10 Secrets Of The Batcave Explained

10. The Mechanical T-Rex

In terms of attention-grabbing trinkets, few things grab the attention more than an oversized animatronic dinosaur.

First appearing in 1949's Batman #35, the origin of the towering T-Rex can be traced to a run-in with an underhand fella by the name of Stephen Chase.

When industrialist Murray Wilson Hart creates the Dinosaur Island theme park brimming with mechanic dinos, he calls upon Batman and Robin to test out the accuracy of his work. The plan was for the Dynamic Duo to spend thirty-six hours in Dinosaur Island, without any weapons, and with the simple task of surviving.

Things go array for our heroes, of course, when career criminal Chase ends up taking control of Dinosaur Island and orders the animatronic beings to kill off the Caped Crusader and his trusty Boy Wonder.

As ever, Batman and Robin manage to overcome the odds, reprehend the bad guy, and save the day - and their reward was getting to take a hulking T-Rex back to the Batcave.

Few Batcave artefacts have been destroyed quite as much as the T-Rex over the decades, yet Alfred has always been there to pull off a quick rebuild and repair job whenever the need has arisen.
