Texas is a loud, friendly gambler at the craps table of the Hotel Royale, one of the stock characters in the alien recreation of a bad twentieth-century novel.
Texas appears in The Royale. Riker, Data and Worf enter a revolving door standing alone on the frozen planet Theta VIII and find themselves in a casino hotel, built by unknown aliens for the stranded astronaut Stephen Richey from a paperback found aboard his ship.
Texas is one of its fixtures, a big man in a cowboy hat who is always at the tables. He befriends Data, explains the games in a stream of slang and encourages the young woman Vanessa to keep betting money she cannot afford to lose.
When the officers decide to play out the book's ending as the foreign investors who buy the hotel, Data takes up the dice beside him, corrects their loaded balance by hand and wins enough to break the bank.
