Super Smash Bros. Clash

[Hoeloe]

"Oh this is a parrel universe that functions like the Nintendo universe you know, but is different because everyone's a toy. NERF!!!"

I'll tell you why this worked.

Smash Bros is a fighting game. Its sole purpose is to have fun smashing the hell out of Nintendo characters with other Nintendo characters. The point is that Smash Bros had other aspects, apart from the story, that made it great. It had gameplay that was fun and new, and generally made for a great time. I challenge you to find me just one person who has EVER bought a Smash Bros game for the storyline.

Now, your work has taken that away. Because you have nothing but the story, your story needs to become much better than that of Smash Bros, because there's nothing else there to redeem it. Smash Bros was made as a fun party game, and had a "story" thrown in just for the sake of it. If you take away the party game aspect, you're left with a story that makes no sense and is totally pointless. This is exactly what you've done. What you need to do to make this work is to strip the concept to its bare bones and start again. Build a new story on the concept that stands alone from anything else.

You've basically done the same thing as taking a house covered in Christmas decorations, then removing the house and expecting the decorations to stay where they are. You need to take down everything and build a new display that looks just as impressive, but built with a different structure and style, which allows it to stand on its own.
