I really don't know how you could make this concept work. Improve it? Easy. Make the new head fold back into wings, or make it have a top and bottom jaw that can act independently so it can double-chomp things, or make it have some dumb volley-ball-style spike as its main method of attack. Sure. But it's so trash. The idea itself is so bad. They could have made it a quadrupedal supercroc. Could have even just increased the head size and made its jaws huge (still funny looking, but now with purpose), could have made it resemble american godzilla/zilla for that tyranitar parity, could have bulked it up into a hulking brute, could have made it a caveman again like the first post always says (which would have STILL been a callback to a prevo), could have made it long and serpentine to make it look elegant instead of feral, could have made it look feral and have intentional giant arms so it can run at you like some gorilla or something... so many different ideas would have worked FINE, but they went with this S H I T.
