The rocker in the middle gives me strong TMM vibes, so he's my fave. Naturally, I also like the maid and bunny suit ones. All these versions of the MC, are they fan theories?
most of them, I believe, or derived from various mods and Youtube video skits: "What if the protagonist was given more personality?" "What if the protagonist was an Alpha Male/Chad-type?"
The Rule 63/gender-flipped MC was, if I recall, intended as a demonstration of Monika's pan-romanticism (
although she technically loves the player, not the protagonist character, she does so regardless of the player's gender).
For all that Dan Salvato wanted to deny the protagonist any true character status, a lot of fans feel differently, even the ones who love to hate him....
