A new TV spot for Colin Trevorrow’s Jurassic World aired during Sunday night’s episode of The Walking Dead and it surprisingly shows much more than what we’ve previously seen. Of course, we all know that the plot hinges on a hybrid dinosaur, but now we know just how dangerous it is.

The 30-second spot features a couple of shots of the dangerous hybrid, which is named Indominus Rex. (Toy images posted at Jurassic World News show off what the full creature could look like in the final film.) Claire Dearing (Bryce Dallas Howard) tells Owen Grady (Chris Pratt) that they had created a sibling, but Indominus Rex ate it. Plus, the dinosaur is killing other dinosaurs for sport.

We’re guessing that at some point, Indominus Rex helps other dinosaurs break free from their cages, which explains why there’s a shot of a pterodactyl picking up a visitor. Claire, who is clearly in the John Hammond role in this movie, is left screaming, “RUN!” But it might be too late.

Universal’s Jurassic World, which Steven Spielberg executive produced, hits theaters on June 12. It is the first film in the franchise since 2001’s Jurassic Park III.
