Maximus will clear a diagonal line of Tsum Tsum. His base number of Tsum Tsum required to fill the Skill meter is 19. Higher Skill levels will reduce the number required.
Maximus clears a diagonal line of Tsum Tsum 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 Tsum can be cleared.
