Terrence is one of the key examples of how I adapted a character's existing combat style to brawling. In this case, obviously, I added elemental stuff (we'll call them "particle effects") to the normal things you'd do in a bar brawl - punching and throwing beer. Also, since Terrence was very much about beer and beer distribution, I made sure that he had powers that varied by beer type. At some point, this could be tweaked into a fun PvP drinking game, in which real-world beers are "relabeled" as the beers listed in the powers. You want the bonus? Bottoms up!
The flavor text for several of the powers is based off of Terrence's outrageous German accent. That player is very fond of outrageous accents, and (as others have noted) one or two players at the table with distinct accents or manners of speaking go a long way toward getting other people to think and speak in-character. For my part, I can't usually maintain a consistent accent all that long, but my current Mage game is distinctly improved by the same player's outrageous Boston accent and Samhaine's outrageous Russian accent.
One thing that I wanted to try with the bar brawl rules, but never quite completed, was to hand out powers that shifted characters over into different combat roles. I felt like my players enjoyed their normal combat roles, but none of them were so attached to those roles that they wouldn't enjoy a one-encounter shift into another role. Variety is the spice of life, as I'm told.
