Completion

Every game in the PS undefined can be completed in varying degrees. Some players may consider their play time with the game completed after just beating Story Mode, while others may want to finish everything the game has to offer. The following is a list of completion goals that exist in every game. Some of these objectives are acknowledged by the game, and unlock new content or mark something in the player's stats, while others consist of subjective goals that, in general, most players would consider part of "100%" completion of a game.

Pikmin
has 3 endings: the bad ending, reached by playing all 30 days without getting enough ship parts, the good ending, reached by getting at least the 25 mandatory ship parts by the end of the 30 days, and the best ending, reached by getting all 30 ship parts.
 * Reach an ending

Getting all 30 ship parts is the main way that Pikmin Story Mode can be completed.
 * Collect all ship parts

Since each stage has a maximum number of Pikmin that can possibly be grown, it is possible to complete Challenge Mode by getting the maximum score on each stage. However, no human has ever done this, as getting a perfect score of 752 in The Distant Spring is incredibly difficult, and has only ever been done in tool-assisted superplays.
 * Complete all Challenge Mode stages

Pikmin 2
first ending occurs when 10000 Pokos have been obtained, which causes the credits to play.
 * Repay the debt

Pikmin 2 second ending occurs when all 201 treasures have been collected. This completes the Treasure Hoard.
 * Collect all treasures

By interacting with or defeating all the creatures, it is possible to unlock all 81 entries in the Piklopedia.
 * Completing the Piklopedia

On top of clearing all 30 Challenge Mode stages, the player can also beat each one with a pink flower (which is done by completing the stage with no Pikmin deaths), thus effectively completing Challenge Mode. Doing this unlocks a secret cutscene.
 * Complete all Challenge Mode stages

Pikmin 3
ending occurs when the Plasm Wraith is defeated in the Formidable Oak. There are 4 variants of the ending, and which is seen depends on how many fruits are collected.
 * Defeat the final boss

The best ending occurs when all 66 fruits are collected. This is the standard way of completing Pikmin 3 Story Mode.
 * Collect all fruits

In addition to collecting all fruits, Story Mode can be fully completed by collecting all data files and gear.
 * Story Mode 100%

In exclusively, there are 50 badges that can be unlocked by completing various tasks in each of the game modes.

 * All platinum medals in Mission Mode

Reaching the end of all 4 days in Olimar's Assignment reaches the ending of the Side Story.

 * All Bingo Battle stages

Pikmin 4
The primary ending of Pikmin 4, being the ending that reaches the game credits, involves rescuing Captain Olimar.
 * Rescue Olimar

After returning to the planet to cure Oatchi's tail, a few more areas are left to investigate, along with the final boss battle.
 * Cure Oatchi

Clearing all missions involves rescuing every castaway (and curing all leaflings), collecting all treasures, and obtaining all Onions and Flarlic.
 * Clear all main missions

Besides the things mentioned before, clearing all side missions involves getting all of Oatchi's skills, buying all gear, completing the Piklopedia, getting a platinum medal in all Dandori Challenges, a platinum medal in all Dandori Battles, defeating 1000 enemies, retrieving all of Louie's ingredients, and building all structures. This does not include "Make the World Bloom" and "Grow the Pikmin Population", as these missions renew every time their goal is met and thus can't be cleared.
 * Clear all side missions

The medal obtained in each sublevel of the Trial of the Sage Leaf is recorded, and it's possible to get a platinum medal on all of them.
 * Get all platinum medals in Trial of the Sage Leaf

Dandori Battles from the standalone "Dandori Battle mode" option on the title screen have a few different stages that need to be unlocked by playing the stage before them.
 * Unlock all standalone Dandori Battle stages

On the title screen, there is a "gallery" option that allows the player to re-watch cutscenes. Some need to be unlocked.
 * Unlock all gallery videos

Hey! Pikmin
ending occurs when the Berserk Leech Hydroe is defeated. In order to do this, the player must first collect 30000 Sparklium and reach the end of the Lushlife Murk to unlock the final area, Fragment of Hope.
 * Defeat the final boss

Reaching the end of all 49 areas (including the secret areas, which requires completing some areas twice) and completing all regular Secret Spots will mark every level as being cleared on the area selection menu.
 * Complete all areas

Getting all 125 regular treasures will fill the Treasure Log.
 * Collect all regular treasures

''Hey! Pikmin'' also has 41 amiibo treasures, but the only way to get them all is to have all of the corresponding amiibo, or the Pikmin amiibo.
 * Collect all treasures

Completing the logs requires collecting all 166 treasures, encountering all 57 enemies, and unlocking all types of Pikmin and pellets.
 * Complete the logs

Completing an area "perfectly" will place a gold Pikmin badge on the level's icon in the area selection menu. If this is done for all areas, the saved game selection menu will also have a gold Pikmin badge on that save file. For an area to be completed "perfectly", the following must happen: Once an area receives a badge, the badge stays there forever, and if the player did something while playing an area that made it impossible to get the badge, they can just try that area again.
 * Collect all badges
 * The player must find all 20 Pikmin in the area.
 * The player must never let any Pikmin die.
 * The player must never use amiibo to help.
