Maximus is a Premium Box Tsum. He was introduced to the Japanese version in tandem with the Story Book Lands event (June 2017) and in the International version during the Disney Storybooks event (April 2018).
Maximus will clear a diagonal line of Tsums. His base number required is 19. Higher skill levels will reduce the number required to fill in the skill meter.
Maximus' skill is to clear a diagonal line of tsum tsums with a sword going from the bottom left to the top right diagonally, so turn on gyro mode and tilt your screen so that more tsum tsums could be cleared.
