A New Brawl?

Yes to a fight, no to T. rex or Spino or Giga. Well, maybe at the end T. rex saving the people and giving them time to get in the helicopter against two Yangchuanosaurus and killing them.

I don't think it'll be another majot fight in JW. The experience from JP3 is enough.

That would be cool Delta. Rex killing two Yangchus and saving the survivors

Let me think a bit here. Hmm,

the survivors, at the launch pad, hear at he rescue helicopter coming. They cheer, until a roar splits the air. A Yangchuanosaurus emerges, here to kill them. The yang runs at them and is about too kill someone when it is intercepted by a T. rex. The Tyrannosaur had headbutted its size, and pushes it to a tree. Another yang comes out and attack the T. rex. The Yangchuanosaurus double team the tyrannosaur, but the T. rex finally kills both of them, and the helicopter lands. Actually, after the heli takes off, the t rex kills the second yang, and then gives a mighty iconic roar. Credits. That would be awesome!
