MMOEXP: Elden Ring before or after his passing
When Blaidd has the appearance of Guts wearing his Berserker Armor If so, I'd guess that would render Elden Ring Runes fan favorite Ranni the Witch akin to Berserk's Schierke? Although this is a bit of an oversimplification, considering that Ranni is one of the most powerful characters from the Lands Between and Schierke is an aspiring young witch, I think it's reasonable when you consider their different relationships with wolf-like men.
I'm no Vaati, but it's evident that Ranni and Blaidd have a deep connection. Blaidd, as far as I'm aware was specifically created to direct Ranni towards her purpose as a potential godlike figure by an unidentified supernatural force called the Great Will. But as Ranni is able to leave the path she was on, Blaidd grows increasingly feral before eventually losing his humanity entirely when she has finished the plot.
Schierke On the other hand, becomes one of Guts his companions following the destruction of the Band of the Hawk. She soon emerges as the only one who can help him manage his primal instincts while being influenced by the Berserker Armor. This is why Schierke and Guts become inseparable during battle The young witch frequently astral-projecting her soul into his mind to calm his mind and keep him from falling to the armor entirely.
Elden Ring players have drawn parallels between Griffith's iron mask and that of Prisoner class players who can pick at the start of the game. It's not a 1:1 reference though, however cheap Elden Ring Runes the mask's eye covering that is worn by the Prisoner matches the fact that Berserk seldom shows a face-to-face Griffith in his mask. He prefers to depict the tortured mercenary with the one eye obscured through the mask's shadow.
