"Brotherhood of the Fire Fist - Tiger King" and "Brotherhood of the Fire Fist - Lion Emperor" in the artwork of "Ultimate Fire Formation - Seito".
"Fire Formation" cards are focused around supporting Beast-Warrior-Type monsters. They are supported by the "Fire Fist" archetype, which consists of Beast-Warrior-Type monsters. Their connection is also shown in the artworks of the "Fire Formation" cards, since 2 different members of the "Fire Fist" archetype are shown in each.
So far, all of the continuous "Fire Formation" cards have two effects. They have one effect that can be used once while it is on the field (in the same way as a Normal Spell or Trap) and the same continuous effect that gives all of your face-up Beast-Warrior-Type monsters 100 ATK (Spells) or 300 ATK (Traps). Their effects can also be seen as mirroring the effects of other Spell and Trap Cards.
