There's two that were just suggested recently: Crazy Dave and the Prince of Persia. The former represents the tower defense genre and a classic mobile game, and the other is the progenitor of the cinematic platformer, plus Sands of Time is considered one of the best games of all time.
There's also the Chosen Undead, who's being rated right now, plus Artorias, Solaire, or whoever else could be a Dark Souls rep. It's one of the major definers of the 2010's, codifying the Soulslike subgenre and becoming a measuring stick of brutal difficulty. Lloyd is probably going to be out Bamco rep, but Dark Souls is not to be slept on.
Lastly, Dovahkiin. Elder Scrolls is pretty much the Western RPG, and Skyrim in particular is the most well-known of the series. He's mostly passed over in favor of Doomguy, since the latter got a lot of new developments in his favor while Dovah took a bit of a break, but Skyrim is still another candidate that should not be ignored.
Yeah, Angry Birds isn't what it used to. They took down the original game because it wasn't "profitable enough," for crying out loud! That's the hardest you can shoot yourself in the foot short of something actually morally reprehensible, like with Konami or Blizzard.
