Raoul

Raoul (ラウル) is an anime-only character. He owns a bar at Loguetown called Gold Roger. In his youth, he used to know Gol D. Roger, who visited his bar and told him he will conquer the Grand Line.

Past
Gol D. Roger and his crew once visited Raoul's bar before venturing to the Grand Line. Raoul tried to warn Roger about the dangers of the Grand Line, but Roger was more excited than deterred.

Raoul was present during the Pirate King's execution.

Loguetown Arc
When Smoker was in charge of the Marines stationed in Loguetown, no pirates visited Raoul's bar and Smoker became his only customer. When Luffy came to the bar by coincidence, Raoul told him about Roger's exploits.

After Luffy left, Smoker visits the bar for a drink. Raoul wasn't pleased with Smoker's presence.
