After Tony got back from the Dr. Who Universe, Tony reappeared in his backyard, his heart still racing from the adrenaline rush of escaping the Doctor's TARDIS. The stolen sonic screwdriver sat snugly in his palm, its cool metallic surface a reminder of his escapade. He chuckled to himself, wondering what kind of chaos he'd left behind in the Doctor Who universe.
Then, a sound pierced the quiet evening air.
Waaaagh waaaagh waaaagh whining in the background
Tony's amusement faded instantly as a sound echoed from seemingly nowhere. His mind immediately recognized the sound.
'Oh, great. The Tardis.'
A familiar blue police box materialized right in the middle of his backyard, its arrival accompanied by the signature wheezing and groaning sound of the TARDIS engines.
The door of the police box swung open violently, and out stomped the Doctor, his coat flapping as he marched toward Tony with an expression of pure irritation. "You nicked my sonic screwdriver!" he accused, pointing an angry finger at Tony.
Tony grinned and held up the screwdriver. "Welcome to the Marvel Universe."
The Doctor paused mid-step, his face shifting from annoyance to sheer, unfiltered horror. His mouth opened, then closed as his brain struggled to process what he had just heard.
"The one where Thanos snaps his fingers and half the universe dies?" he whispered. "Where beings like the One Above All and Lady Death roam freely?" His voice dropped to a barely audible mutter. "Oh, no, no, no, no. Nope. Nope. This is bad. This is very, very bad."
A hand landed on the Doctor's shoulder, and Rose Tyler stepped out of the TARDIS, looking at him with confusion. "Doctor, what's wrong?"
The Doctor grabbed her shoulders, eyes wide with urgency. "Come dear Rose, we have some Daleks to slay! We need to go. Now."
Rose blinked. "Wait, since when?"
The Doctor shook his head. "Doesn't matter. We're leaving. NOW."
Tony crossed his arms, still grinning. "Oh, come on, Doc. Stay a while, enjoy the scenery. Maybe help me build a dimension-hopping Iron Man suit?"
The Doctor shot him a look of pure exasperation. "You're enjoying this far too much."
Tony twirled the sonic screwdriver in his fingers. "I really am."
The Doctor groaned, grabbed Rose's hand, and spun on his heel, marching back toward the TARDIS. "Nope, nope, nope. Not dealing with cosmic horror today."
Tony called after him, "Bye now! Have fun slaying Daleks!"
The Doctor shot him one last glare before slamming the TARDIS door shut. With another groaning wheeze, the police box vanished from existence, leaving Tony alone in his backyard once more.
He chuckled to himself, tossing the sonic screwdriver in the air before catching it. "Oh yeah," he muttered, looking up at the stars. "This is gonna be fun."
