Sonic, Amy, and Shadow watched as the elevator in one of Tails' many workshops went down, down...Even further down? Down deeper than any of the three hedgehogs ever suspected.

Though it made sense, Sonic supposed. This particular workshop had been forged from an old Egg base from WAY back, back when Eggman went by Robotnik, and Fang the Sniper could be considered a common enemy. The local townsfolk had given the space to the two as a thanks, but Tails was the one who had really taken to it. It had been a while since Sonic had even THOUGHT of it, so he guessed he had merely forgotten how far down it truly went.

Finally, they reached the bottom, and were greeted by a reprogrammed Tails Doll, floating creepily as it spoke. "Do you wish for refreshment?"

"No thank you, M1. Just get project 9X2L fueled up and ready." Tails responded. "As you command, sir." The thing said, before floating away.

"Man, I really wish I could get that 'sir' thing programmed out. WAY too formal." The fox muttered, before activating a nearby panel and starting to punch in a code. "You mind telling us what all THIS is?" Amy asked, looking around at the various mechs and projects lying around the underground hanger before them.

"Back during the Eggman War, after Sonic...Disappeared, I reactivated this old bunker to build bigger and better stuff." Tails answered. "The Wispon prototypes, Badnik jammers, environmental detoxification equipment, stuff like that."

"It's an impressive armory, fox, but what does this have to do with our mission?" Shadow asked. "Well, think about it, Eggman War, Infinite was the big threat, but I couldn't ever get weapons ready for him. I either couldn't get data on the Phantom Ruby, or Knuckles needed me on other projects. I just didn't have the time to FINISH anything." Tails reached forward and pulled a giant lever. "But I've had a LOT of free time since!"

Slowly, a large object covered in a tarp was lowered from the ceiling, held up by various apparatuses and cables. Tails quickly flew over to grab the tarp, revealing a silver plane with massive thrusters, two round cockpits, and wings that spread out in a star-like formation. Its size was impressive, and its probable firepower showed even greater promise. Even Shadow cracked a smile at its intimidating visage.

"BEHOLD! The ultimate Anti-Infinite superweapon! The X-Tornado!" Tails shouted, waving his hands like a presenter. Sonic clapped in response. "Great job on the presentation, buddy! Lot of pizzazz!"

"Thank you, thank you!" Tails said, bowing in the air in mock humility. Amy and Shadow just rolled their eyes. "Can we PLEASE get to the part where we find Infinite and beat him up?" Amy shouted.

"Right! M2, activate the Ultra-Emerald radar!" Tails ordered another nearby Tails Doll, who activated a screen in a nearby corner. "Alright, I normally use this thing for Chaos Emeralds, but if I just adjust it with the archive of that data I got from Eggman..." The screen flashed with a hit. "There we go! Isn't even too far from here!"

"Then let's get movin'!" Sonic said, as he loaded up on the nearby wing. Amy escorted herself to the cockpit in the back. "OOH! Gunner's seat!"

"It's a three-seater if you want to get up there with Amy, Shadow!" Tails said as he loaded up into the front cockpit. "Pfft. If Sonic can ride on the wing, then so can I!" Shadow scoffed as he planted himself on the other wing. Tails just shrugged as he finished making flight preparations, the four soon zooming out to Infinite's location.
