A/N; I don't own any of the mentioned Marvel OR DC Characters. This was an idea that was tumbling round my head for a while, I'm a big fan of Nightwing and Dick Graysons Robin. I'm also a big fan the Avengers and I decided to throw the two together, this opening chapter is more set-up and explanation of his presence rather than juicy interaction and stuff, which I PROMISE we will get too.

Transdimensional villains always had this little quirk that Dick hated, they got an almost perverse satisfaction from throwing heroes across a broad spectrum of realities. Dick had been fortunate enough as Batman's sidekick and in his few years so far a Nightwing, to never have experienced the aforementioned vacation to some alternate earth. Apparently however, that luck was going to end.

Meanwhile…

Tony Stark and Bruce Banner were once more playing with science's that two already altered beings should not mess with. After learning about Jane Fosters Einstein-Risen bridge theories from the physicist, and the existence of the BiFrost from Thor, playing with radiation and gateways to other worlds was just too appealing for them to pass up. Mainly so Tony could have something else to gloat about in field he was hardly experienced in.

Had Bruce not been curious about it as well, he would've called the billionaire cruel for trying to steal the glory from the young female norse-god loving scientist in the lab below them, but he was curious and apparently curious scientists are like bitchy competitive teenage girls.

The resounding boom on the other side of the lab however as they flicked the necessary switches on the emitters told them one thing. They had definitely attracted something, but not through the make shift gate of their own design…

Back with Nightwing..

Dick felt the foot lodge in his gut, and then felt a mind-bogglingly good sensation as his molecules were thrown through universe separating barriers. He had always assumed this made people nauseas, or injured them. Not gave them some of the best sex of their life, while clothed. He would've continued to enjoy himself but like most good things, the bad things had to come and ruin it. This bad thing just happened to be a white tile floor, his body smacking into it with enough force that he almost bounced. Almost.

"Bruce, why is there a man wrapped in a black body suit on my lab floor?"

"I have no idea Tony."

Nightwing forced himself to his feet, ah, there was the nausea he was waiting for. His eyes drifted around to the two men in front of him, his lenses flickered back into life in his domino mask and his hand moved toward one of his Nightwingarang' holsters on his belt. He really needed a better name for those things. Witty monologue aside for now Dick, probably alternate universe crisis here. He was about to question his surroundings, but just as his fingers met the pouch he realized his mistake. His Bat-sense had been tingling, the cocking of a pistol behind his head and calm feminine voice behind him settling his fears as fact. "Don't….move." Shit.

Natasha Romanoff's gun was gauntleted by both hands and pressed against the intruders right shoulder. A wounding shot, which they were both aware of. It would keep him alive and useful, but injured and slow. Normally this would lead to careful dance between two veteran fighters with words, acrobatics and one of them going down, but apparently other parties present had better ideas.

"I'm going to go with….dimension hopping superhero." The smaller goatee'd man wiggled his eyebrows, sauntering across the room as he spoke. "Coffee? Thor always has coffee after one of those trips. Apparently it takes it out of you. If ya know what I mean." Hi rambling ended with another suggestive eyebrow wiggle, handing the now open mouthed hero a mug as Natasha pressed him down onto a stool, gun still pressed at his back. She'd let the geniuses work at this one, she'd just wait for any lies.

"How did you…" Dick barely got a word out before the other man in the room, a rather ruffled looking older man made his way across to a computer screen and tapped away at it.

"That, actually makes sense Tony." He tapped away again furiously. "Our gateway may have acted more like a beacon, this guy hits the switch on his end and gets dragged here.." He mumbled onwards as the pieces clicked together for Dick. Who decided to interject, these men were obvious geniuses, and were apparently quite used to mind-blowing stuff going on around them.

"Jarvis, please make the following announcement? All Avengers to Stark lab Beta 1." The goatee'd man spoke to the air, for a crisp, Alfred sounding butler voice to sound from a speaker. "Of course sir." There was an almost supermarket like 'bing-bong' before the same English voice repeated the requested announcement.

"Avengers..? Wait. Stop." Dick took a sigh and finally put the mug down. "You guys were intentionally playing around with dimensional gateways…?" As the goateed man replied with a quick 'Well of course' and the other mumbled, Dick couldn't help but slap a shaky hand to his face as other people came piling into the room.

"Rogers, Thor, how good of you to join us." The two men who entered were polar opposites in there appearance. The one addressed as 'Rogers', to Dick, looked clean cut and buff, not a hair out of place or a crease in his chequered button down shirt. The other, did he say Thor? As in Norse god? Regardless, he was dressed fully in silver and red amour, a great big Hammer in his hand. Dick's voice breaking with nerdy glee. "Mjolnir.." The raised eyebrows from the room's occupants were shuddered out by three women and a man with a bow piling into the room. A strawberry blonde stood slightly behind , the tallish brunette leaning into Hammer man's back while a shorter, curvier brunette hid by the taller brunette. The shortest of the three new women broke the uncomfortably silence.

"So we're summoning hot heroes from other dimensions now? Cool." The last thing Dick remembered was the Archer's nod before feeling a hard steel pistol whip knock him clean out.

Tony stood over the passed out and probably concussed young man. "Well that was just unneeded." Steve approached him from the left and stared down at Stark and Banner, who both shrugged, Stark beginning to repeat to the gang of heroes and girlfriends the story of his newly designed transdimensional gateway, which was in fact a upgraded microwave, and the effect it probably had on the young man who was probably using similar equipment in one of the unlimited number of time lines and universes that existed.

Everyone but Steve and Thor kept up with the conversation as they moved the young man to a secure yet pleasant looking room. Steve told Jarvis to inform Fury, the butler-AI obliged and another uncomfortable silence arrived as Steve gingerly went to remove the weapon's belt the youth was wearing. That was not a good idea.

The electrical shock that cruised through Steve would've knocked the average man out, but luckily it just ended in a severe ache in his arm while Tony's giggle echoed behind him. "Well that's not coming off." The next words caused everyone to turn and look at the young brunette at the back of the room.

"Can we keep him?"

Jane just rolled her eyes. "Darcy, we cannot keep the lost-being from another dimension."

Darcy replied with a huff and a comment which forced Tony to leave the room for his guffaw's. "You got to keep yours."

A/N: So, a very awkward first chapter for a set-up for the rest of my dimension hopping tale! I figured with Tony and Bruce having genius level brains and Dick being damn near close to it, they would be able to deduce what had happened quite quickly. Especially if they were already knee deep in data about it, plus, plot speed! Anyhow, which villain sent our flying Grayson cruising through worlds? Did he follow him through? Find our next time in…..Grayson's Grand Adventure!
