Which anime protagonist would struggle the MOST if they were suddenly dropped into another anime’s world?

Not because they’re weak, but because their abilities, personality, or way of thinking wouldn’t work well in that world.

For example: Luffy from One Piece in Death Note — imagine him trying to survive a battle of intelligence against Light and L. 🤓
Subaru from ReZero in Hunter x Hunter — he’d have to survive in a world full of ruthless fighters and unpredictable abilities. 💀

I’m curious about matchups where a character’s usual advantages suddenly become a disadvantage.

Which protagonist would have the hardest time adapting to another anime’s world, and where would you send them? 👀
