Author's Note: Erm, I know, I know it has been a long time since I updated this. Sorry? Like I said in my recent Iron Man one-shot, life happened and I have been betaing for quite a few people. I hope this makes up for it.

This is the sequel to the previous Iron and Kevlar one-shot 'Happy Birthday Wake Up Calls' but this time it is Tony's birthday. What's the worst that can happen right?

Wait! Before you go on! I'm going to do some advertising for my fellow Bats!Fan Second Star On the Left. You should go check out some of her Bats fics because she is a talented writer.

Disclaimer: In my absence I did not gain ownership of Iron Man or Batman. I still own nothing, dang it.

Anthony Stark was absolutely exhausted.

It was the Sunday after his birthday vacation and he had spent most of it partying as though it were his last, because as he had learned last year—you never know when it will be your last birthday. Unlike last year, though, he didn't make a complete ass of himself around Pepper due to the fact that this birthday he was able to go back to go home with her.

Going home with her is something he is still getting used to even though it has almost been a year since the Stark Expo disaster that ended with a kiss on that random rooftop.

Almost a cliché? Probably.

For his birthday they had traveled to one of his private estates located in the Bahamas where they spent a lot their time sunbathing. To Tony's disappointment Pepper refused to do so in the nude, even though he had offered to sunbath sans swimming trunks.

His disappointment had soon been forgotten when he was finally able to see the teal bikini she had decided to go out on the beach in.

Tony had even convinced Pepper to go to a few of the more exclusive nightclubs which led to the drinking, because Pepper refused to let him drink while on the beach. She had some argument about alcohol and the sun being a bad combination, but he doesn't honestly remember the conversation due to the fact he was too distracted by the teal bikini at the time.

Now after the long but glorious week, he is dragging himself through the door of his Malibu mansion trying to keep himself from collapsing on the leather couch. His skin was hot due to the scorching weather and the amount of sun he had gotten so the cool leather sounded divine.

As he made his way to the couch he notices a large pile of mail lying on the coffee table, and he lets out a long sigh.

Pepper will probably want to go through that in the morning.

One parcel in particular caught his eye though as he collapsed onto the couch. He picks the package up twisting it around trying to figure out what exactly it was because he was not expecting anything through the mail other than the random birthday cards from his social circle.

The return address was from Gotham City and Tony can't help but smirk lazily.

Wayne had sent him something, a present perhaps?

He quickly rids the package of the offending paper and studies the plain shipping box for a moment before opening tearing the tape that held it together.

He rips the lid open and he is disappointed to find that he cannot see exactly what he had received.

Damn wrapping paper.

Wait—damn pink birthday wrapping paper?

That arrogant asshole wrapped his birthday present in pink paper?

Tony's eyes narrow as he stares down at the rectangular shape in his hands. Its weight tells him that it's a book, but what could Wayne have sent him?

"Can that airhead even read?" Tony grumbles sarcastically to himself as he tears the offending pink paper off of the present and he was right to assume that it was a book. It was a plain book with a black cover which did not reveal the large book's title. The only significant feature on the cover was a yellow sticky note that had a short note on it in a very sloppy script. The note said:

Happy Birthday Stark!

Remember, payback is a bitch.

-Bruce

Tony frowns and asks aloud, "Payback for what?"

And then it hits him and his eyes grow wide. He had sent Wayne that Iron Man action figure for his birthday—

Tony turned the book so he could read the spine which read in golden script, Encyclopedia of Bats.

Tony lets out a laugh, "That mother fu—"

Yes, I didn't drop the F-Bomb on purpose because some people do not like a lot of cussing. I'm trying to be considerate of my more innocent readers.

I on the other hand can cuss like sailor, but I add a little more creativity and eloquence to my curse words.

Reviews inspire me to think of new plots for future Iron and Kevlar one-shots. (:
