Hiro Hamada was a smart boy who wanted to test something out during a snowstorm

"  alright, I think it's ready, I just need make sure nothing goes wrong" Hiro says with a smile

" Bro are you sure it's a good idea, I don't think it's good idea at all" Tadashi says

" come on bro I've been working on this for weeks. Just let me try it" Hiro says

" alright, fine, I'll stay here " Tadashi says

Hiro gets the gun ready aiming for the iceberg

" ready Aim fire " Hiro says shooting a gun with chemical Z

" look Bro there are 3 white Z-Rays and  black Z-Rays as well" Tadashi says

" oh, shoot, I didn't know that would happen" Hiro says

What the boys don't know was that they were about to make heroes thx to Hiro's experiment
