Fans of tokusatsu transformation toys will probably get the idea straight away. GUTS Sparklence turns the Victory Hyper Gun concept into a pocket-sized simulator, letting you switch between character keys and trigger their matching transformation sequences and sounds. Ultraman Trigger gets most of the attention, with several forms to experiment with, while entrance clips, attacks, battle cries, and timer effects give the whole thing a little more personality than a simple transformation app.
The project comes from Bilibili creator xxxiranook, the same creator behind Orb Ring and other homemade Ultraman transformation simulators such as the Geed Riser and Ultra Z Riser. That shared style is noticeable: the focus is on recreating the small details fans remember from the shows rather than building a conventional mobile campaign. For anyone who enjoys collecting transformation devices and trying different combinations, it makes for a rather charming little side project.
