Character: martlet (zenith form)
Zenith Martlet, as this form is commonly called, is the final boss of Undertale Yellow's No Mercy route. She is a transformation that Martlet undergoes to stop Clover's rampage. The name of this form references the game's description of her as, "the zenith of monsterkind."
She has yellow eyes and a blue beak. Her body is a dark blue like the night sky, her wings have the appearance of cosmic dust and stars, and she has long, flowing blue hair. She wears a dark blue reflective breastplate, as well as the torn, black remains of her pants.
Zenith Martlet is incredibly strong, easily the strongest enemy Clover fights in the No Mercy route. In a sense, she also happens to realize Chujin's dream of monsterkind becoming strong enough to combat humans.
Note: Due to TWYS guidelines, this character should be tagged separately from the untransformed Martlet, unless the two forms happen to be in the same post.
The following are spoilers for Undertale Yellow.
Being a Royal Guard, Martlet is very familiar with the propaganda that human beings are essentially evil creatures. Regardless, she is remains skeptical of the propaganda, firm in the belief that there is good in everyone. This leads her to be overtly kind and diplomatic with Clover in almost every circumstance. However, should Clover be utterly merciless in his approach to monsters, Martlet will be forced to face the reality that the only way to stop Clover is to kill him. From the moment she met him, Martlet had a backup plan in case Clover were to be as evil as the propaganda claimed - a vial of Determination extracted from a human Soul. On a No Mercy run, she injects it into herself, resulting in her transformation into Zenith Martlet.
Clover eventually destroys her breastplate, causing her wings lose both their cosmic luster and their flight abilities. Despite this "weakened" state, she is as strong as ever, and remains determined to end Clover's rampage. As the fight wears on, however, Martlet begins to increasingly suffer from the effects of too much Determination in a monster - her body begins to drip and melt. Upon her defeat, her body completely melts down in horrifying fashion, leaving her screaming in fear and agony before she is scattered into dust.
