Zim and Gaz made their touchdown on Mars. The ship's door opened with steps leading down to the lush greenery they left behind while traveling to Venus. Zim stepped down.

"So," Zim said, "I think that went smoothly." He emphasized the last word to effectively remind himself of how well it went with the Venusian queen.

"I'll say," Gaz said, distracted by her GS-5, "She didn't try to bite your large head off this time." Just as she got through saying this, another large ship, covered in brightly colored pastels, with the picture of the US flag, the NASA insignia, and several rainbow drawings, crash landed ten feet from them. The door slid open quickly to reveal a half-beaten Keef.

"Zim," Keef said excitedly, crawling up from the strangled wreckage, slowly standing to his feet,

"Hey, buddy. How ya doin? You didn't answer my emails! Why not?" He wasn't pausing; this was giving Zim and Gaz a headache. "Oh, but it doesn't matter. I came to see you in person! So now we can go fishing, garbage picking, whaling, and playing chess all at the same time! Isn't that what best buddies do!? Doesn't that sound fun, Zim!?"

"I remember you," Gaz said, turning her head to the side in both remembrance and pain of his screeching, "You're the one that stalked my husband and brother. But I think I speak for him in saying he's a very busy man and doesn't have time for that right now." Zim already had his finger up to retort Keef's comment, but he was content with what Gaz was saying.

Keef frowned for a moment but then regained his smile.

"But I'm sure he can make some time for his bestest buddy," Keef said, grinning and shutting his eyes in a naked, naive joy, "because I love him, and he loves me!"

"But you're mistaken," Gaz said, "He doesn't love you, because he loves me. So, beat it."

"But that's impossible," Keef said, eye twitching and face cracking, "He loves me more, and I'm prepared to defend that."

"Then bring it," Gaz said, "Put up or shut up. Either way, I want you to go back to Earth. You're bugging us."

"I'll show you," Keef said, smile returning to his face, "let us duel."

With that, they both lunged for one another, colliding in the air. Gas swung her foot, which Keef blocked. Keef threw a punch, which Gaz pushed up into the air and returned with one of her own into his gut. Keef let out a yelp without lowering his smile while coming down on her with an elbow smash, which sent them both to the ground.

For twenty minutes, the battle between Keef and Gaz continued on without a victor, leaving a bewildered Zim to watch. Keef and Gaz paused for a moment, limping on the ground and staring into each other's eyes with hostility, Keef still grinning widely. They both knew this was futile; there could be no victor between them at this rate. Thus, they decided to settle it in a Soulcalibur 12 tournament. The three of them walked into the ship to set up the game system.
