"Hope you'll stay close."
-A Reacher, Super Mario RPG: Legend of the Seven Stars
Reachers are skeletal ghosts who inhabit the Sunken Ship in the game Super Mario RPG: Legend of the Seven Stars. Reachers are possibly one of the creepiest ghosts on the Sunken Ship, as they resemble large, sad, humanoid skeletons whose bodies are obscured by tombstones. Reachers attack by reaching towards a party member (hence the name) with their long skeletal arms. They can also attack by hurling a large bone (similar to Dry Bones) or by singing a haunting lullaby which will prevent a party member from using magic.
Considering Reachers have high HP, attack, and defense, it is probably wise to use magic or Pure Water on them. Like most powerful enemies in Mario RPG, only one Reacher will appear at a time in battle. This one Reacher will always aid other ghouls in combat.
