We have the four legged Evil Spy with the pop out eyes, Mantenna New Eternia Masterverse in hand review is brought to you courtesy of Big Bad Toy Store! Continuing with the new figures of Wave 19, Mantenna is a character that fans have been clamoring for in the Masterverse line for a long time. It’s great that the evil horde is getting so much representation lately. New Eternia Mantenna made a splash at SDCC 2025 this year, and it’s creative engineering to make the Pop out eyes feature is ingenious and helps to make this new Masterverse figure a fan favorite! Masterverse Mantenna is a must have for any Evil Horde fan and for all Masterverse collectors! Mantenna New Eternia Masterverse is currently in stock and ready to ship at Big Bad Toy Store, so pick yours up today!

Let’s start out by checking out the stunning new packaging for Mantenna! The packaging for the New Eternia Masterverse Mantenna showcases a striking design on both the front and back. The front features the figure displayed in a window box with bold artwork of Mantenna firing a blast from his weapon, highlighting his bulging eyes and sinister fanged mouth. The back of the box shows a full illustration of the figure in action, wielding his staff in a rocky environment, along with close-up images that spotlight his pop-out eye feature and multiple head looks. It also includes a brief bio, describing him as the Evil Horde’s spy who scouts New Eternia for Castle Grayskull’s lost pieces.

The side panel artwork shows Mantenna blasting his weapon with his bulging eyes lit up, set against a cosmic background with Horde forces flying into battle. In the upper left, a Horde Command Ship hovers among a swarm of smaller attack crafts, adding to the sense of invasion and power. I love how the box art shows him mid-blast, firing his weapon alongside the the Horde with the Horde army flying above!

Let’s take a closer look at the figure because he is amazing. Mantenna creeps into the New Eternia Masterverse line with a grotesquely detailed update that stays true to his freakish roots while introducing new levels of realism. His four-legged sculpt is packed with insectoid textures and sharp armor detailing, highlighted by a bold red and blue color scheme that pops against his menacing snarl. The figure looks wild in this New Eternia redesign! Mantenna sports his classic four-legged stance but with heavily armored blue limbs and a more segmented, insectoid texture throughout. His oversized, bulging orange eyes and gaping mouth full of fangs give him a creepy energy that really pops under the glossy red head sculpt.

Here you can see all of Mantenna’s packout. He comes with a cool blaster that you can connect the eyeball pieces to. Plus he has eyeball extensions. The armor takes on a layered design, with metallic red and gold plates across his chest and abdomen, and his blaster is his freakin eyeball.

This side angle of Mantenna highlights the elongated, insect-like legs and clawed feet, which give the figure a strong sense of stability and creature-like posture. The raised shoulder armor and flared head fins further accentuate his alien silhouette, lending him a distinctly menacing, otherworldly presence.

Close ups of his legs, you can see his 4 legs with all their detail from front and back. Unlight most most Masterverse figures that come with double jointed knees, you will see that this figure has single joint knees

The neat thing about this Mantenna is the swappable eyeballs—each sculpted with eerie precision and a glossy, organic finish that makes them look unsettlingly lifelike. Combined with his Horde-branded chest armor and blast effect accessory, Mantenna looks ready to bug out and terrorize Eternia with unsettling flair. In order to swap out his eyeballs, you need to remove his faceplate. Before you try to remove his eyeballs, I highly recommend heating up his head with either a hair dryer or hot water. If you don’t heat this up, his eye balls are almost impossible to remove. But once you heat it up, the eyeballs pop out easily, then you can swap them out.

The yellow-orange orbs extending from the eye stalks gleam under the display lighting, emphasizing their translucent material and exaggerated shape. His extended blaster accessory, featuring a spiraling red energy effect and matching orb at the tip, reinforces the exaggerated visual language of the character. Mantenna looks fantastic in motion! Here Mantenna’s spindly four-legged stance really shines, showing off how poseable his limbs are while still keeping that bug-like balance. From the front, his wide, bulbous eyes and toothy maw look alive. From the back, those flexible eyestalks stretch outward with the translucent orange effects attached, creating a dynamic mid-attack pose that adds a ton of energy. The layered armor plates catch the light beautifully, especially the details across his chest and belt.

This close-up of the New Eternia Masterverse Mantenna figure highlights the character’s most iconic feature—his bulging, oversized eyeballs. The eyes are cast in translucent orange plastic with vivid red and yellow iris detailing, giving them an unsettlingly lifelike appearance that evokes the vintage fright factor. Protruding from deep-set sockets, the eyes are mounted on long, veiny blue stalks. Combined with his open-jawed expression and angular red faceplate, this sculpt captures the grotesque charm of Mantenna in a hyper-detailed modern update.

Mantenna shows off his wild, over-the-top personality in this kooky, creature-like pose that feels straight out of a Saturday morning cartoon.
