It seems to have a charge pattern similar to that of the Queen Bee. Players should be advised that this enemy can charge through walls that are at least two blocks thick. As the player fights Mothron, it will lay Mothron Eggs which, after a while, will hatch into Baby Mothrons that have a similar attack pattern to the parent. However, these eggs can be killed before hatching.
- Rarely, while fighting Mothron , it disappears immediately without any drops. This can happen even if its health hasn't been completely depleted yet and its visible in the screen. (May only be for PC)
- Added to the game.
