Captain and Optimus in Camelot

[The Vision]

As they approached the city gates, two humans raised their palms and motioned for the trio to stop.

"Halt! What brings you to Minas Tirith?" one of them said.

Optimus glanced at Scott, who knocked on his left breast with his fist once.

"I am Scott, son of Christopher, family of Summers-"

"We know who you are, X-Man," the guard interrupted, "I'm talking about the one in blue and... the... robot."

Optimus sighed. He was clearly not welcome in this city. He looked at Captain Rogers expectantly, beckoning him to answer.

"I'm Captain Rogers. This is my partner, Optimus Prime," Captain America replied, "Cycl- Scott here is taking us to Xavier."

"Well, your partner ain't exactly allowed in here. It's gonna have to wait outside."

"Listen, fella, I don't know what problem you folks have with robots," Rogers firmly said, "but Optimus is an ally of mine. I have no desire to leave him behind and I suspect he feels the same."

Optimus knelt in front of the guards, stooping his head. The guards flinched and raised their spears, scowling at him warily.

"I am not your enemy," he said calmly.

The guards glared at each other, then slowly let their spear hands relax.

"Fine," he said, "If Professor X trusts you, I guess you can come in."

Optimus rose to his feet and smiled at the guard. Scott passed between the guards. Captain Rogers followed suit. Optimus was about to step over them.

"BUT!"

"If you cause any trouble... We will have no mercy on you."

Optimus nodded, and rumbled, "Consider that a promise."

Optimus trudged away, ignoring the angry glares of the local villagers. The guard exchanged looks. One of them grumbled, "That Professor X is letting in robots now. Next thing you know, we'll have whitecaps patrolling the streets!"

Optimus heard them, but pretended that he didn't.
