Spawn point

The spawn point is the starting area for players in a stage. In multiplayer modes there are two Spawn Points on each stage, one for each team. In Octo Valley, spawn points are called checkpoints and appear throughout every mission.

Description
A spawn point is a large, metallic device with a flat surface on top filled with the ink of the team it belongs to, the surface of which perpetually rippling. When a splatted Inkling's ghost enters a spawn point, Ink bubbles up and creates a new body for them.

Splatoon
In Splatoon, there are three antenna-like fixtures on the outside edge that glow with a pulsing, rotating light the color of the team's ink. The light takes the form of two rotating arrows, the same design as the lives counter in Octo Valley. While an Inkling is respawning, the design will rotate faster.

In Octo Valley itself, the start of every level has a full-sized spawn point. Further checkpoints are simply miniature versions of their multiplayer counterparts; while normal spawn points fit four players, checkpoints are only made for one player, Agent 3. Checkpoints are shut off at first, and are activated when approached by the player, lighting up with the player's ink color and design. Activating a checkpoint will also restore one of the player's lives, if any were lost. They do not appear in boss battles, except for the first mission and the final mission.

Splatoon 2
In Splatoon 2, spawn points are visually similar to the top of a cappuccino machine, with steam spouts and various valves, and have an on-off switch on the back portion. On the top of the spawn point is a black cover with design made of two arrows surrounding a small circle cut into it, showing the ink below. The same design is repeated in graffiti or lights on "spawn" locations that are not the physical spawn point machines, namely at the starting location in Inkopolis Square and the starting / jump point of Salmon Run stages.

In Octo Canyon, the start of every level has a full-sized spawn point. Further checkpoints are smaller and only have three antennae protruding out of them. They are gray until approached, which will activate them and paint them in the player's ink color, showing a "Checkpoint" message at the top of the screen. Reaching the last checkpoint in a level will show a "Final Checkpoint" message instead. Activating a checkpoint will also restore one of the player's lives, if any were lost.

Online battles
In a short pre-battle sequence, all players on a team appear on their spawn points in squid form. They then assume humanoid form and shake off the remaining ink on them. When an Inkling is splatted, whether by an opponent or a stage hazard, they will reappear on their Spawn Point after about four seconds and are able to continue playing. Respawn time can be shortened with the Quick Respawn ability.

A Spawn Point is also a safe space for all players it belongs to; it is protected by an invisible wall through which no enemies or their attacks can go through, including special weapons such as the Inkstrike or Killer Wail. This allows players on the spawn point to splat opponents without being in danger themselves. These features help to combat spawn camping, though a well-coordinated team can still do it by staying in the area outside the spawn point's shield and splatting those who try to leave.

Spawn points can also be Super Jumped to at any time, giving players a way to escape a dangerous situation if no teammates or Squid Beakons are available. However, this leaves the user vulnerable while preparing to jump; it is not recommended if there are opponents in the immediate area.

On top of that, Spawn Points also act as an inked surface, allowing players to swim in it for healing and refilling their ink tank.

Trivia

 * A player holding the Rainmaker cannot enter their own spawn point, instead they will bounce off the surrounding force field as if they were an enemy.
 * In Octo Valley, a Checkpoint does not need to be stepped on directly to be activated; the ground around it also works.
 * According to the Squid Research Lab, the spawn points in Splatoon 2 are a foreign-made model.
 * In the second artbook there's concept art that details how the spawn point from online matches opereate. Their function looks similar to a coffee machine, having a capsule with condensed ink is used, called リスポーション (Risupōshon / Respawn Portion), where the ink is pressed and heated to form an Inkling.
