Hernandez

Hernandez is a seedy-looking Mexican man with slick hair. In 2161 he lives in Junktown and spends most of his time in Gizmo's casino. He asks the Vault Dweller for money, having supposedly discovered how Gizmo runs his tables and developed a sure-fire system. He considers Gizmo a visionary.

Appearances
Hernandez does not actually appear in Fallout, but his dialogue file can be found in the game's files.

He was in my Fallout game. He asked for 100 caps and promised profits. When you come back later asking for your money he grows angry and attacks you. After beating him you game 130 caps (your 100 and the 30 he had with him)
