ThunderCats has been a recurring target for premium figure lines over the past few years, and Mezco is the latest company to take a swing at it — bringing the franchise into its flagship One:12 Collective format for the first time. The company revealed a painted Lion-O prototype at San Diego Comic-Con 2026, shown at Mezco's booth under a straightforward Coming Soon card, with no price or release date attached yet.
What was on display, though, gives a solid read on the direction Mezco is taking the license. The prototype features a cloth tunic rather than sculpted-and-painted fabric texture, continuing the real-fabric approach that's become a signature of the One:12 Collective format across its DC, horror, and pop-culture lines. Lion-O's design leans into the classic cartoon-accurate look: a blue leotard with a distinctive chest cutout, deeper blue boots trimmed in white, and — critically for any Lion-O figure — the Sword of Omens included as a core accessory.
Mezco followed the Lion-O reveal shortly after with a Mumm-Ra tease, though that one is currently a digital concept image rather than a physical prototype, suggesting the ThunderCats line is planned as an ongoing wave rather than a single one-off release.
Confirmed at this point: Lion-O is the first physical prototype shown for the line, it uses One:12 Collective's real-fabric costuming approach, it includes the Sword of Omens as an accessory, and Mumm-Ra has been teased as a follow-up figure. Not yet confirmed: pricing, a release date, or how many figures the initial ThunderCats wave will include. Mezco's One:12 Collective line has generally priced in the $95-$140 range depending on accessory complexity and fabric detail, which gives a reasonable ballpark for what Lion-O might land at, but nothing is official yet.
ThunderCats has seen renewed collectible attention recently across multiple brands and scales, and Mezco entering the space with its real-fabric, high-articulation approach gives collectors a genuinely different presentation option than sculpted-plastic alternatives already on the market. The franchise's exaggerated character designs — Lion-O's proportions in particular — are also a reasonable fit for One:12 Collective's stylization, which tends to work best on characters with strong, readable silhouettes.
Given Mumm-Ra's digital tease already followed the Lion-O reveal, it's reasonable to expect Mezco will build this into a multi-figure wave similar to its approach with other franchises, rather than a standalone release. Pre-order timing typically follows a SDCC prototype reveal by a few months for Mezco's One:12 Collective line, based on the company's release pattern with other recent franchise additions.
Looking at how Mezco has handled other recent line launches gives a reasonable template for what to expect next. A prototype reveal at a major convention is typically followed by additional character teases (as already happened here with Mumm-Ra) over the following weeks, then a formal pre-order announcement with pricing several months out, and finally shipping roughly six to twelve months after the initial prototype reveal. That timeline isn't a guarantee, but it's consistent with how the company has rolled out other One:12 Collective sub-lines in recent years, and it's a reasonable expectation-setting framework for collectors deciding whether to wait for official details or start budgeting now.
Once Lion-O ships, One:12 Collective's fabric costuming benefits from the same dust and UV protection considerations as other real-fabric premium figures. The EVORETRO Acrylic Modular Case offers enough interior clearance for a 1/12 scale figure with an included weapon accessory like the Sword of Omens, while the EVORETRO 4-Step Acrylic Display Stand works well for a posed, single-figure spotlight display.
Mezco has not announced a release date or pre-order window as of this reveal; SDCC prototype reveals for the company's One:12 Collective line typically precede pre-orders by several months.
No official price has been announced. Mezco's One:12 Collective figures generally range from $95-$140 depending on accessory and fabric complexity, which gives a reasonable estimate range pending confirmation.
Mumm-Ra has been teased with a digital concept image following the Lion-O reveal, but no physical prototype or release details have been shown yet.
The prototype shown at SDCC 2026 uses a real cloth tunic, consistent with One:12 Collective's signature fabric-costuming approach across the line.
This is an early-stage reveal rather than a final product, but it's a strong first look — Mezco's fabric-and-articulation approach is a genuinely interesting fit for ThunderCats' character designs, and the Mumm-Ra tease suggests this will grow into a real ongoing line rather than a one-off. Worth watching for official pricing and release timing over the coming months.
