Yes, I know it is a crossover, but: 1) Both events are crossover of worlds. 2) Worlds are going to merge and be destroyed. 3) Heroes from worlds have to fight with each other to protect their own world from that. 4) Kamen Rider (and Super Sentai) is generally considered as Japanese counterpart of DC/Marvel Heroes.
