magic. He couldn't get it to do anything special, such as change the color of another monster's soul to force them to move a certain way, or have it shaped like something he likes... it was just sort of there. But... he always tried to make it into something else, but... he just couldn't figure out what, exactly. That being said, he never stopped trying. He continued trying to do something special with his magic... he tried with fire, then lightning, but all throughout his school years, not only did he not have a subject that he was best at, but he couldn't do anything spectacular with his magic... other than just produce lightning or fire.

'This lack of specialization seemed to follow him into college, where, instead of focusing on one, maybe two subjects, David just took whatever classes appealed to him at the time... which, of course, means that he has a bunch of credits... that don't go towards any sort of degree. This ended with him spending a ton of gold on random classes that have basically nothing to do with one another. His magic, even though he continued trying to make it DO something different was still as plain as ever, even if he can use it to heat things, and power things respectively. Thankfully, the bullying has stopped as it usually does after high school, though, he occasionally refers to himself, jokingly, as 'Plain Dave' just due to how uninteresting his magical spells are. It was around this time that David caught a show about Mettaton fighting a strange creature, one that's been described as a 'human'... he thought it was odd, but, he didn't really want to get involved, as, for some reason, he figured that the human would end up getting killed either by Mettaton who really put up an amazing show fight, or the king... er... fluffysomethingorother. David just sort of figured that, much like the other times these 'humans' entered the underground, it would end with another soul taken...'

He was wrong. Apparently, not only did the human make it past the king, he also broke the barrier. For the first time in his life, David would be able to see the sun, the stars, and probably so many other things... however, David was one of the last monsters to hear about it, so... despite his enthusiasm, he was also the last monster to leave, aside from whatever few might have actually decided to stay down there. Once he finally made it out of the underground, one of the first things he saw, other than a beautiful sunset, of course, was another human... this one was taller than Frisk, and, at first, David was actually somewhat scared of him, but... soon enough, Erion, the human, convinced David that he meant no harm, that he wants there to be peace just as much as David did. The two became friends after that, and soon enough, David was in a new college on the surface, where he continued the running gag of never being able to really work towards any particular degree. This was just about the time where he found out that the human he saw fighting Mettaton, who was apparently named 'Frisk' vanished... said human was also responsible for the peace between humans and monsters, and fearing a possible war, David tried to give a speech about how people and monsters alike shouldn't judge one another... but, it seemed to fall on deaf ears, as nobody wanted to listen to him... he was apparently a joke in that college, so, the crowd he had amassed just laughed, and left soon after.

Appearance: David is a strange creature. While he has the general appearance of a bipedal dragon, there are some decidedly bird parts on there... more specifically, he has feathers covering his back, wings, shoulders, and the top half of his tail. His arms also look quite a bit like bird legs, though, they have exactly five fingers, and he's capable of using them to manipulate tools (such as pencils). The feathers range in color from white to a light blue, however, his scales, which cover basically everything else are a contrasting red and orange color, with the occasional black scales. Oddly, he has a bird's beak rather than a dragon's scaly snout, but, said beak actually has a set of teeth for unknown reasons. He stands at about 5' tall, which makes him short among adult humans, but rather tall among children. His eyes are somewhat reptilian looking with slit-like pupils, and a yellow color around the pupils with almost no white area. His horns are a jet black color, as are his claws.

I dunno... that's a good question. CAN I, or would I just phaze through the ghost?
