>>10908396the unreleased Gravity Rex comes to mind
sure it has some dumb hasbroisms, and the eye placement is a tad goofy, and the tail is almost plagiarized, but it's sleek and decently put together. and the idea is sound, a big ol horizontal T-rex with a big head is something they flat-out never had. only stompy kaiju and small-headed 45-degree-angle theropods.
