"Enjoy your deception, Vuel," Gerrard said as Volrath's features melted from the dead shapeshifter. "I'll count this one as practice."
Deadpool: Hey! Hey! Hey, Summers. Was that the big problem you needed help with? Because I just took care of it. (LIKE A BOSS.) (Huzzah.)
Cable: Wade, that wasn't-
Deadpool: Serious, roll credits. We're done here! (credits roll)
Cable: THAT WASN'T SINISTER, THAT WAS A CLONE!
It's a fair question. Why do they look like me? Doesn't it create the possibility that I am one? That Doom may, at any moment, be a mere machine? That I am not myself? Of course it does. That is how I wish it. I once let Arcade strike a match on me, just to maintain that confusion. Think, boy. If I am ever defeated, or dishonored - if I ever act in ways unworthy of myself...if I ever die...The word goes out: "It must have been a Doombot." And the reverse is true. My robots often fool my foes— I may be a robot now, speaking these words. How would you know? How would I?

"After a while, Edge got bored and decided to let Kane come and take his father back... only for it to end up being a ruse every single time. There was the flat-bed truck incident, then the impostor Paul trick, as well as the times he pretended to Zach-Gowen Paul down a flight of stairs, crush him, and run him over. All the while, fans at home were surely wondering whether Edge was using the same spare wheelchair and dummy every week, or if he had a stockpile of them that he took on the road with him."
You idiots! These are not them. You've captured their stunt doubles!

And how do we know you're even the real Winslow Schott? I've seen one of your robots before — no, two of them. One here in Gotham, the other on New Krypton. And that one had a part in my world's destruction. A small part, sure, but an important one. Your work is very well made. Impossible to tell apart from real, live human beings, even with my X-Ray vision. So please. Answer Ms. Grant's questions, or else another outburst like that will lead me to believe you're one of Schott's automatons... and I'll start probing to make sure you're real.
