What are the possibilities and features of a Doctor Who and Homestuck crossover fanfiction?

There are many potential scenarios. Maybe a time anomaly brings the Doctor to Broadchurch, or a character from Broadchurch stumbles upon the Doctor's TARDIS. The story could explore how the two very different universes interact and the challenges that arise.

Well, one possibility is that the TARDIS lands in a Pokemon tournament and the Doctor has to use his wits to solve a mystery related to it. Maybe there's a time anomaly affecting the Pokemon battles. Another idea could be that a Pokemon gains time-travel abilities and the Doctor has to help it control them to prevent chaos.

There could be lots of possibilities. Like exploring different timelines and powers. But a challenge might be keeping the characters' personalities true to the originals.

There could be exciting possibilities like combining the advanced tech of Star Trek with Doctor Who's time-travel adventures. But the challenge could be keeping the tones and characters of both shows consistent.

The possibilities are endless! You could have the Doctor and Crowley teaming up to save the universe or Aziraphale getting caught up in a timey-wimey adventure. However, challenges could include keeping the characters' personalities consistent and not overcomplicating the plot with too many elements from both shows.

The possibilities are endless! Maybe the Doctor could time-travel to a moment where the Legends are facing a temporal crisis and offer his unique skills to help.

One scenario could be that the Legends accidentally land in a Doctor Who universe and have to team up with the Doctor to get back home. Another could be that a powerful force is threatening both timelines, forcing them to collaborate.

There could be all sorts of fun scenarios! Maybe the Doctor lands in Invader Zim's universe and has to help him deal with some crazy alien threats.

It could be really exciting. You could have characters from both universes interacting and facing unique challenges together. But it might be hard to balance the different tones and lore of the two shows.

The main feature is usually the combination of the two universes. You might see characters from both 'Numbers' and 'Doctor Who' interacting in unexpected ways.
