Bandana Blues are enemies that appear in Super Mario RPG: Legend of the Seven Stars. They are sharks that dress as pirates and they work for Jonathan Jones at the Sunken Ship. They are stronger than the Bandana Reds and serve as Jonathan Jones' personal bodyguards since four of them aid him in battle. After the battle, Bandana Blues aid Jonathan Jones in preventing Yaridovich, one of the members of the Smithy Gang from escaping into the Sea with a Star Piece.
In battle, Bandana Blues act the same as their weaker counterparts and they can only use Pierce as their special move. They can also attack physically with their spears.
Bandana Blues are weak against both fire and thunder moves so Mario's Super Flame and Mallow's Thunderbolt will be effective here. However, if all of the Bandana Blues are defeated first, Jonathan Jones will force Mario into a one-on-one fight with him. This is tad more difficult to fight so it is recommended to keep at least one Bandana Blue alive to avoid the one-on-one battle.
