Tonzura Sutakora, also known as Tonzra or Tonzler, operates as the muscular enforcer in the Doronbo Gang under Doronjo alongside Boyacky. His past includes professional wrestling before joining the gang, motivated by plans to fund a wrestling comeback with riches from the Dokuro Stone. Doronjo recruited him by exploiting his enormous appetite and craving to demonstrate physical strength.

He speaks in a Kansai dialect to accentuate his thuggish persona and shows unwavering loyalty by obeying Doronjo and Boyacky's orders without question. Tonzura affectionately calls Boyacky "Boyayan," reflecting their camaraderie. Despite his role as the gang's muscle, he often flees confrontations and depends on gadgets over brute force. His quirks include vomiting when startled due to a weak stomach and performing pelvic thrusts during leisure moments.

Across the original "Yatterman" series and reboot, Tonzura joins missions hunting Skull Stone shards worldwide under Dokurobei's command, consistently losing to the Yatterman and facing punishment for failures. After the gang disbands, he manages wrestling promotions and leads the "WHH" organization, later contradicting his bachelor status by mentioning an adult daughter.

In "Time Bokan: Royal Revival," he reunites with Doronjo and Boyacky for a villainous trio race using the Kitchenbot, narrowly defeating the Akudama Trio before enduring Dokurobei's immediate punishment. The gang later battles superheroes like Gatchaman and Casshan, losing when the Yatterman intervenes.

Tonzura appears in the 2009 live-action film with amplified eccentricity and strength, casually hurling cars while maintaining close ties with Boyacky. In "Yatterman Night," set generations after his era, his legacy endures through Elephantus, who adopts his alias and rebels against the Yatter Kingdom.
