Spawn

Spawn is an attack behavior characterized as "simply appearing", or more specifically, the spawning of an attack as if it has been teleported from the tower onto the map. It is part of the damage types family.

Spawn is represented on Bloons Wiki as, the upgrade icon for Exploding Pineapple in Bloons TD 6, since an Exploding Pineapple is always deployed onto locations where the Ace was located at during deployment. Spawn is a behavior that is distinct from projectile-specific behaviors such as Area of Effect. It is not the same as Whole Screen because Spawn spawns a projectile in the middle of nowhere and does not do any global effect. On-Track is independent from Spawn, but they can sometimes coincide with each other. Lobbing is not considered Spawn and will never coincide in the same attack, because lobbing is a visual act of an attack leaping over obstacles (sort of like Cabbage-pult from Plants vs Zombies). Spawn does not need Ignore Line of Sight because it is independent from it; the attack just "spawns". Spawn also is not the same as Snipe, as Snipe involves the use of shooting an invisible projectile rather than letting the projectile magically appear from nothing into any visible in-game form without trajectory movement. Spawn is also not the same as Zone, as Zone is for attacks integrated within the tower's own location, and Spawn is for generation of an attack.

Typical examples with Spawn include Exploding Pineapple pineapple bombs, Bomber Ace bomb arrays, Wall of Fire, all Monkey Bank functionalities, Marketplace bananas and other auto-income sources like Merchantman. If a projectile is visibly moving from one location to another in terms of the screen's X and Y axes as it makes the attack, such as Banana Farm bananas, Cleansing Foam foam blobs, or Mortar Monkey explosions, then that is not considered Spawn. Quincy's Level 10+ Storm of Arrows ability is considered Spawn because the initial attack places an abstract area-of-effect on where the attack is placed.
