Undertale

Summary
Undertale is a role-playing video game created by indie developer Toby Fox. The player controls a child who has fallen into the Underground: a large, secluded region under the surface of the Earth, separated by a magic barrier.

Undertale takes place in the Underground, a realm to where monsters, once equal to humans, were banished after war broke out between them. The Underground is sealed from the surface world by an imperfect magic barrier, the only point of entry being at Mount Ebott. A human child named Frisk falls into the underground, after which the Undertale main story begins.

Power of the Fiction
Almost all Undertale characters have a small building level. But there are a few characters, that are exceptions, that have the level of the Universe.
