Wait for the one pattern (bottom->right) where Botwoon's head passes through the dividing barrier briefly. The extent Botwoon's head passes through the wall varies ranging from almost no damage window up to enough time for 2 missiles. By jumping there is a doppler effect allowing up to 2 more missiles to hit Botwoon. The fight can be sped up by Gate Glitching through the wall and landing lucky hits throughout the fight.

Dev note: It is much easier to miss with missiles, so 10 leniency missiles are added.

Wait for the one pattern (bottom->right) where Botwoon's head passes through the dividing barrier briefly and fire TWO Super Missiles. This takes a long time, averaging two supers per minute.
