Angry he grew to a giant size and tried to smash them with an electrical tower. Mushashi became Ultraman Cosmos and a sumo match began with the two. After one round he gave up so he could get a drink of water. It began again and Cosmos, with the support of his teammates.

- Kappa is based on a Japanese creature said to live in lakes and pull people under. They enjoy eating cucumbers, and carry a little water on their foreheads. They will always bow if bowed to, and if they spill their forehead water they will be paralyzed. If their head water should be refilled, they will become the person that refilled its servant.
- Kappa may be a tribute to King Kappa from Ultraman Ace.
- The final battle between Ultraman Cosmos and Kawanoji is also a reference to Ultraman 80's battle with Jihibikiran. In both occasions, Ultraman 80/Cosmos challenged Jihibikiran/Kawanoji to a sumo wrestling match, on the condition that the monster will revert back to their normal selves if the Ultra wins.
