The 3DCG holds up in ways most TV anime doesn't even attempt. This isn't a nostalgia project that banks on you already knowing Gatchaman, Casshan, Tekkaman, and Polymar, it's a collision of four franchises that doesn't always land evenly, and newcomers will feel lost in the roster shuffle. But when the action sequences hit, the animation justifies itself completely, especially Casshan's fights. The real prize is Emi's arc, which gives the whole thing emotional weight beyond the spectacle. Watch this for what it does on screen, not what it assumes you already love.
Four legendary heroes from different eras suddenly find themselves transported into a world that shouldn't exist. Gatchaman, Casshan, Tekkaman, and Ippatsuman have each fought their own battles across decades, but now they're trapped in a digital realm where the rules of reality don't apply. A mysterious force pulls them together, and they must figure out why before this strange dimension collapses entirely. The catch: their powers work differently here. Their enemies are more dangerous. And none of them know if they can trust each other, since they've never actually met before. What unfolds is equal parts superhero spectacle and buddy comedy, as these hardened fighters learn to work as a team despite their wildly different fighting styles and personalities. The 3DCG animation brings an unexpected energy to the action sequences, making every collision feel weighty and consequential. Viewers who love classic tokusatsu energy mixed with character-driven storytelling will find something special here, along with anyone curious about how legacy characters function when forced out of their comfort zones.
