Figure ID
njo541 (Slayer) and njo542 (Destroyer)
Theme
Ninjago
Year Released
2019 - These debuted as the primary antagonist army for the Summer wave, coinciding with the 11th season of the Ninjago TV show.
Rarity
Common to Uncommon. While they appeared in multiple sets across the 2019 wave, the 'Destroyer' variant (with the translucent orange neck piece) was more prevalent in mid-to-large sized sets.
Head
The figures utilize a specialized dual-molded snake head piece. It features a solid reddish-brown top with translucent orange plastic on the underside and neck, representing molten lava/fire flowing through them. The 'Slayer' variant features a wider cobra-like hood, while the 'Destroyer' (center and back) has a more elongated, upright neck.
Torso
Tan base color with 'mummy' style wrap printing in dark brown and flame-like orange/yellow detailing. The arms are tan, and the hands are reddish-brown. The printing represents ancient Serpentine warriors resurrected with fire magic.
Legs
Tan legs with consistent mummy wrap printing that follows from the torso. The printing includes small instances of embers or glowing fire effects peeking through the wraps.
Accessories
The figures in the image are shown with copper-toned shoulder armor (specifically the 'Slayer' variant on the left and right). Normally, these would be equipped with trans-orange katanas or scimitars with flame pieces.
Color Scheme
Primary colors are Tan, Reddish Brown, and Trans-Neon Orange. The copper armor provides a metallic accent that matches the 'Fire Chapter' aesthetic.
Printing Details
High-quality pad printing with significant detail in the 'tattered' texture of the wraps. The alignment between torso and legs is typically excellent, a standard of the 2019 Ninjago era.
Variants
Standard variations include the Pyro Slayer (hooded head), Pyro Destroyer (long neck), Pyro Whipper (has a snake tail instead of legs), and Char (unique character with a small cape).
Condition Notes
The trans-orange plastic in the head is made of a different polycarbonate which is sturdy, but the copper shoulder armor is prone to 'stress marks' at the neck ring if removed frequently. Check for cracks in the tan arm sockets.
Estimated Value
Used: $3.00 - $6.00 USD per figure. New/Mint: $7.00 - $10.00 USD. Prices fluctuate based on the specific head variant.
Price (New)
These were part of sets ranging from $9.99 (70671 Lloyd's Journey) to $159.99 (70677 Land Bounty).
Compatible Sets
70672 Cole's Dirt Bike, 70674 Fire Fang, 70675 Katana 4x4, 70677 Land Bounty, 70678 Castle of the Forsaken Emperor.
Character Background
Part of the Aspheera's Serpentine army. Originally an ancient tribe of snakes, they were magically transformed into fire-undead warriors after Aspheera escaped her tomb to seek revenge against Wu.
Design Notes
The dual-molded head pieces are a highlight of modern Ninjago design, using the translucency to interact with light to look 'powered up.' They mark a shift from the rubbery heads of earlier Serpentine (2012) to rigid, detailed plastic.
Similar Minifigures
Hypnobrai (2012), Constrictai (2012), Vermillion Warriors (2017), and the Merlopia (Seabound) guards.
Collectibility
Moderate. They are popular for 'army building' (as seen in the provided image), but because they were produced in high volume, they remain affordable for new collectors.
History
These represent the third major 'Serpentine' revival in Ninjago history, following the original tribes and the stone/ghost iterations. They introduced the 'Forbidden Spinjitzu' scroll elements.
Interesting Facts
The 'trans-orange' neck sections are actually light-piped; if you place them under a direct light source, the eyes and neck appears to glow significantly brighter.
Display Suggestions
They look best in large groups on a desert-themed baseplate or alongside the 70674 Fire Fang (giant snake) set to create a battle diorama.
Modification Potential
Excellent for 'mummy' or 'undead' MOCs. The heads are highly sought after for fantasy-themed monsters or D&D style lizardfolk/yuan-ti customs.
Overall Assessment
A solid, visually striking army-builder. The combination of tan 'mummy' textures with the fiery translucency makes them some of the most unique foot-soldiers in the Ninjago franchise. High recommendation for fans of the 'Monsters' niche.
