Summary
(A cross-post of an Undertale Crossover on DeviantART of mine that I'm re-working into a fanfic)
While out on a mission in the Ebott Exclusion Zone to deal with a rogue Mechanloid, Axl finds himself curious about a legend surrounding the place and decides to stay behind to explore after convincing Alia that he'll be careful.
Things go wrong and soon Axl finds himself lost in a world of Monsters and with a strange newfound power. With no way to contact HQ or teleport out, Axl must journey through the Underground on foot. Along the way, meeting new friends and foes while also learning that listening to his trigger finger isn't the only option to solve a dispute.
Will he become the savior that Monsterkind and a group of outcasted Reploids speak of in an ancient prophecy or will he perish like the human children that came before him?
