Side-B: Build assist-bot: Tails builds a robot that will move back and forth, firing laser beams. If you release the button early, it will blow up in your face, dealing knockback but no damage.

Customs for his Side-B:

Bomb-Bot: Takes longer to build, but throws bombs, which deal more damage and knockback. Kamikaze: Is quick to build, but blows up upon approach!
