1. Batman’s Trophy T-Rex
As it turns out, the Batcave houses more than just high-tech gadgets and Bat-vehicles, it’s also home to an impressive collection of LEGO Batman Movie Easter Eggs! Inside the Batcave we find reclaimed treasures from countless Bat adventures, like an over-sized penny and (above) animatronic T-Rex recovered from Dinosaur Island amusement park. The caped crusader battled this beast in Batman #35 (1946) and it was on display in the Batcave trophy area in Forever Evil #4 (2014). Dinosaur Island also appeared in Star-Spangled War Stories #90 (1960) as part of an ongoing War That Time Forgot series.
