Daimaru "Chubby"

The burly, heavy-lifting coal stoker inside the wooden giant mecha Steamer Benkei from the "A Tale of Two Robots" segment. Daimaru is the physically largest member of the ragtag crew. While Denjiro manages the general fire and steam pressure, Daimaru uses his immense strength to physically lift and heave heavy fuel loads into the furnace. He and Denjiro form a classic boiler-room comedy pair. While Sankichi panics and screams nonsensical combat commands from the upper pilot deck, Daimaru and Denjiro bear the brunt of the extreme exhaust heat and physical exhaustion down below.
