Gustavo Mota, I picked him for every heist every since the 1st one I picked fell off his bike with 2 mill on his back.
He is my favorite character because he says "you know what I'm sayin" all the time and his voice is too funny.
LOL I do.
His explosive personality is hilarious. I never lmao'd so hard. xD
Mine is also Trevor for the above reason.
He's so unpredicatable that it's hilarious. His whole moral compass is upside down but right up at just the right times that makes him so hilarious. Then you have his weird tastes in women, men, drugs, and seriousness. And his explosive personality makes for some hilarious cutscenes in the story, side missions, and rampages.
