Thunder and Storm are the guardians of the sixth "Your Sanctuary" location in EarthBound, Pink Cloud. As their names imply, their attacks include the ability to use a Crashing Boom Bang Attack (PSI Thunder), as well as summoning a storm. They waste every other turn taking deep breaths, perhaps because they get to attack twice per turn. They can also rush in and intertwine with Ness or the others.
- The music played during the fight is the same music played during the Kraken and Electro Specter fights.
- Storm holds a large palm leaf, which in Japanese mythology is often used by magical creatures as a way to cause storms.
