Big Bertha (Blaster)

Big Bertha is the upgraded form of a Blaster in the game Super Mario RPG: Legend of the Seven Stars. This cannon fires more powerful Bullet Bills than a normal Blaster and are found in Bowser's Keep. The cannon can also use the special attack Blazer, which can cause instant death for one ally. However, since Big Berthas have such high defenses but low magic defenses, they can be beaten easily by most magic spells, especially thunder.

Trivia

 * The name "Big Bertha" is rather typical for (usually old) cannons, thus giving this Super Mario RPG cannon its name.
 * A certain fish in Super Mario Bros. 3 has the same name.
