I've got five minutes to type all of these down, so here ya go! And also, they aren't all actually shows/movies. Some are historical happenings that I thought would be cool.

The List:

Hetalia: Axis Powers

Cold case

Powerpuff girls Doujinshi (the well-known one)

Titanic

Twin Towers

Fruits Basket

Loveless

+Anima

City of Ember

The Fallen

IMPORTANT!:

Titanic: with this, you would need to get clockwork to put Danny in this time, and have him do something to change the timeline

Twin Towers: similar to Titanic. Clockwork puts Danny back in time, and has him change something.

Hetalia: with this, you could make Danny a country called Ghost Zone, but that's just an idea. Use it if you want. You can make your own storyline though.
