AntiMatter's Portal Hideout

Released in 2015 as part of the Ultra Agents theme, AntiMatter's Portal Hideout (70172-1) represented the climactic conclusion to the short-lived but inventive Lego original franchise. The set was designed to capture a high-stakes espionage aesthetic, featuring a villainous lair integrated with a sophisticated portal mechanism. It reflected Lego's mid-2010s experimentation with hybrid play, combining traditional building with a companion app that utilized augmented reality features to enhance the interactive experience.

The design emphasizes a jagged, dark color palette intended to evoke the chaotic nature of AntiMatter, the primary antagonist of the series. The construction focuses on modularity, allowing the portal to be dismantled or configured for various narrative scenarios. While the Ultra Agents line was ultimately replaced by the Nexo Knights theme, the design of this set remains noted by enthusiasts for its creative use of translucent elements and complex gear-based functions, standing as a hallmark of the late-era original intellectual property sets.
