Magikoopa leader, Kamek, is joining Mario Tennis Aces this month as the latest in a growing roster of DLC characters.
As with all previous characters, you can enter the April Online Tournament in order to unlock Kamek early. These run until April 30th at 5pm P.T.
Also this month, by participating in the tournament, you can earn three different bandanas for Spike.
Kamek first appeared in Super Mario World and is a difficult opponent to go up against, striking curveballs, using topspin and slice.
Dry Bones will be the next DLC character in May.
