Change the ATK of an opponent's attacking monster to 0 by tributing this card.
In the anime, "Kuriboh" monsters are notable for being the Spirit partners of the main characters. A few episodes point out that "Kuriboh" monsters have special connections to the main characters who own various versions of this card.
In Yu-Gi-Oh! 5D's, "Kuribon", a monster similar in appearance to "Kuriboh" monsters, is used by Luna. It takes on a role as her Spirit Partner. Luna's Deck strategy focused on turning the Life Point gaining effect of "Kuribon" against her opponent with cards like "Oberon's Prank" and returning "Kuribon" to her hand to reduce Battle Damage to 0. In the manga, Yusei uses "Junkuriboh" in his Deck. He can discard it to negate any damage that would make his LP zero and destroy that card.
In Yu-Gi-Oh! ZEXAL, Yuma Tsukumo has "Kurivolt", another monster similar to members of the "Kuriboh" archetype, in his Deck. Yuma did not appear to have a spiritual partnership with it, but during his time in Astral World, Yuma obtains "Rainbow Kuriboh", which was his father's card, and quickly forms a bond with it. Kite Tenjo also has "Kuriphoton" in his Deck, which is similar to "Kuriboh" monsters in terms of effects, stats and appearance.
"Kuriboh" monsters are generally defensive in nature, and on their own, they tend to prevent Battle Damage from occurring to the user. However, some of their support cards allow them to rapidly turn the tables upon the opponent, such as the powerful "Winged Kuriboh LV10" and "Detonate". Most "Kuriboh" monsters have 200 DEF, so "Flamvell Poun" would be perfect for searching your Deck for them. So far, all non-monster support cards for "Kuriboh" monsters are Quick-Play Spell Cards allowing them to function quickly in a themed Deck.
