Does the concept of multiverse exist? Is there any world existing from our own out there? They need no justified answer for that, but for whatever happening, they swear to protect it from the chaos. BoBoiBoy X Mechamato crossover fanfiction I swear, no time travel stuffs here :"D

Okay, I know you'll think this is a series like the others when Boboiboy is transported to the world of the Mha universe right? But this will be different, what if instead of our young hero, an element of him was transported to another world by accident? And the element I chose is Boboiboy Ice. Why? Because he's one of my favorite elemental. Actually, I still haven't watched Mha until now but that doesn't mean I won't learn about it Warning: there's going to be a bit of OOC, I'm not sure yet but I'll say for sure :). ( English is not my native language so please understand)

Before joining TAPOPS, BoBoiBoy is actually one of the MATA's young agents and the most talented agent in MATA because he can mastered all cores.In MATA,he was known as Agent Elemental and no one knows his real identity. But when he got an invitation to train the new batch of young agents,he came back. Ali was always bullied and shunned away by the young agents except Alicia.When he knew the legendary young agent coming back to Academy,he become excited but of course,there would be problem happens everywhere!Hehehe...

Lance Corporal Fang wants to make his brother proud by rising through the ranks in TAPOPs. With this, he (begrudgingly) enlisted help from the infamous young captain, asking for him to be his "mentor". It's not going to be an easy ride with a stubborn person like Captain Solar. But they'll work it out. Hopefully.

Boboiboy and his friends joined an important mission to protect a power sphere, but it seemed it was not going to be an easy mission. "I'm sorry, I never thought he will betray us. It's my fault to let my guard down" A new adventure in another world.How will Boboiboy get used in a weird world? What people's reaction to the Boboiboy? ------- My first fanfiction story. Both characters from Boboiboy and One Piece not mine. Some storyline from the original story, but other than that is mine.

He failed as the eldest brother. He had lost his mind. He is a goner. He thought he totally deserved it. He feared losing any more love ones. He is slowly losing hope. He kept hurting his close ones unintentionally. Everything had drastically changed for the elemental septuplets and their friends after a tragic event happened. Everything was never the same again as it used to be. Can things go back to normal? Who knows. ~~~ WARNING: SLIGHT GORES AHEAD PLEASE DO NOT PROCEED IF YOU'RE NOT COMFORTABLE WITH GORES. Thank you.
