Crossovers or just plain cross
Unintended crossovers
Cyborg…009
Victor Stone stared at Joe Shimamura and chuckled "Dude, aren't you like seventy?"
Joe was also smiling "Yeah but at least I'm wearing clothes!"
Chuckling the younger man replied "Got me there."
Cyborg shook hands with Cyborg Serial Number 009.
Animorphs
"So let me get this straight," Beast Boy said while not blinking, not moving really, "You guys got your abilities from an alien so that you could fight other aliens who are taking over the world by entering people's brains?"
The five people around him, Jake, Marco, Cassie, Rachel and Tobias looked at each other…well four people and a hawk nodded before they all looked at the rest of their respective teams and pointing at the other group…wings included.
In unison they whined "They've got a cooler back story!"
Darkness
The elf in front of her bowed low "My name is Drizzt Do'Urden, Dark elf, yes but I have forsaken the ways of my kin."
Raven allowed her powers to fade as she bowed, a respect the drow had earned "Raven Roth, daughter of the demon Trigon. You would probably know him better as Scath."
The drow nodded "Scath is known to my people but he has never been summoned. He is far too powerful." Drizzt's eyes were on her as his hands tried not to move to his scimitars.
Allowing her hood to fall she said "We have both forsaken our heritage."
Grey/Gray
"You're named after a dong!" Fullbuster snarled.
Robin slammed his forehead against the mage's "You're named after a non-descript color!"
Gray snorted "At least I'm not dressed like a stoplight!"
"At least I'm wearing clothes!" the leader of the Titans growled.
Two voices from the back of the room, one a green shape shifter and the other a fire dragonslayer agreed "Related."
Cooking
Makito Koenji leered at the princess before asking "What's your name?"
Smiling Starfire said "Koriand'r"
The curry chef blinked "Coriander?"
The significant other, one a high school girl and the other a stoplight, growled "Not the same thing!"
Unexpectedly Cross
Citrus
Robin knew a lot of things made him angry, villains-Slade in particular, dishes in the sink, radios turned up too loud, people hitting on Star. But even with those many things nobody would have guessed that orange juice and Sprite made him angry…
Bent
Starfire's stuffed animal collection was in a very specific order. Not only that but specific poses and the angles at which the arms were held was subject to measure by a protractor. The usually relaxed princess would turn more violent and spiteful than her sister if her subjects were touched.
Blueprints
Blueprints were something that Cyborg enjoyed, they were the finished product put on paper so that they could be shown to others before the project even started. Usually. There was one set of blueprints that were never mentioned, never even looked at. His own.
Gems
Raven and jewelry had a very twisted relationship. She liked jewelry but hated the one word associated with it 'gem'. everyone agreed it was a reasonable dislike. Much later anyone who related her to one was instantly faced with a rather angry Raven and when they asked why she would reply "You're trying to flirt with me and you don't even know that?"
Music
There were actually many secrets that Beast Boy kept, most would be shared if one asked the right questions. Into that category was how many CD's he had. The sheer number was something of many bets, the highest number was 2,000. The real number was closer to 2 million. Beast Boy adored every song of his collection from Demon Days by Gorillaz, to The Tower by Vulture Industries and The Deceiver of the Gods by Amon Amarth along with Million Mile Reflections by Charlie Daniels. There was only one other person aloud to touch it and that was Raven because a) she appreciated music nearly as much as he did and b) she was his girlfriend. Anybody else was asking for a beating by a very angry shape shifter.
For those of you who don't know what specific cross over I did here's the list: Cyborg 009, Animorphs, Forgotten Realms, Fairy Tail, Addicted to Curry.
