Ultraman Era (Ultraman OC X Crossover)

There was once a story of how all worlds become one. Multiverse merger, one of the events showing crisis against Kaiju. And of course, all Ultra's had to interfere to fight them off before the merge was complete. But, when all universes end up merging as one, history has been improvised thus altering the events of their own respective universe. In the new world, everyone becomes one of a community as a government sees potential among the world, thus creating Union Century Hope Academy, in the honor of first Union Academy's downfall from unknown Dark Ultra. While that goes on, only one boy, Kentaro Nogami, now had something special no one expected and never knew his identity... he is the incarnation of the new Ultraman, Ultraman Era. But Ultraman Era isn't the only Ultra around as there 2 of his brothers remain hidden among the people. Now, Shinji must protect his home planet from rogue/evil Kaiju with the power of Ultraman Era as he must end the corruption of Kaiju and end the unknown Dark Ultra with the power of every Ultra Warrior's Spirit in battery component, Ultra-Battery, with transformation device, Era Capsule, to fight against evil Kaiju.
