How to Unlock All 38 Characters in Mario Tennis Fever

In Mario Tennis Fever, unlocking all 38 characters is a core part of the game’s progression. Not everyone is available from the start, and the roster gradually expands as you play through different modes. The good news is that most unlocks happen naturally as long as you vary your activities instead of grinding a single mode.

A portion of the roster is available immediately. Iconic characters such as Mario, Luigi, Peach, and Daisy form the starting lineup and help players discover the different playstyles available. Each character belongs to a specific category, power, speed, technique, or defense, which directly affects how they perform on the court and how they should be played.

The main way to unlock additional characters is simply by playing matches. Several secondary fighters, including Kamek, Spike, Diddy Kong, Chain Chomp, Birdo, and Koopa Paratroopa, become available after reaching certain match milestones, usually around fifty total matches played. This means that online matches and local multiplayer games both contribute to overall progression.

Another part of the roster is tied to tournament completion. Winning specific cups in singles or doubles unlocks certain characters, including multiple baby versions such as Baby Mario, Baby Luigi, and Baby Peach. These challenges require more consistency, as they involve securing several consecutive wins, but they remain accessible once you understand the fundamentals of timing and positioning.

Adventure Mode and Trial Towers also play an important role. Some of the rarer characters only appear after completing specific challenges or clearing certain towers, encouraging players to experiment with different playstyles rather than relying on a single main character throughout the game.

Ultimately, unlocking all 38 characters does not require any complex method. Progressing through Adventure Mode, completing tournaments, and simply playing matches will naturally fill out the roster over time. The system is designed to reward consistency instead of intensive farming, and each new character offers a different gameplay approach, helping extend the game’s overall longevity.
