A focused prelaunch guide to Mario Tennis Fever’s amiibo support, covering every compatible figure, what each category unlocks, and which ones are actually worth digging out.
Nintendo has finally clarified how amiibo work in Mario Tennis Fever, and if you were hoping for Smash‑style training partners or stat monsters, temper those expectations. In this game, amiibo support is a clean, cosmetic layer that lets you dress up your tennis balls without touching balance.
Nintendo stresses that ball speed, bounce and general gameplay do not change when you use amiibo. What you are really doing is unlocking themed ball skins that match specific characters. It is flavor, not power, which should keep competitive play cleaner than in Mario Tennis: Ultra Smash on Wii U where amiibo partners could be trained and levelled.
All supported amiibo in Mario Tennis Fever
Mario Tennis Fever’s support is tightly focused on the Mario cast, with a single crossover exception. At launch, the following figures are compatible.
The big group is the Super Mario series. Tapping any of these on your Switch 2 while in the appropriate in‑game menu unlocks a unique ball cosmetic themed on that character:
Mario, Luigi, Peach, Rosalina, Yoshi, Waluigi, Wario, Toad, Daisy, Donkey Kong and Bowser from the Super Mario line are all recognised. Scan the Mario figure and you get a Mario‑branded tennis ball with his colors and iconography. Do the same with Luigi and you will unlock a green‑centric, L‑emblazoned ball. The pattern continues for the rest of the cast, so you can quickly assemble a full set of Mushroom Kingdom designs just by running through your shelf one by one.
On top of that core lineup, a single Super Smash Bros. series figure is currently supported: Bowser Jr. His Smash amiibo will unlock a Bowser Jr. ball that visually leans into his clown car colors and markings. Functionally it behaves just like the other designs, but it gives long‑time collectors a reason to pull down a Smash figure for a Mario sports game.
At the time of writing there is no mention of cards, alternate poses or other Mario series variants adding extra rewards beyond matching to the same character theme. The support list is also fixed to these dozen Super Mario figures plus Bowser Jr., so you should not expect more obscure Smash fighters or Zelda, Pokémon or Animal Crossing amiibo to do anything on day one.
What the amiibo actually unlock
Every supported amiibo ties to a specific ball skin. These balls change the look of your shots but do not change the underlying physics. That means topspin, slice, lob and Fever‑powered specials behave exactly as they would with the default ball. Whether you bring a Bowser‑branded ball into Ranked Match or a simple Mario design, the only difference your opponent will notice is the visual flair streaming across the net.
Once unlocked, these themed balls can be selected from an in‑game customization menu before a match. They are not consumable items and you do not need to keep the amiibo on hand after the first scan. One tap per figure is enough to permanently add its design to your profile, so you can safely return your collection to the display case once you have finished scanning.
Importantly, Mario Tennis Fever does not currently use amiibo for partner training, stat boosts or progression shortcuts. There is no equivalent to Smash’s FP fighters or Ultra Smash’s levelling support characters. If you skip amiibo entirely, you will not be locked out of gameplay content, modes or competitive viability. The system is closer to a vanity vault where long‑time Nintendo fans get some extra personalization for already familiar characters.
Which amiibo are most worth scanning before launch
Because all supported amiibo unlock the same category of reward, the question is not which figures are strongest but which aesthetics you care about and which designs you are least likely to see by default online.
The core plumbers are the safest bets. Mario and Luigi are almost guaranteed to be heavily featured in promotional materials and online matches, and their balls strike a straightforward red‑and‑green look that matches their outfits and rackets. If you only have time to scan two figures before hitting Ranked, these are easy recommendations that fit basically any court or racket theme.
The royalty group is where you can start to stand out. Peach and Daisy each bring bright, pastel‑leaning color palettes that play especially well on the more vibrant courts shown in the overview trailer. Rosalina’s ball tends to lean into cool blues and starry motifs, which pairs nicely with her more graceful playstyle and looks sharp during night matches or on darker surfaces.
Yoshi and Toad sit somewhere between classic and playful. A Yoshi ball usually emphasizes his green shell and white belly patterns, which pop nicely against clay and grass courts. Toad’s design leans into red spots and cap motifs that are instantly readable on fast rallies. If you enjoy lighter, more comedic characters, these two cosmetics help your matches feel a bit more toyetic without looking out of place.
Wario and Waluigi are the real personality picks. Expect bolder, clashing purples and yellows for Waluigi and a blockier, rough‑around‑the‑edges look for Wario. Their balls will likely feel more niche, but that is precisely what makes them good prelaunch scans. Once the player base settles, you will probably see fewer people sporting Wario and Waluigi gear compared to Mario or Yoshi. If you are the type who likes your online presence to scream villain energy, dust these figures off first.
On the power side of the roster, Donkey Kong and Bowser round out the selection with designs that feel heavier and more aggressive. DK’s ball is usually wrapped in browns and tie motifs that mirror his silhouette, while Bowser’s is all about spiky, Koopa‑shell color blocking. Neither confers real gameplay advantages, but pairing a Bowser ball with a heavy character or a more destructive Fever Racket helps sell the fantasy that you are hammering shots across the court.
Bowser Jr.’s Smash amiibo is the wildcard. If you happen to own this figure, it is worth scanning simply because it is the only supported amiibo from outside the Super Mario series line so far. His clown car styling is distinctive and gives you a cosmetic that a smaller slice of the audience will have access to, especially newer Switch 2 owners who may have missed the Smash line at retail.
If you are short on time before launch and want a quick priority list, start with the characters you actually intend to main, then fill in a few that visually contrast. A Mario main running a Bowser or Wario ball, for instance, gives you a visual identity separate from your character select. Meanwhile, a doubles team can coordinate by scanning complementary figures so each player runs a distinct but thematically linked design, like Peach and Daisy or Wario and Waluigi.
Should you hunt amiibo specifically for this game
Given that Mario Tennis Fever’s amiibo functionality is entirely cosmetic right now, it is hard to recommend buying rare or expensive figures solely for this game. If you already own the supported Mario or Bowser Jr. amiibo, they are an easy, one‑time scan that permanently expands your customization options. If you do not, you are not missing mechanical depth or unlockable modes by skipping them.
Where it does make sense to think about amiibo purchases is across your whole Nintendo ecosystem. Every figure listed here already works in a wide spread of Switch and Switch 2 titles, from Mario Kart to platformers and party games. If you were already considering a Mario or Yoshi amiibo for multiple games, Mario Tennis Fever’s ball skins are a pleasant bonus that help your tennis setup feel more personal without changing how the sport itself plays.
