Biotron and Baron Karza Micronauts Japanese Inspired Super7 ReAction+ SDCC 2026 Exclusives Revealed

Super7 has pulled back the curtain on another pair of SDCC 2026 exclusives, and this time they’re reaching into the Micronauts universe with ReAction+ figures of Biotron and Baron Karza presented in gorgeous Japanese-inspired window box packaging. The Micronauts line has always occupied a fascinating space in the toy world, originally born from the Japanese Microman toyline by Takara before being reimagined for Western audiences by Mego in the late 1970s, so there’s a real full circle quality to seeing these characters return in packaging that pays homage to those Japanese roots. Super7 has been consistently strong with their presentation-focused exclusives, and the decision to go with window display boxes here feels like a deliberate nod to the era when imported Japanese toys were prized as much for their packaging as for the figures inside. Biotron, the towering robotic ally, and Baron Karza, the iconic magnetic villain who could swap limbs and combine with other figures, are two of the most recognizable characters in the Micronauts mythos, making them a natural pairing for a convention exclusive drop like this. Super7 announced the figures on Instagram, letting collectors know they can find these at booth #2343 during San Diego Comic-Con. For Micronauts fans who have been following what Super7 has been doing with the ReAction+ format, this is exactly the kind of release that hits the sweet spot between nostalgia and collectibility, and I love how the Japanese-inspired packaging adds a layer of historical context that ties these figures back to where the whole Micronauts story truly began. If you’re planning to be at SDCC this year, booth #2343 is one worth adding to the list.

Window Box Reveal

Both Baron Karza and Biotron are displayed in Japanese-inspired window box packaging, featuring silver card faces with bold red, white, and blue diagonal stripe patterns and Japanese katakana text. Baron Karza’s blackbody with red accent points contrasts nicely against Biotron’s white and red color scheme with its chrome head sculpt.

Biotron’s packaging gets a closer look here, with the chrome head sculpt sitting above a red chest plate that has a tinted cockpit window built into it. The figure’s predominantly white body is broken up by small mechanical details molded into the limbs and torso.

Baron Karza’s packaging gets the spotlight here, with the diagonal stripe pattern framing the window and Japanese katakana running beneath the character name. Red details on the chest and eyes punch through the figure’s deep black body, with silver bands wrapping the biceps and thighs.
