Gizmo

Gizmo is the wealthy owner of the casino and boxing ring in Junktown, during 2161. He partakes in numerous illicit businesses on the side, and has several trading partners in the Hub. Due to his aspirations of assuming power in Junktown, he is portrayed as the nemesis of the town's mayor, Killian Darkwater. With Killian gone, Gizmo would be able take over the town unimpeded. The rivalry for power in Junktown between Killian and Gizmo is the main plot point of the Vault Dweller's visit to the town.

Background
Gizmo runs "Gizmo's casino" and often uses the Skulz to do his dirty work. His bodyguard, a master martial artist named Izo, rarely, if ever leaves his side.

Interactions with the player character
After the failure of Kenji's assassination attempt on Killian, Gizmo offers the job to the Vault Dweller if the latter is successful in convincing Gizmo to offer it. If the offer is accepted, Gizmo demands the Dog Tags Killian wears around his neck as proof of the Vault Dweller's success. If this task is completed, Gizmo properly rewards the Vault Dweller and soon begins to completely takeover Junktown.

Alternatively, the Vault Dweller could have had the conversation recorded and presented to Killian as proof of Gizmo's intentions. This would lead to Killian asking the Vault Dweller to aid in arresting Gizmo. Unfortunately, rather than be taken in, Gizmo resists arrest and proceeds to attack Killian, his men and the Vault Dweller.

Appearances in games
Gizmo appears in Fallout as a Talking Head voiced by Jim Cummings.

Trivia
It has been noted that in early designs, the results of dealing with Gizmo and Killian were intended to be less black and white: a victorious Gizmo would turn Junktown into a flourishing trading center, albeit for entirely self-serving reasons, whereas a victorious Killian would gradually become a well-intentioned tyrant, grinding the town slowly into the dust. This original intention never made the final cut, however.
