We made the first stage of the battle with the Crystal Boy (CrystalBoy, Crystal Bowie, Lord Necron) - the main boss of level 4-3 and only the 4th episode.

The battle takes place in two stages:

1st stage: Crystal Boy is protected by a bulb and flies, throws bombs and chases the player, trying to hit him (a rotating satellite makes it difficult to pass). The transition to forced mode occurs when the number of hits is from 40% or less: the pursuit accelerates, the throwing of bombs becomes more frequent, the satellite spins up faster, its maximum flight radius increases. At this stage, all playable characters can beat the boss (Dominique is preferable here, since she has the strongest shot).

2nd stage: After the player destroys the flying unit, the protective flask is neutralized, and the Crystal Boy begins to fight on foot. At this stage, he can: walk, squat, jump. It can shoot two types of weapons - shoot a claw (strong damage to the player) or shoot a laser (weaker damage). He can also jump onto crumbling platforms and fall off them if the player forces him to do so. Here only Cobra can defeat him, but more on that later.
