Welcome to my new, and hopefully improved, idea collection. These ideas are either gonna be done by me, or if someone is interested in doing them, ask me first.
Let's start like we did last time, with some Rooster Teeth stories
Into the Rooster-verse!
After the events of season 17, Simmons has managed to recreate the portal guns, but instead of traveling through time, they instead go through alternate realities. Of course, this leads to unforeseen problems, putting the multiverse in jeopardy. Now the Reds and Blues, along with some friends they made in the other worlds (mostly because there's no way they're trusting the Reds and Blues to fix this themselves) must save the Rooster-verse! (Crossover between Red vs Blue, RWBY, Gen:Lock, and any other Rooster Teeth show)
A Blue Idiot in Arkham series
Caboose somehow finds himself in the Batman: Arkham series, and everything goes off the rails
A Blue Idiot in Arkham Asylum
Caboose finds himself in Gotham City on the night Joker takes over Arkham Asylum, and he decides to help his new pointy-eared best friend stop the mean clown. Can Batman survive this night with his sanity in check? Not just from the Joker's scheme, but from keeping himself from killing this blue armored idiot?
A Blue Idiot in Arkham City
When Bruce Wayne decides to investigate Hugo Strange's Arkham City, he knew it wouldn't be easy, even worse when Alfred decides to send him some 'assistance', Caboose! (Because there's no way in hell is he being left alone with this blue idiot.)
A Blue Idiot in Arkham Origins
An attempt to bring Caboose back to his home universe instead results in Caboose being sent to Gotham years in the past. Can the younger Batman survive Black Mask's bounty on his head while being followed by this blue idiot who claims to be his friend? Can present Batman get Caboose back before he accidently destroys the timeline?
A Blue Idiot and the Arkham Knight
On the day a way to send Caboose back to his home universe is found, Scarecrow begins to terrorize Gotham with a new toxin and a militia led by someone called the 'Arkham Knight'. Despite Batman's efforts, Caboose decides to stick around to help his pointy-eared friend face this threat, and gets the idea to bring the other Reds and Blues to Gotham to help fight the militia and other criminals.
Waking Up in a New World (Version 1)
After using her silver eyes on the leviathan Grimm, Ruby wakes up to find herself back in Beacon in her second year. How she's back in Beacon is just one of the many questions she has, like: Why have their bunk beds been replaces with two queen size beds? Why is Weiss being much more affectionate? Why are Yang and Blake bring so flirty? and why is Ren suddenly a girl?!
Waking Up in a New World (Version 2)
After using her silver eyes on the leviathan Grimm, Ruby wakes up to find she's in a different world, where Grimm don't exist, her friends are in high school, there's no aura or semblances, everything is normal. But one question: Why is she a baby?!
Death Battle: The Consequences
Of course all the deaths in 'Death Battle' are non-canon, but let's think for a second if they were. What if the Mushroom Kingdom had lost it's heroes to a hedgehog and fox? What if Equestria had lost it's Princess of Friendship? What if Splinter found out he lost three of his sons after they killed each other for no reason? What will the Thundercats do after losing their Lord? Who will stop Voldemort now that the 'boy who lived' is dead? Maybe this will give you answers?
RWBY vs. JNPR: The Vale Gulch Chronicles
RvB AU of RWBY, in a deserted canyon, two Red and Blue teams, codenamed RWBY and JNPR respectively, have absolutely nothing to do. But things change when RWBY 'captures' one of JNPR, leading to them to calling for reinforcements.
The Biker Girl and the Bookworm
AU, Blake's attempt to have a quiet afternoon reading in a café is ruined when Biker chick Yang decides to 'kidnap' her for a cross country road trip.
A Stray finds a Home
On the run from the White Fang, Blake is found by a certain blonde who takes her home to Patch, where she meets the blonde's cape wearing sister, loving father, drunk uncle and little furry monst-I mean dog.
And now for something completely weird...
The Crossed Days of JNPR
After the dance, Pyrrha comes to a shocking realization: she loves seeing Jaune in girls' clothes. Soon, JNPR's leader finds himself trading in his pants for a short skirt as Pyrrha forces him to crossdress. This leads Nora to realize she too loves forcing Ren to wear girl clothes, and soon both JNPR girls get into a rivalry to prove which boy makes the cutest and sexiest girl, much to Jaune and Ren's humiliation.
Author's Notes: Yeah, my mind goes to strange places sometimes. Tell me what you think of these or if you are interested in any of them.
