Shyren, after humming once

Shyren (JP: シャイレーン) (/ˈʃaɪrən/) is the sixth miniboss in Undertale. The protagonist can encounter Shyren nearby Waterfall's piano puzzle.

Profile

Appearance

Shyren is a fish-like monster, 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. She fights with her back turned to the protagonist. Her "body" is a separate entity from her (which is her agent) while her "head" is her entire body. This can be seen in battle after either sparing or killing Shyren.

Personality

Shyren is shy, as she tries to avoid encountering the protagonist and becomes quiet if they ask her to smile. Due to being tone deaf, Shyren is insecure about herself and her song, but the protagonist 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.

Both of Shyren's True Pacifist ending credits epilogue texts allude to her constant interest in performing: Shyren's default white text is "Taking Piano Lessons Again", as Undyne used to teach her. Shyren's yellow text, "Released Her First Single 'When You Say Goodbye It's Like Magical Bullets Are Slowly Flying Out Of Your Mouth And Hitting Me'" is a joke on Shyren's attacks.

Etymology

Shyren's name is a portmanteau of shy and siren.

Main story

Shyren had originally relied on her sister speaking in her stead until her sister went missing. She shortly after became a recluse. Shyren was previously friends with Mettaton and Napstablook, and liked the notion of performing with them.

Neutral Route

If Shyren was the only monster killed, Undyne acknowledges this atop the crag in Waterfall.

True Pacifist Route

In the True Pacifist Route Epilogue, Shyren is reunited with her missing sister, who has transformed into an Amalgamate. During the ending credits sequence, she becomes a backup singer for Mettaton, joining Napstablook and Burgerpants on tour.

In battle

Attacks

• Shyren attacks with music notes from her head. These get faster and more ample every time she is hummed to.

Strategy

• To spare Shyren, she must be Hummed to at least once.
• If the protagonist selects Hum five times, Shyren is instantly spared. This also unlocks her yellow text in the True Pacifist ending credits.

Trivia

• Naming the fallen human "Shyren" during the name selection prompts the response "...?"
• On the official Undertale Tumblr, Sans suggests doing research about Shyren's lower body, then immediately disregards the notion.
• Shyren sometimes utters the phrase "Si-Re Si-Re, Si-Mi Si-Mi" during battle, which may be a reference to "Si-Re Si-Mi" by Franco Godi.
• The words that Shyren says seem to be the solfège scale from re to si. Although sol is usually spelled with an "l", Shyren uses the variant two-letter spelling; this may be to keep the two-letter sequence going.
• If Shyren is hummed to 5 times, Knight Knight can be put to sleep one turn earlier than normal.
• Shyren's song is mentioned in a unique encounter with Woshua and Aaron at the SAVE Point near Blook Acres.
• Shyren is one of the monster species making up the Amalgamate Lemon Bread; specifically, Lemon Bread is spared by humming, an ACT adopted specifically from Shyren, and Lemon Bread appears to have Shyren's agent as her main body, giving her a similar overall figure to Shyren's.
