Reminder: I do not own Adventure Time or Pacific Rim or Exonaut Robots besides fan made ones.
Kaiju: Gigantic Beast
Exonaut: External Warrior
Finn: Three years after the war between the Xenomorphs and the Cyber-Yautja and then became a happy ending with OOO's regeneration thanks to PB. When I looked at the stars, I was worried that there are more threats like before coming. But I looked the wrong way. A giant mysterious glow appear underwater of the Pacific ocean. It turn out to be a giant portal called the Breach. When me and Flame Princess are married, a giant monster known as Kaiju terrorized OOO.
An axe headed monster that is about 300 ft. tall is seen destroying the candy kingdom, crushing buildings and houses, battling gumball guardians, and killing some candy people.
Finn: The first one made land at the candy kingdom. Luckily my wife use the fire kingdom's big volcano cannon to kill it. And it worked.
The giant creature's burn corpse is seen after being shot by the fire cannon. Few days it became a display at the turtle kingdom museum.
Finn:We were relief that it was over until we realized that it was the beginning of the Kaiju Invasion.
Another monster that is black and with yellow lines and have a horn on its head was seen attacks the goblin kingdom.
Finn:The second attack the goblin kingdom. Then the third hit Marauder Village. The fourth in lumpy space. The fifth in fire kingdom that destroyed the volcano cannon. More and more keep coming until we learn that this is never gonna stop.
Many Kaiju are seen attacking most kingdoms, villages, and valleys.
Finn: We did summon many allies including the Yautja but to weak since they battled some powerful Kaiju. At the grand OOO meeting we discussing about how we win this new war. Then we got the key to victory and hope, MOE. In order to fight monsters, we created monsters of our own.
Many workers, engineers, and working robots are seen creating giant mechanical robots.
Finn: The Exonaut was born. As we tested to control the Exonaut it causes some serious problems to a single pilot. So we used two or more pilots instead and it successfully worked out. We started winning multiple battles and even losing a few Exonaut to the stronger Kaiju. As the war between Exonaut and Kaiju passing time it became popular like their was toys, games, shows, costumes, movies, documentaries, books, comics, parody foods, and many merchandise about them. When we were winning, it all changed.
