The BB-120 Ultimate Beyta Stadium remains one of the most theatrical accessories Takara Tomy ever produced for the Metal Fight Beyblade line, and more than a decade after its release it is finally getting the collector attention it deserves. Launched on October 22, 2011, this stadium broke from the usual passive plastic bowl by integrating a motorized center disc, a hidden magnet system, and an exclusive Prototype Nemesis bey that was never sold on its own. The result was a home version of the arcade-style boss battles fans associated with the Bey Ta cabinet and the 4D anime arc known overseas as Metal Fury. Today, complete units with working electronics are becoming genuinely scarce, and prices reflect that scarcity, which makes accurate information essential before buying, selling, or restoring one. The sections ahead lay out the official specifications, including JAN code, physical dimensions, and battery requirements, then explain how the motorized boss mechanic actually behaves during a match and why the magnetic lock-in changes the rhythm of play compared with a standard BeyStadium. Authentication tips, the historical link to the original arcade cabinet, and a realistic look at current market value by condition are all covered in plain terms. Whether the aim is to anchor a Metal Fight display, recover a piece from childhood, or simply understand the design choices behind this unusual release, the breakdown below offers a clear reference grounded in verifiable detail.

Beyblade is not just a spinning top. It’s a hobby filled with strategy, customization, and the thrill of battle. Among the countless products released, one item stands out as a unique and unforgettable arena: Takara Tomy’s BB-120 Ultimate Beyta Stadium.
Released in 2011, this product gave fans the chance to enjoy a true “boss battle” experience at home, making it one of the most memorable items in Beyblade history.

Note: The name “Beyta” comes from the arcade machine “Bey Ta”. This stadium recreated the experience of challenging the ultimate enemy (Nemesis) at home.

System and How to Play (Practical Use)

• Motorized Center Disc: Spins left or right, with built-in magnet that locks the exclusive Bey into the center, creating a “boss battle” scenario.

• Defeat Prototype Nemesis: Players launch their own Beys with the goal of stopping or knocking out Nemesis. It is a challenge mode, not a standard head-to-head match.

• Two-Stage Height Adjustment (Difficulty Setting): Prototype Nemesis can be adjusted to two different heights (approx. 170 / 195). A higher setting makes it harder to defeat.

• Outer Tornado Ridge: Designed so Beys can speed up along the outer ridge before charging into the center for an attack.

[Exclusive Bey] Complete Guide to Prototype Nemesis

Source:Amazon

Released together with the BB-120 Ultimate Beyta Stadium in 2011, Prototype Nemesis is an exclusive Beyblade that could only be obtained through this set.
It was never sold separately, which makes it a rare collector’s item today.

Basic Information

• Name: Prototype Nemesis

• Release Date: October 22, 2011 (with BB-120)

• Exclusive to: BB-120 Ultimate Beyta Stadium

• Role in Anime: Modeled after the “prototype” of Nemesis, the ultimate villain Bey.

Features and Gimmicks

1. One-Piece Construction

   • Unlike regular Metal Fight Beyblades, which can be disassembled into Face, Energy Ring, Fusion Wheel, Track, and Bottom, Prototype Nemesis is a fixed one-piece model.

   • No customization or part swapping possible.

2. Magnetic Gimmick

   • A magnet is embedded in the bottom of the Bey.

   • This interacts with the motorized center disc magnet, keeping the Bey locked in the center.

   • This ensures it remains a “boss” waiting for the player’s attack.

3. Height Adjustment

   • Fixed with a triangular screw, allowing two adjustable heights.

   • Changes battle difficulty depending on the setting.

4. No Face Bolt

   • Unlike standard Beyblades, there is no Face Bolt, emphasizing its exclusive design.

Connection to the Anime

In Metal Fight Beyblade 4D, the forbidden Bey “Nemesis” appears as the final boss.
Prototype Nemesis is designed as the preliminary form leading to Diablo Nemesis, making it a piece that allows fans to relive the anime’s story.

Fan Reactions and Current Evaluation

• At release: highly talked about as “a chance to fight Nemesis at home.”

• Since it cannot be used in standard competitive battles, its value is more collectible than practical.

• Today: Many collectors seek Prototype Nemesis even more than the stadium itself, and it continues to command high demand in the secondary market.
