Wind Shield

BoBoiBoy Wind has an ability called the Wind Shield (Perisai Angin).

Episode 11
This was only seen when BoBoiBoy Wind started to evolve into BoBoiBoy Cyclone after eating plenty of Yaya's Biscuits. Not even BoBoiBoy Earth and BoBoiBoy Thunderstorm can get through it.

Information
At first, the Wind Shield is white, like the Tornado Shield. But as BoBoiBoy continues to laugh, it turned purple in colour.
