Bowser Jr. just like his dad finds himself on the field as a captain for the first time in Mario Strikers Charged. Jr. is a Offensive type player who excels at passing and shooting the ball. When you charge up his Mega Strike he kicks the ball in the air before jumping behind it, as his head grows the background turns green before he releases it in a sonar wave to make the ball go flying at the goal.
His Super Ability Sonic Roar! like his Mega Strike produces a sonic wave but this wave makes any player hit by it shrink. When shrunk the player is much slower then full sized characters and are much weaker when shooting. If this is used on a Captain who is using a Super Ability that lasts over time, it will cancel it out.
Bowser Jr. is unlocked by beating the Fire Cup which you must play him in the finals for a best of three matches. When he uses his deke he jumps in the air and does a ground pound with his shell stunning those who are close to him. He wears a orange unifrom and his emblem is a spiked wristband simlar to his father's.
