A Razorsaw's Edge

The new Age of Extinction Kre-O Microchanger combiners, Grimstone, Lazerbolt, Obsidian, and Volcanicon.

Gonna be honest here. While it’s easy to nail down Grimstone’s components as Dinobots (a theropod, an ankylosaur, an iguanodon, and a pterosaur), the others aren’t so easy. I mean, Lazerbolt’s guy Freezeout has Spinosaurus sails on his ARMS.

Maybe they’re supposed to be G1 Pretender style monsters?

But whew. New characters.
