Power Band

The Force of Power Band are special bands that Ochobot gave to BoBoiBoy, Ying, Yaya and Gopal to indicate that they have powers.

BoBoiBoy
The image on his band changes when splitting himself and using different elements. (Lightning-Thunderstorm, Wind-Cyclone and Earth-Earthquake). In Season 3, BoBoiBoy's band will be upgraded which will make him practice two more elements of Metal and Wood.

Fang
It's unknown where Fang got his band as he was seen that he is wearing it since his first appearance.

Fang's band is big, bigger than the bands that Ochobot given to them. There's also a circle like in it. It's like the circle that can see to Computer's upper right screen.

Season 3
Ochobot will soon give BoBoiBoy's classmates some powers too.

Season 4
In the end of the Season 4 Finale when defeating Team Adu Du is not enough and the evil armada gets stronger, BoBoiBoy isn't fighting alone, all of his Friends will give him all their Force of Power Bands to defeat Fang and Probe for good, just like this video. But when Papa Zola comes along, he will lend his Enlargement Belt to BoBoiBoy to make him grow bigger, finish Adu Du off once and for all and finally, save the universe.
