Battle Windows (referred to as "Computer Virus" in the English version) is a boss fight in Kirby Super Star that appears in [[KSS:GCO|Great Cave Offensive]], [[KSS:MWW|Milky Way Wishes]], and [[KSS:The Arena|The Arena]]. Battle Windows is known for being an RNG-heavy segment in speedruns. It is a turn-based fight, similar to an RPG. Battle Windows enemies will only be vulnerable while they are not attacking Kirby, and Kirby has a limited amount of time to defeat it during his turn.


Battle Windows has a chance to spawn [[KSS:Copy Essence|Copy Essences]] during Kirby's turn. These abilities currently do not have any implications in the run, as Kirby immediately loses his turn upon obtaining one.

In Milky Way Wishes, a small amount of time can be saved by selecting abilities as Battle Windows text is scrolling. Text does not stop scrolling while Kirby's ability animation plays, so this time spent waiting for text scrolling can be spent while simultaneously watching Kirby's ability animation.

During the first turn of each Battle Windows enemy, there is a 25% chance for Battle Windows to attack first. This is a notorious point of chance in the run where time can be lost if Battle Windows gets the first attack.

When Battle Windows attacks first, time loss can vary depending on the attack that is done. The worst possible luck is having an enemy shield on their first turn, which requires a whole additional turn to defeat it.

In specific circumstances, it is actually beneficial to have Battle Windows to attack first, but this is typically only done in TAS. An example of this is using Suplex while fighting Red Dragon. By having Red Dragon attack first, Kirby can grab its scratch attack and defeat it in one turn.

Every Battle Windows enemy has two attack pools to choose from, which is based on if RAM value 179C is an even or odd number. This number changes between 0 and 1 after each time Battle Windows attacks, first starting on 0.

When it is Kirby's turn to attack, abilities have a chance of appearing on each side of the screen. Several random numbers are used during this process. This calculation is different from power calculation in The Arena rest area.

If an ability does not appear, RNG advances by 1, while if an ability does appear, RNG advances by 3. RNG can advance at least 2 times or at most 6 times when calculating powers (unless under a specific circumstance, [[#ability-circumstance|see notes below]]).
