I was being facetious when I suggested Dillon, Hellspawn28, though I really wouldn't mind him with my suggested variant.
I don't think Reptile would talk like that. Here are some ideas for Predator vs Reptile intros.
1) Reptile drops from above, behind the Predator who turns around, and Reptile decloaks. The Predator cloaks, then decloaks, to which Reptile snarls in shock.
2) The Predator decloaks, so does Reptile, who snarls, and the Predator roars as if to say "Come on!"
3) The Predator, already decloaked, pops out it's wristblades. Reptile says "You're not the Predator, you're the prey" and the Predator replays "You're the prey" on it's recording device.
The Predator vs Kitana
Predator: "This will be easy" (from Jade's MK9 intro).
Kitana: What?! How dare you use my friend's voice!
Predator: "Too easy"
The Predator vs Scorpion
Predator: "Get over here!"
Scorpion screams in rage and throws his spear, which the Predator dodges.
Predator: "It's official, you suck"
Just one more: Predator vs Goro.
The Predator shows off a trophy to Goro. Goro grabs the trophy with one hand and crushes it to powder, and smirks at the Predator while flexing his arms. The Predator roars with fury and pops out it's wristblades.
