A robot who encourages Yuichiro and Sunday to shoot at his rotating target in exchange for crystals to win even more crystals or a special weapon.

Crystals (クリスタルズ)
These can be obtained in four ways: by killing a group of smaller enemies, by killing some larger enemies, through Dream Co., Ltd., and by clearing a round.

At the end of the round it must be fought as a boss. Try to destroy the projectile-firing cannons on the front first, then aim for the core. It reappears at the start of the sixth round (but not as a boss), rotates around the screen and fires projectiles at Yuichiro and Sunday from all around.

After this, he will curl up into a ball and fly around the screen, still shooting fireballs at Yuichiro and Sunday. His fireballs can be blocked by Yuichiro and Sunday's shots. After being defeated, he will shrink and fall back into the lava. By catching him, you can get a random amount of bonus points from 1000 to 5000. He reappears in the sixth round, but is blue instead of orange and is much faster than before.

Power Station (パワーステーション)
The boss of the third round. It will move up and down, spewing fireballs at Yuichiro and Sunday, which can be blocked by their shots. Its weak points are the balls in its rotary mechanism. Don't take too long over it, because if you do, it will start moving to the sides as well! It reappears on the sixth round, but spews out Kame instead of fireballs (that's their other purpose), which will fly directly at Yuichiro and Sunday once they've reached their level. It can also go all the way to the top of the screen.

Maiku (マイク)
The final boss of the sixth round. He is protected by a spinning barrier of balls similar to those in Power Station's rotary mechanism, which must all be destroyed before Yuichiro and Sunday can get a clear shot at him.
