Classic Mode

Classic Mode is a mode in Super Smash Bros. Melee and Super Smash Bros. Brawl that serves as the successor to the 1P Game in Super Smash Bros. The two modes are virtually identical in order; however, certain changes have been made. In the original, the player fought in a predetermined order: the player would always fight a specific character at a certain stage in a fixed order under static conditions). In Melee, randomization elements were introduced - the battles and the order in which they are take place are, for the most part, completely random (other than the basic layout, which is elaborated upon in the below section).  Additionally, the Board the Platforms bonus game has been removed, instead replaced by Snag the Trophies. Interestingly, Classic Mode (in Melee) is actually shorter than the 1P Game in the original. If the player loses all their stock, they are brought to a screen with a "Yes" or "No" answer to the Announcer's question "Continue?" Some coins and points are lost if "Yes" is chosen, but a "GAME OVER" is shown if "No" is chosen or if you do not have a certain amount of coins to pay. At the end, you will lose 20,000 points for using at least one continue, gain 10,000 on easy, 20,000 points on medium, 30,000 points on hard, 40,000 points for very hard, and 50,000 points on intense, and another 15,000 points if you didn't lose a single stock.

Battle types
Classic Mode introduces different types of battles as the player progresses. In Melee, there is one type of each battle in a set stage while in Brawl there are multiple special battles fought randomly in each stage.

Regular battle
In a regular battle, the player engages in a one on one battle with another character. These type of battles are the most common type of battle in Melee and Brawl. The opponent is usually chosen at random and is battled on their home stage.

Team battle
In a team battle, the player pairs up with a computer ally and battles two other computer opponents. The opponents and ally are chosen at random in Melee, while characters of the same series usually team up in Brawl. The battle is usually fought on one of the opposing characters home stage. The higher the difficulty, the less reliable the ally will be.

Giant battle
In a giant battle, the player pairs up with at most two allies and battles a giant character. The giant character will have the same attributes as a character with under the effects of a Super Mushroom, however the enlarged size will last the whole battle. The giant character can usually sustain more damage and has more powerful attacks, but their jump's distance is reduced and they become a bigger target. The higher the difficulty is, the less reliable the computer allies will be. In Brawl, this battle is chosen at random by series and the player will be given a certain number of allies depending on the stage number. When this battle is chosen on stage 2, two allies will fight alongside you. When it is chosen on stages 3, 4, and 5, only one ally will fight alongside you. Finally, when chosen on stages 6-10, no allies will fight alongside you.

Multi-man battle
In a multi-man battle, the player fights ten copies of another character. The opponent team will attack in groups of three, but they have lower handicap than usual, making them easier to defeat and more difficult for them to KO the player.

Metal battle
In a metal battle, the player faces an opposing computer player under the effects that are similar to the Metal Box. A metal character can sustain more damage and are less likely to flinch with more powerful attacks. However, their falling speed is increased and running speed reduced. In Melee, a metal battle is always fought on the Battlefield stage with no items appearing at all. In Brawl, however, the metal battles are chosen at random by series and items are present.

Free-for-All
This battle only appears in Brawl as the second-to-last battle. In this battle, the player must fight three random characters (who haven't been fought yet in the current playthrough) on the Final Destination stage. Often, the opponents will attack each other outright until the one is defeated; the remaining two will then focus solely on the player. The music played in this battle is Opening (Super Smash Bros. Melee).

Final battle
In a final battle, the players faces Master Hand (and possibly Crazy Hand) on the Final Destination stage. When one player reaches the final stage in this mode on normal or higher in under 15 minutes and hard or above in 9 minutes or less in Brawl without continuing Crazy Hand will fight along side Master Hand. However, there are no items present in this battle. Master Hand and Crazy Hand both have certain number of hit points depending on the difficulty you chose that must be depleted to clear this mode. However in Brawl, along with the change of hit points is the movement of the hands. The higher the difficulty, the faster they move. In Melee, Crazy Hand will appear after you cut Master Hand's HP in half. In Brawl, Master Hand and Crazy Hand will both appear at the same time.

Trivia
In Brawl, if the player beats Classic on intense, the narrator will say `PERFECTO!INCREDIBLE!` instead of Congratulations.
 * In Brawl, Halberd will always be fought on in stage 5 due to Kirby characters always being fought in stage 5 and the lack of another Kirby stage that is not a Melee stage.
 * Brawl is the only game in which the character's character is not seen facing their friend on the screen were the narrator announces who is to be fought next.
