3. Ron Jakowski
Given that Rockstar divulged in the extraterrestrial in Grand Theft Auto V, depicting frozen alien corpses, sunken UFOs, ghosts and even Big Foot, it makes sense for Ron Jakowski to become a protagonist in future DLC. Ron is "best friend" to the deranged Trevor, whose whirlwind antics transform him from happily married man to deranged conspiracy theorist, bringing some light comic relief to the game. For that reason, he deserves to have a starring role in any and all future DLC, as far as we're concerned, and if he does make a re-appearance as a playable character, we'd like to see him accompanied by the dim-witted Wade Herbert, with the duo making up an... interesting partnership. The potential of a storyline based on aliens, or tracking said aliens down, would certainly go down well with many if it were to become an expansion pack one day, if the hype that surrounded the recent discovery of secretive Easter Eggs is anything to go by. Rockstar would be missing a trick if they didn't explore this avenue.
