Powers and Abilities
Bowser is a heavy weight fighter, utilizing he massive size and intimidating stature to plow into his opponents. Bowser also has the ability to shoot fireballs from his mouth. These fireballs can range in strength, and can even explode into a shower of fireballs if shot into the air. Apart from his fire breath, Bowser has also been seen to use power-ups identical to the Mario Bros., such as a metal mushroom. Once ingested, Bowser transforms into a steel tyrant and becomes practically invincible to all attacks. The only thing which is able to break through Bowser's metal coating is a strong and heavy blow capable of shattering steel.
