Rex

Rex from Toy Story 4.

Got him at Dollar Tree, they had a bunch of Toy Story toys, but this is the only one I wanted.

When BMC toys ran their Female Army Men Kickstarter they also ran a discount offer on some of their other stuff.  I got their Battle Mountain.

Seems like it would be a great Batcave to hold my Bat-Stuff.

Batman has a Bat-Museum in the Batcave and it includes a giant penny and a T-Rex.  He had an adventure were he faced a Tyrannosaurus Rex that turned out to be a mechanical device rather than a real dinosaur.  It ended up in his museum.  I think the fact that "Rex" is kinda toy like is perfect for that kind of display.
