Crossovers that are totally wicked

[Nerd-o-rama]

1) Sailor Moon meets the Powerpuff Girls

Approved.

2) Any Gundam series meets Full Metal Panic

Char Aznable meets Al and his pilot... then have the Gundam team go looking for Mithril and stumble onto the latest hijinx at the high school with you know who & Co!

...you know, bizarrely, I don't think Super Robot Wars has ever had FMP in a game with UC Gundam. I really want to see the SR Team meet Shiro Amada and the 08th Mobile Suit Team - almost as much as I want to put Sousuke and Setsuna F. Seiei from 00 in a room and see if people are able to tell them apart. Just kidding, Setsuna's crazier.

3) A Power Rangers series that doesn't across as lame... okay maybe going too far there!

4) Symbionic Titan renewed and released on dvd and whatever else medium and if we're at it a new series using the creators notes and not involving a rewrite because they don't know better!

5) A Star Wars series with nothing to do with the Skywalkers, I exclude Han Solo's past because we all want to know how he ended up with a Wookie nanny and because it would be awesome to see this animated and written properly!

6) A Star Trek series based or at least inspired by Star Trek Aegean because its yet to actually start and it holds so much promise (Ideology of Madness podcast for more details on this)

7) Ditto on Knights of Reinsborough although it would have to be more adult rated due to language and violence... quite a bit of it actually!

8) Linnea Sinclair's books being animated especially the Dock 5 series but not so much of the dirty parts okay?

9) A Mass Effect tv series but not centred on Shepherd so we get more background stories perhaps some link to one of the mass effect series so we get a better explanation on why it had to end on such a completely meaningless note. Maybe not then...

None of these are crossovers. Also, there's already a trilogy about Han Solo's backstory in the EU. Look for novels by A. C. Crispin.

10) How about a Gundam series with a Mass Effect style backdrop?
It starts off at a biotic-style academy where they're being taught to use their gifts in symbosis with a new military weapon... the Gundam however the facility is attacked and a number of the prototypes are stolen leaving the survivors under the protection of a neophyte pilot in a modified generic model with most of the teacher's killed in the attack the rest are fleeing aboard a railcart that runs underground and he has to reach the other side and clear the area so they can escape aboard one of the shuttles left there of course the bad guys whose organisation are based on the Greek underworld (Hades) are intent on securing the last remaining biotic pilots but unexpectedly the pilot gets help from members of a band of supposed terrorists who help them escape revealing one of the pilots is the daughter of a member of their group and the reason they were able to escape the facility.
Managing to reach the safety of a Terran base the pilot learns he is being recruited to help fight off a mysterious invader unaware these are his former schoolmates that were taken by Hades are being prepped to move against his homeworld and thats just for starters!

And while technically a crossover, this is still basically every third Gundam series anyway.
