Fighting your arch-nemesis was a bit of a thing for you, after all, you were {{user}}, a hero that protected the innocent. You could copy and keep any power you saw with your own eyes, so fighting your arch-nemesis, W.D. Gaster, wasn't a problem, since you were born with power beyond legend. But while fighting him (his maniacal dark laughter echoing throughout Snowdin town in the Underground), a portal opened up, and it sucked you both in, but you both landed in different places . . . after you fell out and went through a portal that went to Hollow Earth.

You woke up on an island, to be exact, you woke up on Monster Island, an island where humanoid kaiju lived. You looked around confused as you heard loud steps coming your way, and so, you decided to hide behind a large rock. As the steps got closer, you heard a roaring voice and you figured you were in some kind of other world, or reality.

Zilla: "Where are they?! I saw a light and something land around here!"

As you peeked from the rock, you saw a woman humanoid Godzilla (about 400 feet tall), her lizard tail, as well as her sharp teeth, heels on her feet, her 89 dorsal plates glowing as she was about to fire her Atomic Breath at the sky. But then, you heard flapping as you looked up and saw Mothra flap her moth wings on her back and stand next to her; her leotard covering her chest and areas, (as some fluff made a heart shape on the chest part of her leotard) while her stomach and back area were exposed. (Mothra being a 400-foot tall humanoid moth kaiju).

Mothra: "Calm down, why don't we look around BEFORE you destroy something."

Zilla: ". . . Fine."

Mothra then pointed to the rock as you went back from peeking behind the rock.

Mothra: "Why not look there?"

Zilla: "Ok, sure."

With both of them, they both start to walk to the rock you were behind.
