Figure ID
njo391
Theme
Ninjago
Year Released
2018 (First appeared in January wave)
Rarity
Uncommon. While she appeared in a medium-priced set, she was exclusive to that set in this specific form with the purple Oni Mask of Hatred armor piece.
Head
White head with red eyes and orange facial markings. It features dual-sided printing with a laughing expression on one side and an angry expression on the other. It is topped with a black ponytail hairpiece.
Torso
Dark blue torso with olive green camouflage/tattered cloth printing. Details include silver chains, various metallic studs, and an orange belt segment. Back printing aligns with front armor straps. Arms are dark blue with black hands.
Legs
Black legs with dark blue and olive green printing. Details include chains, knee pads, and an orange loincloth/belt extension that flows down from the hip piece.
Accessories
The primary accessory in this image is the Oni Mask of Hatred (Purple), which is a unique molded piece that fits over the head. It features large silver spikes and a menacing face. In sets, she typically also carries a silver katana or a flail.
Color Scheme
A dark, gritty palette consisting of Dark Blue, Black, and Olive Green, with bright Orange accents and Metallic Silver printing for the chains/mask details.
Printing Details
High-quality pad printing on the head (dual-sided), torso (front and back), and legs (front). The alignment of the chains from the torso to the legs is a key detail for this figure.
Variants
There are three main versions of Ultra Violet: njo391 (Oni Mask version), njo431 (Master of the Mountain/Legacy version), and njo429 (standard version without the specialized mask armor).
Condition Notes
The ponytail hairpiece is prone to minor scuffing. The most common issue is 'clutch' wear on the Oni Mask side spikes and potential silver paint rubbing off the mask's teeth/spikes over time.
Estimated Value
Used: $8.00 - $12.00 | New: $15.00 - $20.00. The Oni Mask component accounts for about 40% of the figure's total value.
Price (New)
She appeared in set 70641 (Ninja Nightcrawler) which retailed for $39.99 USD.
Compatible Sets
70641 Ninja Nightcrawler (2018). Parts of this figure also appear in 70642 Killow vs. Samurai X if the mask is swapped.
Character Background
Ultra Violet is a high-ranking member of the Sons of Garmadon, a criminal biker gang. She is known for her manic personality and her obsession with the 'Oni Masks' which grant the wearer supernatural powers; the Mask of Hatred makes her skin nearly invulnerable.
Design Notes
The Oni Mask piece was a significant technical achievement for 2018, featuring a dual-molded style part that fits uniquely over a standard head while allowing a hairpiece to be attached on top.
Similar Minifigures
Mr. E (njo392), Killow (njo402), Harumi (njo403), and other Sons of Garmadon generals wearing different Oni Masks.
Collectibility
Moderate to High. Collectors of the Ninjago series seek her out to complete the trio of Oni Masks (Hatred, Deception, and Vengeance). Interest remains steady due to the popularity of the 'Sons of Garmadon' season.
History
Ultra Violet was introduced as a new antagonist in 2018. This figure marked the first time Ninjago utilized multiple specialized masks as a central 'collect-them-all' mechanic within a single wave of sets.
Interesting Facts
Despite her crazy appearance, her character was voiced by Maggie Blue O'Hara, who also voiced characters in the My Little Pony series. The mask she wears is designed to resemble a Japanese hannya mask.
Display Suggestions
Best displayed on a dark grey or black baseplate alongside the other two Oni Masks. Use a bright top-down light to catch the silver metallic printing on her chains.
Modification Potential
The Oni Mask is a popular part for MOC builders creating custom dark fantasy warriors or post-apocalyptic villains due to its aggressive, spiked design.
Overall Assessment
This is a standout figure from the 2018 Ninjago era. The specialized mask piece and detailed camouflage printing make it highly desirable for both Ninjago fans and general minifigure collectors. Rating: 8.5/10.
