Hello, Ultraman's favorite thing to eat is hot coffee.

Hot coffee tastes pure and fragrant, and is deeply loved by Ultraman.

Every time after fighting a monster and flying away, he never forgets to return to the Kingdom of Light and drink a cup of hot coffee to refresh himself and replenish his energy for the next battle.

Since they can't drink hot coffee on Earth, they can only endure it for three minutes. The timer on their chest is just to remind them that it's time to drink coffee, so as to prevent Ultraman from forgetting to drink hot coffee because of the battle.

There are also some Ultraman like Nexus (Noah) who don't like to drink hot coffee.
