Crossover That Time I was Reincarnated Into Worm, Good thing I've read plenty of Fanfiction!

Javier Morales never expected to die the way he did. Guess that's just life for you. Now he's on Earth-Bet, with the Celestial Menagerie, oh and did I mention his knowledge of the universe is based entirely on Fanfiction's he's read. He always did wonder what came after Leviathan. Good luck Javi, you'll need it.
