The final bell for the day rang through the empty halls of Middleton High School, signaling every student to charge out of their class and make the halls considerably less empty. Kim Possible waded through the flood of teenagers until she located her locker, where Ron was waiting, as usual.

"Can you believe it, KP?" Ron asked, still thinking about what had happened during lunch. "We're going to hang with real live superheroes at our very own Bueno Nacho! Tell me you're not even a little bit excited."

Kim spun her locker combination into the lock. "Sure."

"Sure? That's it?"

"Well," she explained, "it isn't like we've never met superheroes before. They're just like us, Ron. The only difference is that four out of five have super powers and we don't."

"And secret identities," Ron added. "And cool costumes. And villains who remember their names."

"So what?" Kim asked, fishing out her math homework.

"So what?" Ron echoed, shocked. "So what? So everything! Do you know what it's like being a sidekick and getting zero respect for it?"

Kim shut her locker and picked up her backpack. "Um, I'm gonna say no."

"Exactly!" Ron exclaimed. "But I do! Nobody cares about the sidekicks. Nobody. Dr. Drakken still hasn't even figured out my name, and how long have we been fighting him? Years! But there is one sidekick that everybody's heard of: Robin the Boy Wonder."

"So you've been dying to meet him for some time then," Kim figured as the two began to walk away from her locker and down the hallway.

"Duh! He's the one sidekick anybody actually respects. He's the ultimate role model for the forgotten subordinate. And he's at Bueno Nacho! Our Bueno Nacho! With four other superheroes! How cool is that?"

He held open the door for her as the duo exited the main building of the school. Kim shrugged. "So not the drama, Ron. We're just exchanging information about our respective bad guys. It's not like this is a celebrity meet and greet."

"Okay," Ron sighed, "you go ahead and think that. But as for me, I cannot believe how awesome today is becoming!"

"I cannot believe how awesome today is becoming!" Beast Boy exclaimed inside of Bueno Nacho, looking at the menu above the counter. "Nacos? Nachos and tacos at the same time? Why has no one ever thought of this before? It's genius!"

"I'll say," Cyborg agreed, his mouth watering. "Man, we need to get one of these Bueno Nachos in Jump City. Seriously, who do I petition?"

The other three members of the team were seated in the largest booth. Raven was murmuring, "Azarath Metrion Zinthos" over and over, trying to meditate. Robin was looking out the window anxiously for Team Possible, still not totally comfortable with the meeting location. Starfire had her head in a magazine she had bought during their SmartyMart stop.

"Hm…oh! Friend Raven! Observe!" Starfire shook Raven out of her trance and pulled her behind the magazine. "This magical booklet claims that it knows the secret of which stereotype of the high school I would best to fit in with!"

"Find Out Your Crowd Quiz," Raven read the title, unimpressed. "What is this?" She looked at the cover. "Teen Glam magazine? You actually read this garbage?"

Starfire blushed, a little embarrassed. "It has many helpful hints about what articles of clothing are 'in', and tips about life in general. I read one once that claimed to know my IQ of embarrassment." She hastily shut the magazine and put it on the table. "I merely intended to keep up with the fads, Raven. Is this not what the normal teens do?"

"We're superheroes," Raven pointed out. "By definition we passed normal a long time ago."

Starfire looked down in disappointment. Ever since her arrival on earth, she had felt like she stuck out in a crowd. She was okay with being different, but she didn't like the feeling of not knowing what to say or do to fit in when she wanted to. She had been trying to pick up bits and pieces of earth teen culture wherever she could, but it never felt like it was working. Nobody looked at her like a monster the way they had when she first came to earth, but people still stared at her like she was some kind of orange-skinned, green-eyed freak. She was grateful that at least her teammates didn't mind her awkwardness too much. Still, it was hard to even go to the mall without someone being shocked at her choice of mustard as a beverage or laughing at her misunderstanding of common teen slang. Thinking about mustard reminded her of something.

"Robin?" she asked.

"Yes?" he turned his head away from the window.

She held out her hand to him. Inside were three miniature mustard packets from the condiment area next to the soda fountain. "Why is the mustard in such a small container? One cannot fit a straw into it, and it is too miniscule to make for a sizeable beverage."

Robin tried to explain it without embarrassing her again. "Um…well…that is…not everybody drinks mustard. Most people don't. A lot of people actually put it on top of other foods to make them taste better. You're supposed to squeeze the little packets of mustard onto something else, like a hot dog."

Fortunately, he did not need to explain hot dogs to her. Unfortunately, this was because she had made the entire team watch a documentary about hot dog ingredients once that still gave Beast Boy nightmares. Somehow, Raven's insistence that no human being would eat a bright green hot dog did not console him.

"Oh," Starfire replied, understanding better now. She looked at the mustard packets for a second, then ripped them all open and squeezed them into her cup. She grabbed a few more and continued the process until it was three-quarters full, then stuck in a bendy straw and slurped to her heart's content.

"I think I'm going to be sick," Raven muttered before shutting her eyes and continuing her mantra.

She was interrupted almost immediately by Beast Boy shouting, "Teen Titans, may I introduce to you, the Naco!" Cyborg shoved a tray of five Nacos onto the table and the two of them slid into the booth.

"Nacos?" Robin repeated, looking at the concoction questioningly. "A taco and nachos?"

"Genius, isn't it?" Cyborg grinned. "There's one for everybody, so chow down!" He grabbed one and began to munch on the cheesy mess.

"They're almost too beautiful to eat," Beast Boy said, wiping a tear from his eye before stuffing his mouth with his Naco.

Raven looked at her Naco, then at Beast Boy and Cyborg, disgusted. "Now I really am sick."

Robin picked up his Naco and took a bite, trying not to get gooey cheese all over his green gloves. "Mm…actually, they're not too bad. Starfire, you should try it."

Starfire was unsure of what to make of the mass of cheese, chips, and tortilla in front of her. Not wanting to disappoint Robin, or be the odd one out again, she picked it up and prepared to take a bite. Just before it reached her mouth, she stopped.

"Robin, you say that the mustard is often utilized as a condiment?"

"Yes," he said, swallowing a bite of Naco.

This was it. A perfect chance to show that she had been learning to follow earth culture. She grabbed five packets of mustard and squeezed them all over her Naco, then devoured the whole thing in two sloppy bites.

"That's it. I'm out of here," said Raven, getting up from her seat at the edge of the booth. "Star can have mine. I'm waiting for those two at the curb where I don't have to watch you all eat." She pushed open the door and stepped out.

Robin put down his Naco to check the time on his communicator. "It's three on the dot. They should be here any second." He looked around uneasily. There were only a few customers in the restaurant, but the afterschool crowd would be showing up any second. "As much as I appreciate these Nacos, I have to wonder about this location. Slade is serious business. There could be confidential information involved. This doesn't seem like a safe headquarters, or a headquarters at all."

"Chill, man," Cyborg suggested, now finished with eating. "This is just what you need to get your brain off of that Slade craze you slip into."

"Please, Robin," Starfire agreed, pausing the drowning of her second Naco in mustard to put her hand on his shoulder. "Cyborg is correct. You have great need of the relaxation. It is unhealthy for you to become so concerned about Slade."

"Well," Robin admitted, "I guess it is good to try new things sometimes." He slipped his arm around Starfire's waist and looked into her emerald green eyes, still finding it hard to believe that their adventure in Tokyo had been a whole month ago. It felt like just yesterday that he had been a stuttering idiot, trying to explain to Star that he didn't mind so much being "more the heroes", that he in fact wanted to be "more than heroes". He had honestly expected her to refuse him after all he had put her through, but by some miracle she had understood completely.

Starfire gave her boyfriend a quick squeeze and pulled out of his arm with a happy giggle. "I…um…have need of more mustard," she said, sliding out of the booth with a smile.

"Dude," Beast Boy said as soon as she was out of earshot, "get a room."

"More like get a date!" Cyborg interjected. "You two have been together for a whole month, and you still haven't taken Star out on a real date. It's getting ridiculous. Are even trying to be a good boyfriend?"

Robin stopped staring at Starfire being adorably confused at the condiment selection to glare at Cyborg. "I meant to ask her out after Tokyo, but then we heard Slade was back in Jump City. Since then, I've been a little busy. As soon as we stop him, I'll take her on the best date of her life."

"You'd better," Cy pointed his finger at the Boy Wonder as a warning just before Starfire returned with her hands full of more mustard. The drowning of the Naco recommenced.

The door of Bueno Nacho swung open as Kim Possible and Ron Stoppable entered the building. Behind them, Raven followed, her feet barely touching the ground and her hood hiding her face in shadow. The three of them found the others and slid into the booth.

"Hi," Kim said, addressing the superheroes. "So you're the Teen Titans, right?"

"Yes, we are," Robin replied. "We're from Jump City."

"So Batman moved?" Ron asked, trying to ignore the mustard-covered Naco sitting next to him that was practically sacrilege in his mind.

Robin glared at Ron. "I. Am. Not. With. Batman."

"Batman aside," Kim continued, "we need the down low on your Slade guy now that he's working with Drakken. Do you know what he's after?"

"We stopped him from stealing a test tube of highly experimental xenothium ore earlier today," Robin added. "Is there a way he can get any here?"

Kim thought for a moment. "I don't know, but I know who would. My dad's a rocket scientist. If he doesn't know the local xenothium sources, he probably knows someone who does. We'll have to ask him about it. So what else do you know about Slade?" Kim asked.

Robin looked around nervously. The restaurant was beginning to fill up with newly freed high schoolers munching on their Nacos. "Um…is this the right place to talk about it?"

Ron looked like he had been personally insulted. "Why wouldn't it be? Is this not the most perfect place ever? Please tell me you've tried the Naco."

"We all did," Cyborg told him, "and it was unbelievable."

"Yes, they were quite glorious!" Starfire smiled before filling her ninth stomach with the last bite of her mustard-covered Naco. Raven retreated further into her hood.

"The Nacos were great," Robin said, "but do you really think this is the right place to talk about super villains? Anyone could hear what we're saying."

This guy is so full of drama, Kim thought. "No one's listening to us," she assured him. "This is where I talk about my missions all the time. So is Slade into the whole 'take over the world' thing?"

"Usually he just tries to take over the city," Cyborg answered, now fully serious. "One time he succeeded, and it cost us a teammate. I wouldn't be surprised at all if he does want to take over the world, but just wants to start small and grow from there."

"So what's the deal with your blue guy?" Raven asked Kim.

"Dr. Drakken wants to take over the world," Kim explained. "He hasn't had much success yet, thanks to us. He's an evil genius and a criminal mastermind, and he's pretty handy at building doomsday devices. He's bad news, but the really evil one is his sidekick, Shego. She's a better fighter, and way more ruthless."

"You see," Ron pointed out to Robin. "Sidekicks can be cool. There is nothing wrong with…"

"Ron," Kim interrupted.

"Sorry, KP. Continue."

"As I was saying," Kim said, "it sounds like with Slade's drive for evil combining with Drakken's brain power and Shego's ruthlessness, we're up against a pretty huge threat. If we're going to take them down, we'll need to work together, as one team."

"Exactly what I was thinking," Robin chimed in. "What do you say, Titans?"

The other team members assented in their various ways.

"Ron?" Kim asked her sidekick.

"Are you kidding me? Of course I want to work with these guys!" Ron was elated. Now was his chance to work side by side with his sidekick role model and four other superheroes. Chances like this didn't happen every day.

Kim pulled out her Kimmunicator. "Great! I'll have Wade start locating Drakken, Slade, and Shego, and then we can head over to my house and see what my dad knows."

She turned around the blue device to that Wade and the Titans could see each other. Wade nearly spat out his soda. "Kim, who are these people?"

"We're the Teen Titans," Beast Boy said, puffing up with pride. "Superheroes extraordinaire."

"Drakken's anonymous contact is apparently their arch nemesis," Kim explained to the miniature computer genius. "I need you to start tracking Drakken, Shego, and somebody from Jump City named Slade. Also, have you ever heard of xenothium?"

"Hm…xenothium…" Wade pondered. "Nope, not ringing any bells. Wait! Isn't that the red stuff that nobody's supposed to touch outside of a lab?"

"Pretty much," Raven said.

"Find out everything you can about it," Kim commanded.

"On it!" Wade said, signing off to start his research.

Kim tucked her Kimmunicator back into her pocket. "Let's head over to my place and talk to my dad. If there's any xenothium in Middleton, he'll know about it."

The other six teens followed Kim out to her purple car. She opened the door and asked Cyborg, "Think you can follow us over?"

"In the T-Car?" the half-robot laughed. "You bet!" He clicked a button on a small remote. The T-Car beeped and pulled up next to him.

Kim and Ron stared at the suped-up automobile. The tweebs are going to be all over that, Kim thought. "Okay," she said as the Titans took their seats. "Then let's go!" She started her engine and pulled out of the parking lot, turning left toward home. The T-Car stayed right behind her all the way until she pulled into her own driveway.
