How Many Characters Can You Unlock?
Mario Tennis Fever launches you onto the court with 18 characters ready to play. The remaining 20 fighters require specific actions to add to your roster. Some pop up after just a handful of matches while others demand tournament victories or challenge completions.

What Are Color Variants and How Do You Get Them?

Best Rackets for Competitive Play
Not all Fever Rackets perform equally in high-level matches. Here are standout options worth prioritizing:
The Ghost Racket turns both you and your shots invisible, creating nightmare scenarios for opponents trying to read your plays. The Golden Dash Racket dramatically extends your diving range, letting you save shots that would normally be winners. For pure disruption, the Inky Racket splashes ink across your opponent's screen exactly like Blooper items in Mario Kart.

What's the Fastest Way to Unlock Everything?
Efficiency matters when you're chasing 100% completion. Here's how to maximize your unlock rate:
Start by grinding matches in any mode that counts toward your total. Quick Play and Exhibition matches both contribute to your counter. Aim for reaching 50 matches first to grab all the easy character unlocks.
Once you hit 50 matches, shift focus to tournaments. Work through Mushroom, Flower, and Star Cups in both Singles and Doubles to claim the Baby roster and Nabbit.
Finally, tackle Trial Towers and Score Challenges. Save these for last since they require genuine skill development rather than simple repetition.
