Card Appearances:Underground Arachnid
- In episode 45, Roman Goodwin uses this card during his Ground Duel against Yusei Fudo. He Dark Synchro Summons this card by dark tuning "Dark Spider" with "Dark Tuner Spider Cocoon" (who was Level 7 due to Roman using the effect of "Dark Spider" on it). Roman then activates this card's second effect to equip Yusei's "Shield Wing" to this card. This card then attacks directly. Later "Road Warrior" attacks this card, but Roman destroys "Shield Wing" to prevent this card's destruction, however Roman still takes Battle Damage. Roman states that he intends to use this card's second effect to equip itself with "Road Warrior" during his next turn so that this card could attack directly. Yusei then activates the effect of "Road Warrior" to Special Summon "Turbo Booster". Yusei then activates the effect of "Turbo Booster" to Tribute itself and destroy this card.
- In the dub version, "Underground Arachnid"'s chest is covered.
- Its attack name is "Dark Net"(in TAG FORCE 4), while its effect name is "Twiner Thread".
