5 Shocking Reasons Why The Infinity Nova THB-02A Thunderbolt 2.0 Is The Must-Have 1/100 Scale Model Kit Of 2025
The landscape of 1/100 scale model kits has undergone a seismic shift, and the epicenter is the highly anticipated release of the Infinity Nova THB-02A Thunderbolt 2.0. As of late December 2025, this kit from the innovative third-party manufacturer IN ERA+ (or ERA+) is not just a new entry; it's a definitive statement on build quality, design complexity, and sheer presence. It has captivated the mecha modeling community, offering a premium experience that many builders argue rivals—and in some ways surpasses—the established giants of the industry. This is the ultimate guide to the THB-02A Thunderbolt 2.0, detailing why it has become the most talked-about non-Gundam kit in recent memory.
The Thunderbolt 2.0 builds upon the foundation of its predecessor, the Thunderbolt 1.0, but introduces critical, game-changing refinements. This is not a simple re-release but a complete overhaul, primarily centered on a reinforced internal structure and new equipment. For collectors and builders seeking a complex, satisfying, and incredibly stable build, the THB-02A is the new benchmark for third-party mecha kits.
The Ultimate Guide to the THB-02A Thunderbolt 2.0's Core Specifications
The Infinity Nova THB-02A is the flagship model in IN ERA+'s "Infinity Nova" line, designed to push the boundaries of what a 1/100 scale plastic model kit can achieve. The kit is a blend of high-quality plastic and durable die-cast metal parts, resulting in a weighty, imposing final product.

1. The Game-Changing Alloy Skeleton and Joint Reinforcement
The single most significant feature of the Infinity Nova THB-02A Thunderbolt 2.0 is its full internal alloy skeleton, often referred to as a metal inner frame. This feature is a hallmark of premium third-party mecha kits and is the secret to the Thunderbolt's exceptional stability and imposing presence.
Why the Metal Frame Matters
Unlike standard plastic model kits, the THB-02A’s core structure is composed of die-cast metal parts. This provides several crucial advantages:
- Superior Stability: The metal frame gives the model significant heft and weight, preventing the dreaded "shelf sag" common in large, plastic-heavy kits. This is especially important for maintaining dynamic poses over time.
- Enhanced Durability: The alloy skeleton ensures that the joints, which bear the most stress, are incredibly solid. Reviewers often describe the metal frame as "solid AF."
- Tackling the 1.0 Flaw: The "2.0" designation is a direct response to feedback on the original Thunderbolt model. The new inner frame mold has been refined to address and reinforce the joint issues found in the first version, resulting in a much more secure and refined build experience.
2. Plastic Quality That Rivals Bandai's Best
For years, a common criticism of third-party model kits was the inconsistency in plastic quality, mold precision, and overall fit. IN ERA+ has completely shattered this stereotype with the Thunderbolt 2.0.
The plastic used in the Infinity Nova line is consistently praised by the community. Many builders on forums and review sites have stated that the plastic quality is "absolutely stunning," and "arguably on par with Bandai's recent new designs," drawing comparisons to premium kits like the Real Grade (RG) Hi-Nu Gundam.
The kit features immaculate surface details and high-precision molding. This attention to detail minimizes the need for extensive cleanup and putty work, allowing builders to focus on the joy of assembly. Furthermore, the kit often includes pre-painted parts and clear, high-quality runners, elevating the out-of-box presentation.
3. The Massive Manta Ray Assault Equipment
The THB-02A Thunderbolt 2.0 is most commonly sold as a bundle with the "Manta Ray" Assault Equipment, transforming the already impressive mecha into a behemoth of firepower. This equipment is where the kit truly earns its "firepower" description.
Key Features of the Manta Ray Set
- Increased Size: The Manta Ray parts, particularly the large shoulder and back units, increase the model's overall height to nearly 9.5 inches, giving it an overwhelming presence on any display shelf.
- Weapons Arsenal: The set includes a wide range of accessories and weapons, often featuring massive rifles, shields, and various close-combat implements.
- Dynamic Posing: Despite the added weight and complexity of the Manta Ray gear, the reinforced 2.0 metal frame ensures the model remains surprisingly posable and stable, allowing for dynamic, action-oriented displays.
4. Design Philosophy: Intricate Detail and Mechanical Depth
The design aesthetic of the Infinity Nova THB-02A Thunderbolt 2.0 is a masterclass in mechanical depth. It adheres to a philosophy of intricate detailing, making it a "busy" and visually dense model kit.
Every panel, vent, and joint is intricately molded, giving the mecha a hyper-detailed, realistic mechanical appearance. The armor pieces are designed with a high degree of separation and layering, which is a dream for painters and detailers. The focus on intricate mechanical details in the internal frame—even parts that will be covered by armor—demonstrates IN ERA+'s commitment to a premium, high-end collector experience.
The 2.0 version specifically features newly molded parts for the head and shoulder armor, further refining the overall silhouette and improving the aesthetic flow of the design. This continuous iteration shows the manufacturer’s dedication to perfecting their product line.
5. The Build Experience: A Joy for Intermediate to Expert Builders
Building the Thunderbolt 2.0 is widely described as a highly enjoyable and rewarding experience. The precision of the molds and the solid nature of the metal frame contribute to a smooth assembly process.
While the kit is complex and detailed, making it best suited for intermediate to expert builders, the quality control is excellent. The instructions are typically clear, though builders should be aware that instructions for many third-party kits may or may not include English translations, requiring reliance on visual diagrams.
The combination of a complex, detailed build, the satisfying weight of the die-cast parts, and the flawless fit of the plastic armor ensures that the Thunderbolt 2.0 offers a build process that is as impressive as the final display piece. It is a kit that truly provides value for its price point, setting a new standard for third-party mecha model excellence in the 1/100 scale.
