Mr. Resetti

Mr. Resetti (, Reset-san) is a character from the series.

Origin
In the first four Animal Crossing games, Mr. Resetti appears whenever the player walks out their house after resetting the system or turning the power off without saving. Mr. Resetti then proceeds to bother the player by giving a long lecture on how "resetting" the game is bad. The player usually has to apologize to Mr. Resetti in order for him to leave. Sometimes though, apologizing isn't enough for Mr. Resetti: he keeps shouting, and sometimes make the player repeat a phrase that is meant to humiliate them (such as "I'm dirt"). He also sometimes gives a code that he says and the player must type it correctly.

Mr. Resetti's role in the Animal Crossing franchise has diminished in recent years due to real-world incidents of him making young players cry - the aggressiveness and length of his lectures were toned down in New Leaf; while in New Horizons he is implied to run in-game alongside his brother Don Resetti due to the autosave feature rendering their original jobs obsolete. He was formally added in New Horizons version 2.0 and can be invited to the or to the  for a vacation home by. The dialog that he gives to the player in The Roost implies that he has become calmer and more tolerant to players resetting since he was removed from his roles in the previous games. He also makes a small cameo should one's internet connection fail while playing online, alluding to the fact that the game is forced to reset to the last save as to not cause save corruption.

In Super Smash Bros. Melee
Mr. Resetti only appears as a trophy.

Trophy
Because Melee was released before Animal Crossing internationally, Mr. Resetti's first appearance is listed on his trophy as "Future Release".

As an Assist Trophy
Mr. Resetti makes an appearance in Super Smash Bros. Brawl as an Assist Trophy, where he simply sits where he was released and lectures the players with long monologues that can last for over a minute before leaving with his signature "SCRAM!". His large text boxes obscure a large section of the upper playing field, which can be distracting to fighters, or the lower area of the screen (depending on his position), obscuring the damage percentages. He will respond to certain events, such as him falling off the playing field on a moving stage, where he will say, "H-hey! Don't you ditch me punk!". It's possible to interact with him by attacking him, but doing so only adds to his complaining. If a player attacks Mr. Resetti enough, he will respond with an explosion, while asking the attacker to "QUIET DOWN, WILL YA!". This explosion can harm players. He will also block projectiles that are thrown at him.

Depending on the time of day, Mr. Resetti may make a comment (for example, at night, Mr. Resetti tells players to "Get some shut-eye", adding that "Staying up late is for punks"). He will also do impressions of characters on the field (calling them by their player name if those are being used, and usually their win screen taunt). Mr. Resetti's text box will be visible regardless of the camera position, and even show up on Snapshots.

One-player glitch
By entering a match with only one player by means of hacking and getting Resetti out of an Assist Trophy, Mr. Resetti is forced to say his own name instead of the nonexistent second player's name, in the sentence "[Player 1].... [Player 2].... You'd be runnin' home to Mama!". The glitched message will appear as "[Player 1].... Resetti.... You'd be runnin' home to Mama!". Presumably, the game is programmed to display "Resetti" if there is any sort of error getting the intended target's name, using his as placeholder.

As a background character
While Mr. Resetti is not an Assist Trophy anymore, he makes a background appearance in the Town and City stage.

In Smash Tour
Mr. Resetti appears as a red trophy item: when used he resets chosen opponent's stats to zero for the upcoming battle only.

As a background character
Mr. Resetti reprises his role as a background character in Town and City.

Spirit
