This boss is a large, fire spurting, pulsing lion-like head made of solid iron, who enlists the help of huge stone hands in battle. Ironsider is one of two bosses that is impervious to Wario's punches, with the other being Red-Brief J.
Ironsider has two attacks. The first one sends out multiple shockwaves towards Wario's way, much like other bosses. Ironsider's second attack is a fire breath attack. The boss will sweep the entire area with the flame. Even if Wario runs away, the flames move faster than Wario can run. The only way to avoid this attack is to Ground Pound and get stuck in the sand in the arena. The flames will then pass harmlessly overhead. Ironsider's hands cannot directly damage Wario. Instead, they opt to hold him in place to be punished by one of Ironsider's attacks. The player needs to shake the Control Stick to break free. Also, Ironsider's attacks will destroy the stone hands if they hit them.
The only way to hurt this boss is to stun one of the hands, grab it, and either throw it at or piledrive near Ironsider. Hitting Ironsider five times will defeat the boss and give Wario access to the Sparkle Land boss, Captain Skull.
