Dimensional Location: The Gravity Falls Universe where Doctor Doom Killed Stanley Pines.

"The Avengers found Stanford's Hidden Laboratory! This is worse than Doctor Doom destroying everything! Now the Avengers will be investigating why Stanford Pines came to Gravity Falls and Old Man McGucket will end up telling them everything!" Bill Cipher was ranting in sudden frustration.

"The Time Baby didn't predict everything, I have a surprise coming!" The Other Bill Cipher proclaimed.

"Hopefully something powerful enough to keep the Avengers from attacking us." Bill Cipher Number One says worriedly.

"Have you ever heard of Lord Voldemort?" Bill Cipher Number Two asked.

"The Evil Wizard of Hogwarts?" Bill Cipher Number One asked back.

"I'm sending him here to fight the Avengers." Bill Cipher Number Two says smugly.

"That plan sounds doomed to instant failure." Bill Cipher Number One says back.

"Do you have another idea?" Bill Cipher Number Two asked curiously.

"Stanford Pines is still trying to get home, maybe we should tell the Red Skull more about Gravity Falls while we wait for his return." Bill Cipher Number One says back thoughtfully.


Tony Stark had been asking people about the Mystery Shack.

So far Stanford Pines sounded more Con Artist than Research Scientist.

"Tony, Shield Checked Stanford's Fingerprints and they don't match!" The Black Widow announced.

"Mister Mystery was a fake? How is that even possible?" Tony Stark asked bewilderedly.

"Read this." The Black Widow hands him the Background Check.

"Stanley Pines, Twin Brother of Stanford Pines." Tony Stank frowned at the Criminal Records.

"Doctor Doom killed the wrong one." The Black Widow summarized for him.

"Stanley Pines faked his own death, Stanford Pines might had gone into hiding when they switched places." Iron Man quickly decided.

"Stanford Pines had 30 Years to talk his Twin Brother into switching places with him and evade detection." Iron Man says thoughtfully.

"Nick Fury is still Investigating Stanford's Research." The Black Widow tells him.

"All Financial Records lead back to the Mystery Shack, either Stanford Pines went Hitchhiking or he never left Gravity Falls alive." Tony Stark speculated worriedly.
