Summary
Undernova AU: in which the remnants of stars live within monsters.
Over time, due to the frequent experience of negative emotions, the star transforms into a new stage — a "supernova". In this state, the host temporarily shifts into an enhanced, "buffed" version of themselves, which significantly increases the monster's stats.However, it's not all good. When the host's power runs out, they suffer prolonged, severe damage from the star "burning out" inside them, which can potentially be fatal.
Because of the fear of entering the "supernova" phase, some monsters became stingy with their emotions. Others, intoxicated by the unimaginable power, began to sow chaos.Her name was Altair. She was a skeleton monster — the last skeleton left after her father, Gaster, was consumed by the machine. Alta spent years trying to get that junk heap to work, but it remained silent.
Until today.
