"Kuriboh" (クリボー Kuribō) is an archetype used throughout the Yu-Gi-Oh! franchise. Most of its members are Level 1 monsters with 300 ATK and 200 DEF. The archetype also contains a sub-archetype: "Winged Kuriboh".
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!, Yugi Muto started with "Kuriboh", which he could discard to reduce battle damage that he would take from his opponent to 0 as well as use "Multiply" to protect him from battle. He uses "Clear Kuriboh" in Yu-Gi-Oh! The Dark Side of Dimensions. He can discard it to negate a damage-dealing monster effect or banish it from the Graveyard to potentially prevent a direct attack.
In Yu-Gi-Oh! GX, Jaden Yuki's Deck includes a "Winged Kuriboh" that he received from Yugi. His Kuriboh strategy focuses on Summoning "Winged Kuriboh LV10" with "Transcendent Wings" and Tributing it to wipe out the opponent's Attack Position monsters and inflict damage. His manga counterpart also has "Winged Kuriboh LV9", which restricts the use of Spell Cards. When his "Winged Kuriboh" is destroyed, all battle damage he takes that turn becomes 0.
In Yu-Gi-Oh! ZEXAL, Yuma Tsukumo obtains "Rainbow Kuriboh" during his time in Astral World, which was his father's card, and quickly forms a bond with it. Yuma would use its first effect to prevent his opponent from attacking him and would later activate its second effect of special summoning itself to protect himself from direct attacks.
In Yu-Gi-Oh! VRAINS, even though he does not use it in his Main Deck, Yusaku Fujiki used three copies of "Sphere Kuriboh" as shields during his infiltration of SOL Technologies' data bank. Linkuriboh would later cameo in an explanation on Link Monsters. Yusaku would later meet and obtain the "Linkuriboh" card after reuniting with Ai when the latter returned from the Cyberse World. Yusaku uses "Linkuriboh’s" effect lowering his opponent's ATK points to 0, thus making the attack useless and preventing Bohman’s attempts at victory.
"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 the "Kuriboh" monsters are Quick-Play Spell Cards, allowing them to function quickly in a themed Deck.
