Would like an IRL Tyrannosaurus seeing Rexy in it's environment, be like if a man sees an anime girl walking around in real life lol

It's actually refreshing to see Rexy get a happy ending in one of these scenarios instead of always subjecting her to harsh living conditions that she has to fight for her life in 24/7. Hope she and the male Rex grow old together <3

The combination between rexy and irl Rex is actually terrifying

POV The Overseer:<br><br>hadrosaurs deserve more respect to their names as some people treat them like overgrown cows. afterward he literally describes every danger an "oversized cow" could cause. COWS need more respect to their names.

Rexy would also have a weirdly long lifespan for a "T. Rex" she's pretty resilient even as a grandma.

Damnnnn I didn’t know irl T.rex had game like that, lowkey pulled a baddie 🥶💀🙏

@JohnCena8351 · 1 year ago
It would actually be interesting to see what role she would take in the environment. <br>No doubt Rexy can and will hunt even adult Triceratops (as seen in the 2010 telltale game), but given her speed, she's kinda like a mix between the bulky and powerful adults and the slender and speedy juvenile and sub adult Rexes.<br>So she could kinda become some sort of "generalist" T.rex, either hunting large or small and quick prey depending on what's available.

I kept wondering if Rexy's ability to roar would've been brought up<br>Cause it would be immensely useful<br>History has shown us loud noises can make even the biggest animal suddenly very apprehensive
