*MAJOR UNDERTALE SPOILERS*

{Line Quantity Estimate: Medium/High(?)}

The biological child of Toriel and Asgore, and the adoptive brother of the first human. A calm, unadventurous but loving child, he's also said to be a bit of a crybaby. Despite their debatable true nature, he cared and trusted the fallen human like they were a true sibling, going forward with their plan to escape the underground by fusing souls. His death came about when their plan was inacted, allowing them to cross over the barrier with the fallen human's lifeless body. This resulted in the Asriel/human fusion being treated as the murderer of the fallen human, resulting in being lethally wounded and dying upon returning back to the Underground, claiming the lives of both Asriel and the fallen human. Reborn without a soul as Flowey, whom lacked any sort of love and compassion, and revived in this form after absorbing the souls of every resident of the Underground and the six captive human souls.

(Asriel's child form acts nearly identical to Flowey's happy-go-lucky personality, although not nearly as chipper or as falsified, and without any of the condescending sarcasm implied in Flowey's dialogue. Truth be told, he has an innoncent demeanor and a calm tone to his voice, similar to his biological mother. During certain lines, not any of the ones doable for the audition, may sound like he's on the verge of breaking into tears. A few lines might be shared between this form and the form he takes on in the boss battle, so forewarning in advance about that. He also makes a minor apperance in both the Neutral run and Genocide run.)
