Find your tribe in a Sea of Creativity
It should be noted that Rev absolutely hates Kaizo with a rage that only exist once you witnessed your family getting hurt. (I'm watching you, Season 3 of the original BoBoiBoy series)
BoBoiBoy acts cold towards Kaizo and doesn't want him to be anywhere near his brother.
So expect these two brothers to not acknowledge Kaizo in the same room.
And that's just the least 'nice' thing they could do, before comitting worst possible actions to him.
