Super Hero Front: Scramble Duel is a collectible card game published by Bandai in Japan and active from 1999 to 2000. The game features the tokusatsu superheroes produced by Toei, drawing primarily from the Kamen Rider and Super Sentai franchises. Characters throughout the card pool are rendered in SD (super deformed) chibi art style rather than realistic illustration. The game system was derived directly from Super Robot Wars: Scramble Gather, Bandai's earlier mecha CCG, and adapted that framework for live-action hero properties. As a Carddass-family product, cards were distributed both through retail booster packs and Bandai's vending machine network. The game occupied a brief window in Bandai's late 1990s card game output and is now out of print. Sealed product and individual cards surface occasionally in the Japanese secondary market among tokusatsu collectors.
