Note: Title translates to "Unknown Soldier" in German.
Six minutes before the hijacking of Dimension Tide, the man-eater Gaira attacks an automated boat ferrying nuclear waste near Honolulu, mistaking it for carrying food. The radiation-eating monster HokMuto attacks him for invading his territory and trying to steal his food. Just as Gaira knocks his opponent into the water, the black hole is fired and sucks the man-eater in. The humans surveying the battle are stunned but relieved.
In the present, a Pegasus named Starfall wanders the woods. His job is to collect fallen stardust, a valuable substance with both medicinal and decorative purposes. He muses on how earlier that day, his town found that almost all of its glass, and nothing else, had been stolen. As he chuckles about idiotic and/or crazy thieves, he finds a trail of broken glass. He decides to follow it and find out where the thieves are hiding, then report back to the sheriff. He follows the trail, and at the end he finds a group of wagon-sized demonic beetles. They have gathered a pile of broken glass and glass objects, and several skeletons of both wild animals and a Unicorn. Terrified, Starfall realizes he most contact the army and tries to leave, but one of the beetles spots him and alerts the others. These creatures are the minions of the Kaiju insect queen known as Legion.
The being who borrowed Marigold's raincoat continues to ride the train until he has enough and jumps off. He wanders the tall grass and then levitates across a stream until he sees his reflection. He asks himself who he is, then is plagued by visions of a burning city. He is horrified when his reflection morphs into the three-headed dragon Grand King Ghidorah and taunts him, saying the being bears his blood and thus belongs to him. The dragon tries to take over his mind, but he manages to resist and banish the visions. Then he hears a scream.
Starfall flees from the Legion drones as fast as he can, but the tree canopy is so thick that he can't fly away, and while he has to waste time avoiding bumping into trees, the drones simply slash through them. One of the drones catches up to him and knocks him out. Before they can eat him, the being shows up and kills a few using energy blasts and brute force, causing the rest to retreat. Starfall wakes up just long enough to be horrified by his rescuer's face before passing out again.
The being carries Starfall to the stream and dresses his wounds with strips from the raincoat, commenting that he saved him because he cannot tolerate attacks on people unable to defend themselves. A wagon of ponies approaches, so the being decides to leave him in their care and runs away, but his raincoat comes off and the ponies are shocked by his appearance.
The being eventually runs into his friend Gigan, who identifies him as Monster X. The last thing they remember before waking up in this strange world of talking ponies was being sucked into a black hole. Instead of transforming into native species, they merely shrunk down to three meters tall. Gigan reports that his brother Megalon should be on his way toward them, and he saw a flock of Gyaos. He can also detect Godzilla and Mothra's energy signatures in the distance. Monster X tells of his scuffle with Legion's drones, which should mean Legion herself is here. He says the first order of business is to regroup with their comrades.
