Self-Mobility

Self-Mobility is an attack style characterized as a form of mobility that involves the tower moving to different points of the screen at any given time without player input. It is part of the damage types family.

Self-Mobility is characterized on the Bloons Wiki as, the upgrade icon for Pursuit in Bloons TD 6, because it is a core upgrade that demonstrates a tower moving without player input.

Self-Mobility is a behavior that does not involve the need to use user input to manually set where the tower attacks on to which location and from which angle, unlike Aim-Based Mobility. Although Self-Mobility is a subset of Tower Mobility, it is not the same because the tower is constantly moving at all times. However, it shares the core intentions its Superset which is to describe a tower's capability to become "mobile".

Monkey Ace always have Self-Mobility as a base tower.

Heli Pilot doesn't get Self-Mobility until Pursuit is bought.

Although the main tower of Carrier Flagship does not have Self-Mobility, it's mini-planes do.

Sniper Monkey is considered a mix of Full Map Range and Snipe  rather than Self-Mobility, even though it does not require player input to exercise its attack style. This is because the Sniper itself doesn't move to a different location despite having the long-ranged capability to target anywhere on screen, but rather it targets anywhere on screen very quickly.
