Shyren

Shyren is a shy monster with a passion on singing. However, due to being tone deaf, Shyren is insecure about herself and her songs. Shyren is a fish-like monster that resembles a mermaid, ashamed of her scary face and poor singing abilities. Her skin or scales are colored light green and has light blue hair, with one strand of "hair" that has a light green color at the end of it; possibly making her resemble an angler fish. Her "body" is a separate entity from her (which is her agent) while her "head" is her entire body. Shyren is shy, as she tries to avoid encountering Frisk and becomes quiet if they ask her to smile. Due to being tone deaf, Shyren is insecure about herself and her song, but Frisk can hum songs to encourage her to sing. Despite being tone deaf and having no fingers, she is passionate in music, singing, performing, and playing the piano. Prior to Undertale, Shyren once took piano lessons from Undyne.

Shyren seems to speak only in musical notes like "do re mi" or "la la la". Shyren is a monster who is practicing her singing. However, she is very tone deaf that other monsters fear her singing. </Powers and abilities> Shyren was a shy monster who lives with her older sister Shyra in Waterfalls. Shyren was previously friends with Mettaton and Napstablook, and liked the notion of performing with them.

Shyren had originally relied on Shyra speaking in her stead until Shyra have entered a "fallen down" state. Later on, Shyra became a part of Alphys' Determination experiment to see if she can live normally again after getting Determination. However, Shyra ended up merging with other monsters who are test subjects in the experiment, becoming an Amalgamate called Lemon Bread. Shyren shortly after became a recluse because of Shyra's incident.

Later on, when a human named Frisk fell into the Underground, Shyren gets to meet them in Waterfalls. Frisk encouraged Shyren to be more confident in her singing, which ended becoming a concert in the Waterfalls with Frisk and Shyren being bandmates and many monsters who lived in Waterfalls came to see them sing. Which made Shyren more confident in her singing.

Later, when the barrier is broken and the monsters has came to the surface, Shyren reunited with Shyra who is still an Amalgamate, but the sisters are happy to see each other again. At the surface, she becomes a backup singer for Mettaton, joining Napstablook and Burgerpants on tour. She also released her first single called 'When You Say Goodbye It's Like Magical Bullets Are Slowly Flying Out Of Your Mouth And Hitting Me'.
