This creature is sort of in an odd place in that it's never appeared in any media for the franchise it was made for outside of some toys. But somebody on the Discord requested it and I thought some cool things could be done with it, so I wanted to try statting it out. Step into the Jurassic Park and discover - the ultimasaurus!
Much of this creature was taking abilities from other dinosaurs and mixing them into this beautiful monstrosity. I originally gave it powerful bite, but that ended up being too much damage for it. While I'm fine with it having higher than average offenses, since it lacks any real defenses, that ended up being too much. Leaping charge is meant to give it a way to get into combat quicker before it gets too locked down. I ended rend after deciding that it should be able to do so with its talons.
Pathfinder 1e Version:
This was fun to design for 2e. In particular, I really like the Fling into Fangs attack, probably because its an original move. The rest are largely borrowed from other creatures, such as the leaping charge. I was considering giving it some more traits from the 2e triceratops such as the frill defense, but I can't really imagine the ultimasaurus to readily allow a rider. Trample also didn't feel like a proper fit for him, so I went with powerful charge instead.

ENCOUNTERS
Saurian Slaughter: An attempt by a wizard to build a zoo of extraordinary and magical creatures goes awry when greedy workers attempt to steal the exotic creatures but inadvertently release them. As the beasts run amok, the heroes are brought in to round up the creatures and put them down completely if necessary. There are also trapped workers that the heroes must save but one of the greatest threats stomping through the zoo is an ultimasaurus, a savage beast that seems outright sadistic in its killing and takes an interest in stalking the heroes.
Prime-Evil: An ultimasaurus has been menacing a frontier town at the edge of a jungle, massacring livestock and eating those who venture into the woods. The town approaches the heroes with promise of gold if they slay the beast, but they must track it to its lair. Navigating the dense jungle is no easy task and creatures left hungry by the ultimasaurus’s appetite may attack the heroes, but the real danger comes when the heroes discover that the ultimasaurus isn’t the only threat. A druid has been siccing the dinosaur upon the town with the intent of driving them off and slaughtering them if necessary to reclaim the land.
