Leadain will stay on the center of the screen and swing it's four tentacles, eventually extending them to attack the player directly, all while shooting it's needles in all directions. After the tentacles are destroyed, Leadain will attempt to use it's outer shell to crush the player. After it takes enough damage the shell will explode, leaving only the center. It will extend a tentacle to once again attack the player while shooting pink energy spheres and lasers.

  • Leadain's innards are based of sea urchin gonads, which are prized in Japanese cuisine as sushi ingredients, while its tentacles are a nod on how sea urchin moves using their small suction cups.
  • A human or robot pilot can be seen falling down from Leadain upon its destruction.
