A/N: Hey! This is my first fanfic so please be nice! It's going to be mostly BMWW with some other couples like GLHG and some others that I'll figure out in other chapters…But it's mostly going to be the JLU making fools of themselves and singing songs that suit them and stuff but anyways, moving on….

Disclaimer: As much as I want to I unfortunately don't own any tear of the characters sob they all sniff belong to DC Comics breaks down into tears

Also there will probably be references from episodes like "This Little Piggy", "Maid of Honor", and "Starcrossed". Others later, but I'll mention them at the beginning of the chapters.

Chapter 1: Doodles and a Party Notice

It was 9:00am Friday when Batman transported on to the watchtower. He planned to update some of the security systems in the monitor room, before heading to a very dull meeting at Wayne Industries. He walked purposefully in the direction of the monitor room. As he passed by the cafeteria he noticed that there was a lot of buzz for a Friday morning. Being the detective that he was, he decided to investigate.

The first thing he noticed was a small crowd standing by the bulletin board which usually displayed the monitor duty schedule, and other league duties. He approached the crowd that soon parted when they sensed the Dark Night's eyes on them.

"So, are you going to go?"

"Yeah it looks like fun." Were the first things Batman heard before glancing at the source of all the excitement.

"Diana, have you seen Batman today? He transported here ten minutes ago and he has yet to arrive to the monitor room", J'onn Jones asked through Diana's comm. link. Wonder Woman paused for a minute as she finished off the rest of the training simulation she had been working on.

"No, not yet J'onn, if you like I could go find him, and tell him that you're looking for him." Diana responded into her comm. link.

"Yes, thank-you, Diana" the Martian replied in his usual calm voice, before her comm. link went silent once more. Diana shut down the next simulation that had started, and left the training room.

Batman stood stiffly in the cafeteria, staring blankly at the notice on the wall, before reading it again for the third time.

'Come to the first ever Justice League Singing Super-Hero Palooza, tonight, here in the cafeteria!'

The notes seemed to have been written in a hurry, and most of the remaining space was taken up by poorly drawn pictures of stick people singing, and other random doodles with scribbled writing.

WHOOSH

Batman turned to glare at Flash who had just appeared beside him.

"Hey Bats! Coming to the party tonight?"

Batman responded to the question by giving the Flash another patented Bat-glare.

"Hehe…I know the person who came up with this idea must be a real genius, eh Batman?" the Flash continued, hoping that Batman would stop glaring at him like that.

"Flash…"

The speedster stood there ready to receive the dark threat that Batman was likely to throw at him.

"Next time you post an anonymous notice, try not to write 'Flash Rulez' in every spare space." Batman smirked that scary Bat-smirk and turned to walk away when he was met with the sight of a glistening Amazon. It would seem she was just working out, but even without showering after, she still looked like a goddess. Even Batman had to work at controlling his imagination, which was currently cooking up an interesting story of them doing certain things together, and her having the same appearance she had now (except with less clothes). 'Damn it, he shouldn't be thinking those thoughts', he reminded himself as he pushed Bruce Wayne, billionaire bachelor, to the back of his mind and concentrated on being Batman.

"Princess", he said acknowledging her presence with a slight nod, keeping his cool despite his previous thoughts.

"J'onn's been looking for you Batman. What's been taking so long?" she asked then peered behind him, reading the notice for herself.

"I didn't think you were the partying type Batman" 'Maybe not the Bat but I'm sure Bruce Wayne is' she thought to herself, while regarding Batman with amusement.

"Yup the Bats here is a real party animal" the Flash joked, finally speaking up. Diana laughed,

"You should come Batman" she said when she stopped laughing. She really did hope he would come.

"I'm not going" he said sternly before walking past her to head to his original destination, the monitor room.

Diana had to admit she was a bit disappointed that Batman wasn't going to come to the party, but then again he was the Batman. It was a shame; she had been hoping to hear him sing even though she doubted he'd do it in front of the whole league.

'He's sung in front of a crowd before there may still be a chance he'll do it' a small voice said inside her head.

'Yeah like he'd give up the Dark Knight persona even if he knew how much I wanted to see him sing this time, though I doubt he cares that much' her sensible side thought.

'He does care remember?' the hopeful side of her thought, and at that moment she recalled everything Zatanna had told her had happened while she was…indispose.

'He cares about you enough to risk his reputation' she pushed her hopeful thoughts aside and came back to reality. Noticing that Flash had already left, she decided to do the same, and go take a much needed shower.

"I don't know if it's going to work" Flash spoke into his comm. link, "He said he's not coming"

"Don't worry, there's still time to convince him. He has monitor duty in the afternoon" the voice replied through the comm. link.

"I don't know if Bats will be that easy to convince, but I know that Diana is coming, and Green Lantern, Hawkgirl, Black Canary, Green Arrow, Superman, and Supergirl are coming for sure, and I think Superman is even bringing Lois with him!" Flash said getting excited about the upcoming party.

"Good to know. Thank-you Flash." the voice said before his comm. link went silent.
