The player character of Wing Commander 1&2 is supposedly same as "Maverick" Blair in 3&4, so that being my favorite series makes him likely.
Monkey Island being another favorite, Guybrush Threepwood is high. But despite replaying at least one MI almost every year, that may not make huge hours.
Other than that there's no obvious option, as I haven't played that much Marios, Sonics or Zeldas.
Of those Sonic would be top one, but I don't expect to get in my top 3. But Sonic may win by standard of "character in most games I've tried at least once" (largely due Sonic Gems collection on PS2 - and my general emulation history).
Anakin Skywalker/Darth Vader is likely in my top 5 - at least in number of games if not hours - with LEGO Star Wars games, Episode 1 Racer (two versions) and Battlefront II.
I have played at least three Spider-Man games, plus him in Marvel vs Capcom series.
Then there's Indiana Jones, with the old Lucas adventures, Infernal Machine and LEGO.
In hours, makes me wonder if I've played so much Civilization or other historical strategy games that some historical person could win? Caesar, perhaps?
And having played lots of driving games, maybe some classic car might be my most played "character", like Dodge Viper. Or due numerous rally games, Lancia Stratos or Delta, Toyota Celica or Subaru Impreza.
