I'm not entirely sure specifically what this 'marik and bakura visual novel' is about.

Well, if 'marik dark duel stories' is related to a card game, perhaps Marik has some unique and powerful cards in these duels. The 'dark' part might imply that the duels are not just about winning but also about some sort of moral or psychological struggle. For example, he could be using cards that have a darker side to their abilities, like cards that can drain the opponent's energy or cause negative status effects.
Well, it's hard to say without reading it, but it could be Yugi. Yugi often plays an important role in stories related to Marik as he has a connection to the Millennium Puzzle and is a powerful duelist. He might be involved in trying to help Anzu break free from Marik's dark half grip.
Well, a fanfiction about Joey in love in 'Penguins of Madagascar' could be really interesting.

I'm not sure specifically which 'friends scary joey story' you mean. There could be a lot of fan - made or less - known stories within the 'Friends' fandom involving Joey. It might be a spooky story someone created about Joey's acting experiences, like a horror - themed role he got involved in on the show that had some strange happenings behind the scenes.
It's tough to determine exactly who Joey is based on just this. He could be the friend who initiated the adventure involving the backpack, or perhaps he's the one who faces challenges because of it. More information would make it clearer.
Joey could be an ordinary citizen who just happens to be in the wrong (or right) place at the wrong (or right) time and meets the Batfam. Maybe he's a journalist trying to get a scoop on the Batfam and ends up getting more than he bargained for.
To develop Joey further, he could be given his own internal conflict related to being impressed by the 'Cinderella' character. He might struggle with his own status or reputation and wonder if it's okay to support someone who is so different from his usual circle. This internal struggle would add depth to his character.
