The Big Four (Azur Lane x Kaiju OC's) [ON HIATUS]
27 parts Ongoing MatureThe Titan Primes were the oldest living organisms on Earth, and older than the Titans by a considerable margin. However the relations between the Titans and Titan Primes were more in favor of the latter, so was their strength and size. After Titanus Gojira Prime, Kong Prime, and Rodan Prime teamed up with one another to take down the mechanized Titan Primes Mecha Gojira Prime and Mecha Ghidorah Prime, then afterwards all 3 went into a long state of dormancy. Then in 2098, portals opened near 4 Titan Primes and sucked them in and transporting them into a different world where they were given the ability to turn into humans and their kaiju forms. The 4 also noticed that this world had enemies that had the same intentions as some in their own world, and they all vowed to protect this world at all costs.
(Note: Yes I know there are similar crossover stories like this one, but since they haven't updated in ages, I've decided to give my own take on this type of fanfiction.)
