So how do y'all feel about a Dark Souls character? It's one of the most important new series of the 2010s, receiving widespread praise and "Soulslike" becoming it's own new genre. It might not be completely clear on who would be chosen as a fighter, but it does have multiple valid candidates.
Both of the knights at the bottom (Dark Souls II Protagonist "The Bearer of the Curse" and Dark Souls Protagonist "The Chosen Undead") and the knight making the Y pose ( Solaire of Astoria) could functionally all be alternate costumes of each other since they share similar abilities and fighting style. The only real difference is that the protagonist are silent and solemn, while Solaire is jolly and chatty.
The knight at the top-left is Artorias, who got a bit of a spotlight due to the infamous "Google Leak", but still would be a valid choice due to being a
Very Popular boss in a game series most noted for it's boss battles. An entire DLC expansion was dedicated to Artorias, he is kind of like Monster Hunter's Rathalos if he was player character sized. Plus he's got a badass wolf companion.
