Grand Prix

Grand Prix is an offline single-player or co-op mode in which the player attempts to defeat 10 fighters in a row, before (potentially) facing a final boss. It includes a mix of fights and sporting events. Biff commentates in between rounds, providing useful information to the player.

Difficulty levels
The Grand Prix has multiple different difficulty levels the user can select from. The difficulty scale starts at 1 and ends at 7, with difficulty level 1 being the easiest and difficulty level 7 being the hardest, similar to other Nintendo games such as Kid Icarus Uprising. The behaviour of the fighters, and the fights played at the end of the game, change with each difficulty level.

Structure of rounds
The structure of the rounds the player partakes in is as follows *, with small differences depending on the number of players:

Bold text indicates elements exclusive to co-op play.

*No fighter will be fought twice when playing solo. In co-op, fighters may appear twice, but never twice as the main opponent.

**The same mode will not appear twice. For example, if a player plays Skillshot in Match 3, they will not play Skillshot again in Match 6.

All fighters are fought on their respective stage. The only exception is Match 1, however, which takes place at the stage of the fighter selected by the player 1. (Except for Max Brass, who only fights on his own stage during the Grand Finale.)

When you lose a match, you can rematch as much as possible, and save & quit in each round. Except in Springtron's match, it will skip to Grand Finale automatically.

When playing with two players, each round consists of two fighters, not one, with the main opponent shown in the introduction to the match and another selected at random, but not repeating in second role.

Rewards
Upon beating the Grand Prix at any difficulty, the player is granted access to Ranked Matches, allowing them to fight for a certain rank; the mode is otherwise inaccessible. Furthermore, upon beating Grand Prix at difficulty level 4 or higher, the player is shown an exclusive piece of artwork for each character, usually depicting them after obtaining the Championship Belt.

Trivia

 * Because Max Brass' stage of origin is the Sky Arena and can only be played in the Grand Prix towards the end when the player confronts him, whenever playing as Max Brass the first round will always be a fight with Spring Man in Spring Stadium.
 * When playing co-op Grand Prix, the partner to Max Brass at the 10th fight will always be player 1's character.
