Well there should be a part where he's playing soccer (since he's Brazilian). Then a player on the opposite team pushes him to the ground for the ball. Then Roberto gets mad and wants revenge so he tackles him. Then they fight and players on both teams help. Then Roberto doesnt know but he's suddenly asborbing enegry from the sun. Then he looks like when his powers are activated.
Oh yeah thats what happened in the comic ๐ฑ
