Well, it can be subjective. If you're a big fan of Xander and the BTVS universe, and the idea intrigues you, it could be worth a read. But if you have specific expectations that don't align with the 'bad idea' aspect, you might be disappointed.
First, the plot could be tightened up. If there are parts that seem to drag or don't contribute to the overall 'bad idea' concept, they could be removed or rewritten. For example, if there are too many side characters that don't really affect Xander's journey in the fanfic.
Well, it could be the character development of Xander. Maybe the fanfic takes Xander in a direction that is different from the norm in the Buffyverse. It might show his flaws more prominently or put him in situations that force him to grow in unexpected ways.
One common theme is the fish - out - of - water concept. Xander, coming from the Btvs universe, is suddenly in the Dragon Age world, so he has to adjust. Another theme is power and how Xander's existing skills or lack thereof play out. For example, his combat knowledge from Btvs might be useful but also not enough in the more complex Dragon Age battles.
One way the story could be developed is that as a girl, Xander might face different challenges in the time - travel adventure. For example, in the Buffyverse, gender often plays a role in how characters are perceived and treated. She could use her new perspective to change events in the past or future. Maybe she'd have a different relationship with the other characters, like Willow and Buffy. She could be more empathetic or perhaps face more discrimination depending on the time period she travels to.
In this fanfiction concept, Loki's actions in marrying Faith and Xander could be part of a larger plot. Maybe he wants to use their combined powers or connections in the Buffy world for his own gain. Faith's slayer abilities and Xander's knowledge of the supernatural world might be valuable to Loki. And for Faith and Xander, this marriage would be a huge adjustment. They might initially resist but gradually find some common ground as they face the challenges that come with being Loki - bound.
Sure. One great Xander btvs dragon age fanfiction is 'Xander in Thedas'. It combines the unique charm of Xander from 'Btvs' with the rich lore of 'Dragon Age'. Another one could be 'Xander's Dragon Age Adventure' which has an interesting plot where Xander gets transported into the Dragon Age world and has to adapt to survive.
It's bad because Pokemon is aimed at a wide audience including children. Introducing drugs into fanfics would corrupt the positive and innocent nature of the Pokemon world.
A really cool plot twist might be that Xander, as a girl, travels back in time and falls in love with a character who is an ancestor of one of her friends in the present. This would create a moral and emotional dilemma for her. Also, she could find out that in this different time period, there is a prophecy about a female figure (her) that is related to saving the world from a great evil. So, instead of being a sidekick - like character as she was as a male, she becomes the central figure in the time - travel adventure, which is a huge change from the original Btvs storyline.
