This is arguably the best Kaiju combat monster I've seen so far. There aren't enough chameleon monsters in the world and there sure as hell isn't enough symbiotic monsters in the world, and quite frankly this works on both plains. I can't understand why anyone wouldn't like this guy's design.
When you say "THAT'S F*KIN TEAMWORK", just make sure it doesn't sound... dodgy. Hehe. Don't get wrong I think they're awesome monsters. Also you forgot C in FUCKING (I know I know you left the g out as slang).
It's Freak the Mighty in Kaiju form! A Very interesting Symbiosis. Dozer is very sharp and spiky looking, and Bull has some impressive looking horns and spikes along his head. They are together quite impressive looking.
