A hunter of bounties operated as a member of the Bounty Hunters' Guild in the era after the Galactic Civil War and in the initial period of the New Republic. This large and violent hunter was present during the gunfight on the world of Nevarro when the Mandalorian Din Djarin made an attempt to escape, taking the Child with him. He fought alongside the guild's leader, Greef Karga.
The bounty hunter was an occupant of the Nevarro cantina at the time when Din Djarin came back from the planet Pagodon. He watched Djarin as he exchanged his various bounty pucks with Greef Karga.
Sometime after this, he became part of Karga's group, along with other guild members, as they tried to prevent Djarin from leaving the planet. The bounty hunter was positioned next to Karga as he tried to convince Djarin to give up The Child. The Bounty Hunter had his large blaster pointed straight at the Mandalorian during their conversation. He was involved in a gun battle with Djarin, however, he was ultimately shot down by other Mandalorians who showed up to help Djarin.
The bounty hunter carried a sizable blaster rifle and wore large, protective gauntlets covering his hands and arms. He also wore a long, dark robe, heavy combat boots, and a breath mask.
The bounty hunter made his debut in Chapter 1 of The Mandalorian television show by Jon Favreau, which was directed by Dave Filoni and originally broadcast on November 12, 2019. The character was played by American actor Dominic Pace, and the name Gekko was given to the bounty hunter by make up artist Brian Sipe in a post on Instagram. In November of 2020, the bounty hunter was featured on a sketch art card by The Topps Company.
