Figure ID

njo634

Theme

Ninjago

Year Released

2021. This figure debuted during the 'The Island' wave which transitioned Ninjago into a more tribal, jungle-themed aesthetic.

Rarity

Common to Uncommon. While easily obtained in its original sets, he is specific to a short-lived sub-theme and season.

Head

Yellow head with black beard and eyebrows, angry expression. Features a unique dark brown hair piece with an integrated full beard and mustache (Part 73200).

Torso

Yellow torso with teal and brown tribal tattoo patterns, a bone/feather necklace charm, and a brown sash across the chest. Yellow arms and hands.

Legs

Sand Green legs with teal cloth printing and dark brown wrappings/sandals on the lower shins. The hip piece is Sand Green with teal sash knot printing.

Accessories

The figure is shown holding a bright green plant/vine stem piece. In official sets, he often carries a bone-themed spear or staff, and sometimes a shield.

Color Scheme

Primary colors are Yellow and Sand Green, with Teal and Dark Brown accents to fit the tropical island tribal theme.

Printing Details

High-quality pad printing on the torso front and back, as well as the legs. The tattoo-style swirls are very crisp, typical of modern Ninjago printing.

Variants

This is the standard version of Chief Mammatus. There are no significant regional variants, though other 'Keepers' in the theme share similar leg and torso styles.

Condition Notes

The high-volume hair/beard piece is prone to collecting dust in the crevices. Check for 'clutch power' on the hand as it holds the vine, and look for torso cracks at the sides.

Estimated Value

Used: $3.00 - $5.00 USD. New: $6.00 - $8.00 USD. This is a budget-friendly figure for most collectors.

Price (New)

Originally included in sets ranging from $20.00 to $70.00. Not sold individually as a CMF.

Compatible Sets

71747 The Keepers' Village, 71748 Catamaran Sea Battle, and 71740 Jay's Electro Mech.

Character Background

Chief Mammatus is the leader of the Keepers, a tribe living on 'The Island' who protect the Storm Amulet. They initially oppose the Ninja, believing they are there to steal the amulet.

Design Notes

The hair-and-beard combined mold is the standout design feature here, creating a seamless 'wildman' look that was relatively new for the time.

Similar Minifigures

Island Lloyd (njo633), Keeper of the Rumble (njo635), and PoulErik (njo651).

Collectibility

Medium. While he is a named leader character, the over-saturation of Ninjago figures keeps his price stable rather than rapidly appreciating.

History

Follows the tradition of Ninjago having 'elemental' or 'themed' antagonists each season, harkening back to the original 1994 Islanders theme.

Interesting Facts

Despite his fierce look, Mammatus is a misunderstood leader rather than a true villain. The mold for his hair was a favorite for custom 'Castaway' MOCs.

Display Suggestions

Best displayed with the Ninja in their 'Island' gear (teal/jungle camo) or within a jungle or beach-themed layout.

Modification Potential

Excellent for 'Wild Man' or 'Caveman' customs due to the unique beard-hair combo and the tatooed torso.

Overall Assessment

A solid 7/10 figure. It features great part usage and thematic cohesion, representing a unique era of Ninjago design.
