It came from the Toy Chest: Ghost of Grune the Destroyer

 

Former Thundercat, betrayed Jaga and was exiled from Thundera. Landed on Third Earthand wreaked havoc until his death. His tomb was sealed, but recently his seal was broken and Grune lives again as a ghost. Making a mace out of Thundranium... curiously, Grune is the only Thunderian immune to the life force sapping powers of Thundranium...

He challenged the Thundercats and kicked their assessment until Jaga came. Then it became a Ghost battle and Lion-O cheated to save his Obi-Wan...

That's Grune in a Nutshell. 

Ghost Grune Figure: Unofficial mascot of Lifealert.
Grune: I've fallen and I can't get up!

Articulation:

Loose joint city.

Legs flop like LeBron James. He is EXTREMELY limp-wristed. Can't hold his mace upright.

Head cannot turn. Not even going to try and pop it because Translucent plastic and Super7 sounds like a wasted money combination. His arms are also limited thanks to the pauldrons.

3.5

Despite leaning to the door and using mounting putty, Grune's mace flipped. I put it right side up, ut flipped to the other side and brought the figure down with him. I stood the figure up and tried again. Mace flipped again, but didn't fall this time. Fell after taking the pic.

Paint and sculpt: 

He's molded in Translucent plastic with color approximation dyed into it. There are a few painted accents (eyes, mouth, and teeth). Seems the interchangeable armor has been glued on this time. None of the sculpt issues were corrected from the past release.

4.5

Accessories:

Pair of open hands

Thundranium mace

Broken seal

Sword of omens.

Compared to the solid version, this is a rip-off... But since I skipped on the wave two figure; .This figure suits my purposes.

3.0

If Grune didn't have floppy legs, he'd be better...
Ghost Jaga will get an official review on this year's Advent Calendar.

Overall:

Grune gets a 3.67 as his final score. Honestly, I blame the reduced amount of accessories, the loose joints, and hindered articulation. The only reason to get this figure is to pair it up with the Ghost Jaga figure. But MY figure, specifically seems to act like a fucking drunk.
