You take the tiny cat in to meet Russell, hoping they might get to know one another and chill out a bit. "Russell," you begin, "I'd like to introduce you to...what did you say your name was?"
"Mr. Fluffums," Russell finishes for you with a low growl. "You fool," he says to you, "why have you brought him here?"
Mr. Fluffums lets out an evil laugh. "Yes, Russell Tiberius Automotive-Belly Leiderhosen Von Troutmask, it is I: you're eternal counterpart. I have been released from the Catfood Can of Sealing at last and come to reunite to our true form!" With that, Mr. Fluffums leaps from your grip, scratching your arms as he goes (that little git).
"No!" Russell shouts, but it's already to late; the two cats collide in a cloud of claws and fur. Slowly the new beast grows until it is cat-incarmate. Russell and Mr. Fluffums have fused to become the omnikitten! You are the first to witness the pure destructive power of the entity as it casually swats the planet into the sun.
