"Arc Fire!" Female Robin exclaimed, throwing fire right at Lucina who jumped back and slashed her several times, but she blocked every attack with her Levin sword and countered. "El Thunder!"

Lucina winced from the attack and then Female Robin slashed through Lucina, as she screamed in pain and fell to the ground in defeat. "The winner is, Robin!" Master Hand exclaimed.

"Pathetic..." She said as she walked away. "If you can't protect Chrom, you can't protect yourself." She said coldly to Lucina as her eyes widened at her harsh words as she walked out of the stage.

Later...

"Why is she so harsh?" Lucina wondered. "Ever since she came in, she's been so rude..."

"She's probably tough on you for a reason." Ike said. "She sees potential in you and wants you to get stronger."

"Then how come she flipped off Bowser, called Luigi mean names, threw Kirby's ice cream away and tied Wii Fit Trainer in a knot that required Ganondorf, Captain Falcon and Little Mac to get her back to normal?"

"I think she's just stressed." Roy said. "Stress does crazy things to you. She's probably letting off some steam."

"You call spilling soup in my lap 'letting off some steam'?" Marth looked at the brunette.

"Okay, maybe she's a prankster but worse than Toon Link." Roy said. "Who knows?"

"I've heard her call Mewtwo a mistake." Lucina said. "Maybe I need to go ask her..."

"If you want, I can come with you." Ike said.

"Us too." Marth chimed in.

"We might wanna invite Lucario too...just so he can protect us in case she decides to attack us." Roy said.

"Wimp." Marth muttered.

"I heard that!" Roy exclaimed.

"Thanks guys." Lucina smiled and then sighed. "I miss Robin...why did he have to go with my dad on an urgent mission?"

"Well, he needs his tactician..." Marth said. "Well, let's go see what's up."

"And bring Lucario...maybe even Greninja and Samus." Roy said as the three Fire Emblem characters glanced at Roy. "...She scares me."

"I knew it..." Marth chuckled as they walked to Female Robin's room while recruiting the Pokemon and bounty hunter.

Robin had her door locked and she was pacing around the room. "I didn't mean to say that to her...I didn't mean to do all those things. What is going on?!"

You have darkness in your heart. A voice said.

"Who said that?!"

You have darkness in your heart...that is why you are so mean to your friends.

"Show yourself!" She ordered, taking out her Levin Sword.

Instead of showing myself to you...maybe I can...help you embrace the darkness.

"Embrace the...darkness?" She wondered as she a dark aura surrounded her and then the door knocked.

"Hey, Robin? It's us...we want to talk to you." Ike said.

Destroy your friends...call out the Heartless and change this world. The voice ordered and then disappeared.

"Why don't you screw off?" Robin asked in a threatening tone.

"Well, we tried." Roy said as he walked away, but Samus grabbed his arm.

"We didn't even try at all." Samus said and glared at Roy. "Man up."

"I wonder..." Lucario closed his eyes, using his aura to go in Robin's room. "What in the..."

"Ninja?" Greninja wondered.

"I'm not detecting Robin's aura in the room, I'm detecting someone else's...and it's not friendly."

Ike unsheathed the Ragnell. "Alright, who are you and WHERE'S Robin?" He asked.

"Why don't you come in and find out?" She asked.

"Alright...you're going to regret it." He said and looked at his friends. "Stand back." He ordered as they nodded and took several steps back as he charged up Eruption and then unleashed it, making the door fly straight into Robin's room.

"A part of me is a little glad I didn't face him in the fourth tournament..." Roy said as the smoke cleared as they saw Robin standing near the bed. "You sure you saw someone else in here?"

"I'm positive. This aura I'm feeling..." Lucario looked at the woman. "I'm not trusting her."

"Uh...has Robin's eyes always been yellow?" Marth wondered.

"No..." Lucina said. "Who are you?"

"Well, I'm Robin of course." She smirked. "And now...time to do some redecorating." She then summoned Shadow Heartless.

"What are those things?" Roy asked.

"I think it's a new type of Shadow Bug." Ike said as he slashed them, but his sword went right through. "What?!"

The Shadows simply tackled Ike to the ground. "Get off of me!" He ordered as he tried to shake them off, but more kept coming.

"Ike!" Samus exclaimed and growled under her breath. "Why you..." She took out her Stun Gun and fired at Robin, but a Defender was summoned and blocked the bullet, and then the Shadows got off of Ike...he was gone.

"IKE!" Roy screamed. "WHAT HAVE YOU DONE TO HIM?!"

"He lost his heart to the darkness...and you will share the same fate!" She exclaimed as every Shadow in existence came and tackled them all to the ground, but Lucina kicked one away.

"You stop this right now, Robin!" Lucina ordered.

"Oh no..." Robin smirked. "I should've done this a long time ago." She said. "You can call me the Heartless Queen."

"You're not a queen, you're a tactician!"

"I never liked that title." She said. "Seize her!"

Lucina's eyes widened and quickly ran off as the horde of Shadows went after her. "SOMEONE HELP!" She screamed.

"What is it? What's wrong?" Fox asked as he was talking to Falco and Wolf.

"Ike, Marth, Roy, Samus, Greninja and Lucario have been killed!"

"What?!" Falco exclaimed and then saw the Shadow Heartless coming for them.

"Hmph..." Wolf said. "Those tiny things killed them? I'm not impressed." He said as they all fired at the Heartless, but they did jack squat. "What?!"

"It's no use! You have to retreat!" Lucina pleaded.

"Retreat is not in my vocabulary." Wolf said. "Let's go, you two." He said as they nodded and started attacking them, but they were overtaken.

"NO!" She screamed.

"Mama mia!" Mario exclaimed.

"Alright, we'll handle them!" Sonic exclaimed as he, Mario, Mega Man, Pac-Man and Snake got in battle positions and went straight for the Heartless, but sadly, like the others...they were overtaken and killed.

"MARIO!" Luigi and Peach screamed.

"There's no killing these guys?!" Pit exclaimed.

"There's only one thing we can do..." Mewtwo said. "We have to leave this mansion."

"But what about Robin?!" Lucina exclaimed.

"Forget about her." Mewtwo said. "That's not Robin anymore." He said as they all left the Smash mansion, but one by one, they were overtaken by the Heartless as there were only a few survivors that escaped, Lucina being one of them.

"Leave them be." Robin ordered. "They're useless anyways." She said. "If they step foot in this mansion...kill them." She ordered as the Heartless nodded. "Now...let us redecorate this mansion...and possibly this entire world."

The things that gives me ideas when i'm chatting with friends on Facebook... it's all their fault for asking why Female Robin is so heartless!
