Never saw the show Beastmaster. Didn't even know there was an Ultimate one.

While these sets were nothing amazing, this one is particularly lacklustre. The special leg print is nice, but doesn't set the minifigure apart in the same way as the knights with their transparent armour.
Even the other Ultimate monster sets had mor distinct minifgures from the normal version. Flama got recoloured from red to yellow.

Darn it, you beat me to it.

Interesting that the AntiMatter portal from 70170 was reused here.

There are nice pieces in it but the main attraction is definetly the minifigure.

Bring back the cowl you cowards!

Interesting that bundles of dynamite are somehow integral to the act of beastmastering.

Of all the Ultimate Lava Monsters, this one is probably the weakest. It comes with two orange glob guys (Globes? Globs? I can't remember) but that's about it. Still good for demon army building but not as cool as Lavarina's crazy spider legs or Flama's recolor. Magmar's Ultimate is a bit lame too I guess, but the regular Magmar set was so expensive compared to Beast Master and his build was a bit cooler.

I bought most of these ultimate packs (because I thought they were cool little packs full of interesting and new pieces and weapons), but I remember being underwhelmed by this guy.

When I looked at this set again I thought the portal might be a reissue of the portal print in 1382 Scary Laboratory and 4856 Doc Ock's Hideout, but it turns out that one is slightly different and that's white on trans purple whilst this is lavender on trans purple. It's from 70170 Ultracopter vs AntiMatter like @Noacat1 said correctly. It also appeared in 30604 Cosmic Boy.

Anyway, I agree that this set didn't have as much of a draw as the other Ultimate monsters did. That said, it's nice with a unique figure. That contraption on his back also frees his hands from needing to hold the two chains with his globlin pets (did they also become powered up here?). Fun fact: the assembly on his back goes all the way to the ground behind him.
Also: cowl!!!!

As for the dynamite power-up: Hey, as long as it works!

Still waiting for Ultimate Beauty Master.

Yes! You brought the Classic Space helmet back (albeit with a new, less fragile mold), now show Classic Castle the same love!

And yet nothing about his gear seems to suggest beasts, he's more demolitions master if anything
