When Worlds Collide is the first official Raconian Heroes crossover. It mainly takes place a few weeks after the events of Agnetia the Alien, Episode 6: Darkness Reborn.
Following a mysterious chain of events that brought three heroes together, the universe falls into peril when different timelines and dimensions begin converging. And there's only one man who knows how to fix it.

This is the first story in the main RH canon to unite multiple dimensions, as well as the first ever to show the formation of the Raconian Heroes (hinted in Agnetia the Alien: Star Crossing Lovers).
It has the same Intro page as A Christmas Chaos, the cancelled Agnetia the Alien 2015 Christmas Special.
Agnetia reveals that the planetoid that she and the others are shopping on is named Cribauswaye, which is a reference to Cribbs Causeway, a shopping centre in Bristol, where Agnes Thompson (Agnetia creator and the main writer of this series) grew up.
