Story Booster 01 (ST-01): the Field Supremacy leaders revealed
Bandai dropped the first wave of Story Booster 01 leader reveals on June 1, 2026, with the set itself slated for an August 21 release and Cross Force (FB-10) not even on shelves yet. This is unusually early for Fusion World marketing. The reason becomes obvious the moment you read the first ability line on any of the five leaders: when placed in the leader area, the leader plays a specific four cost extra field card from the deck. The set's tagline is Field Supremacy. Fields are back, and they are not optional.
Story Booster is a different product format than the main FB boosters that have run from Awakened Pulse (FB-01) through Cross Force (FB-10). What that format means for set size, rarity distribution, and reprint policy is still being shaped by these reveals. Here is what is on the table so far.
The Field Supremacy mechanic, briefly
Every Story Booster 01 leader revealed so far has the same opening line. When placed in the leader area, the leader plays a specific four cost extra field card from the deck. No search, no hard cast, no energy cost. The field is just on the table from turn zero.
This will look familiar to anyone who played the original Dragon Ball Super: Masters card game. In Masters, field-driven decks did a lot of work through cards that were just there from the start. Fusion World has not really committed to this pattern before, and it raises a real question: does field removal stay in the game, or does Bandai phase it out? Right now, almost nothing in Fusion World can clear a four cost field, and these fields are coming online instantly without spending resources. That math is one-sided.
The fields are also doing real work. Several of them are pieces that the deck cannot win without, which means there is no easy "tech the field" answer. If you are coming back to Fusion World after a break or starting fresh with Story Booster, expect field interaction to be a major topic of conversation as the set rolls out.
Three of those fields are already spoiled, one each for Son Goten, Majin Buu, and Majin Vegeta:
The five leaders
Son Goten (Red)
Auto-plays Fate Transcending Generations from the deck on placement. Standard swing-to-draw, with the wrinkle that hitting three or more key flips Goten to his awakened side. On the awakened side, at the end of your turn, if you used an extra with "Kamehameha" in its card name during the turn, you switch Fate Transcending Generations to active mode.
The field itself is the real story. Fate Transcending Generations is a four cost extra field with a permanent effect: during a battle, when you would pay the cost of an extra with "Kamehameha" in its name from your hand at a cost equal to or less than the key on your leader, you can switch the field to rest mode instead. In practice, your Kamehameha extras become free as long as the field is awake.
This breathes new life into Kamehameha cards from older sets. The one cost Kamehameha from Awakened Pulse is suddenly a free defensive boost. The God Kamehameha extra becomes free removal. This is the kind of design that rewards collectors with deeper card libraries, and it means Story Booster will pull demand on older singles too.
Vegito Blue (Blue, reprint)
A reprint of the Vegito Blue leader from New Adventure (FB05-025), with the interesting part being timing. Vegito support has been stacking from Dual Evolution (FB-09) through Cross Force (FB-10), and Story Booster 01 keeps adding to that pile. By August, the Vegito Blue deck will have three sets of overlapping support to draw from, on top of whatever Story Booster gives it directly. This is the deck most likely to be tournament viable on day one of ST-01.
Majin Buu, Pure Evil (Green)
Auto-plays Demonic Maze on placement. Three or more key flips to awakened. On the awakened side, you draw a card and Majin Buu gets 5,000 power for the battle.
The activate main is where the deck identity lives: once per turn, if you have five or fewer energy, the next evolve skill you activate on a card with "Majin" in its special traits at a cost of six or less is reduced by one. The cost reduction does not sound flashy, but it is the kind of effect that makes whole archetypes possible. Expect Buu evolutions across the chain (Buu Tank, Buu Han, Buu Galo, and the various Super Buu forms) to be the deck's spine.
Demonic Maze itself is a four cost extra field with an activate main: switch to rest, place a Majin battle card from your drop under the field, then add up to one card from your life to your hand. The "under the field" mechanic looks similar to what the red Trunks leader does (battle cards pull from under the field), and that comparison points toward how the deck will play out.
Broly (Yellow, reprint)
A reprint of the Broly leader from Saiyan's Pride (FB-08). No new support details revealed yet beyond the leader card itself and confirmation of the artwork, which looks fantastic. Yellow already got a tech bump in recent sets, so there is meaningful upside if Story Booster gives Broly more battle cards to work with. We will know more as Bandai keeps the reveals coming.
Majin Vegeta (Black, new)
The headline of the wave. Auto-plays Wicked Soul Discovered, and carries a restriction: you cannot play battle cards costing five or more for the rest of the game. This pushes the deck into a mid-range shape, which is something black has not really had before in Fusion World.
Three or more key flips Majin Vegeta to awakened. The awakened side has an activate battle on your turn, once per turn: for each key removed from this card by skills of cards with "Wicked Soul" in their special traits during the battle, this card gets 10,000 power for the turn. The pattern echoes the Spirit Bomb Goku and Namek Goku archetypes (scaling power through resource consumption), but the resource here is the leader's own key, which makes the math different.
Wicked Soul Discovered is the support field. Pay an energy, switch the field to rest, leader gains a key, draw two and discard two. Hand cycling on turn one. That is a deck that gets to its pieces fast.
Open questions
A few things to watch as more reveals roll out:
- What happens to field removal in Fusion World? If every Story Booster leader is going to play a four cost field for free on turn zero, the existing field-removal pattern feels obsolete. Bandai either has to ship answer cards in the set itself or accept that fields are a permanent fixture going forward.
- What does the Broly support actually look like? A reprint leader without new support is just an old leader. Yellow needs reveals to be evaluated honestly.
- What is Babidi doing? A Babidi extra was teased alongside the Majin Vegeta package. Early descriptions read as a cantrip, but that may change as more cards are spoiled.
How to track this in KiBinder
If you are planning ahead for Story Booster 01, here is what to set up now:
- Track ST-01 in KiBinder the moment it lands in the app. Pre-release tracking lets you watch what gets spoiled before launch.
- If you play Vegito Blue, your wishlist for the August release is already long. Set price alerts on the FB-09 and Cross Force Vegito support pieces if you do not have them yet, because demand is going to compound.
- If Goten Red lands as a strong deck, the older Kamehameha extras get a price bump. Watch the FB-01 Kamehameha and the God Kamehameha extra in particular.
- Plan your binder pages for ST-01 separately from the FB main sets. It is a different product format, and the rarity makeup may differ from what Cross Force taught you.
Bottom line
Field Supremacy as a Story Booster tagline is on the nose. Every leader so far is built around a free four cost field that is doing real work, and the deck identities follow from those fields more than from the leader cards on their own. Majin Vegeta is the most interesting design of the bunch (mid-range black is a real meta shift), and Vegito Blue is the most likely to be tournament viable on day one. Goten Red is the deck that rewards collectors with deeper old-set libraries.
Story Booster 01 releases August 21, 2026. Cross Force still drops June 12. KiBinder will track both as cards are added.
