"Battle with the Bot", known as "Yuma vs. Cleaning Robot Obomi" in the Japanese version, is the twenty-first episode of the Yu-Gi-Oh! ZEXAL anime. It first aired in Japan on August 29, 2011 and in the United States on April 28, 2012.

As they head home from class, Yuma and his friends meet Lillybot whom they form a friendship with. However after the robot is reprogrammed to its former self, Yuma duels Lillybot in order to help her regain her memories.

Featured Duels

Yuma Tsukumo vs. Lillybot (first)

Duel is shown from an unspecified turn. Yuma controls no cards and has 2500 Life Points, while Lillybot controls "Junk Robot Teapot Kangaroo" (800/1200) and "Junk Robot Camelcycle" (800/1600), both in Attack Position and a Set card.

Lillybot's turn
Yuma's Life Points are damaged through unknown means (Yuma 2500 → 1900). Lillybot activates her face-down "Star Light, Star Bright", changing the Level of "Teapot Kangaroo" to that of "Camelcycle" as they have the same ATK. Lillybot overlays her two Level 4 monsters to Xyz Summon "Wind-Up Zenmaister" (1900/1500) in Attack Position. "Zenmaister" attacks directly (Yuma 1900 → 0).

Yuma Tsukumo and Bronk Stone vs. Lillybot

Duel is shown from an unspecified turn. Yuma and Bronk control no cards, while Lillybot controls a Set card.

Yuma's and Bronk's Life Points are damaged through unknown means (Yuma 0, Bronk 0).

Yuma Tsukumo vs. Lillybot (second)

Turn 1: Yuma
Yuma Normal Summons "Gagaga Magician" (1500/1000) and Sets a card.

Turn 2: Lillybot
Lillybot activates "Eco Spell - Reduce Waste", letting her banish two "Junk Robot" monsters from her Deck to add a "Junk Robot" monster from her Deck to her hand. She banishes "Junk Robot Cleanaga" and "Junk Robot Computerkong" and adds "Junk Robot Camelcycle". She Normal Summons it (800/1600) in Attack Position and activates "Eco Spell - Recycle", letting her Special Summon two banished "Junk Robot" monsters. She Summons "Cleanaga" (1200/800) and "Computerkong" (1000/1000). Lillybot overlays her three Level 4 EARTH Machine-Type monsters to Xyz Summon "Recycle Rhinobot" (2700/2000) in Attack Position. It attacks "Gagaga Magician", but Yuma activates his face-down "Half Unbreak", preventing its destruction by battle and halving the Battle Damage (Yuma 4000 → 3400).

Turn 3: Yuma
Yuma Normal Summons "Gagaga Girl" (1000/800) and equips it with "Wonder Wand", increasing its ATK by 500 ("Gagaga Girl"1000 → 1500). He activates the effect of "Gagaga Magician", changing its Level to 8 until the End Phase. He then activates "Gagaga Thunder", inflicting 300 damage to Lillybot for every Level of difference between his two "Gagaga" monsters (Lillybot 4000 → 2500). Yuma Sets a card.

Turn 4: Lillybot
Lillybot Normal Summons "Junk Robot Teapot Kangaroo" (800/1200). She activates the effect of "Recycle Rhinobot" three times, detaching the three Overlay Units to increase the ATK of a monster she controls by 500 for each detached ("Teapot Kangaroo" 800 → 1300 → 1800 → 2300). "Recycle Rhinobot" attacks "Gagaga Girl", but Yuma activates his face-down "Gagagaguard" as he controls two or more "Gagaga" monsters, preventing the destruction of "Gagaga" monsters by battle this turn (Yuma 3400 → 2200). "Teapot Kangaroo" attacks "Gagaga Magician" (Yuma 2200 → 1400). During the End Phase, the effect of "Recycle Rhinobot" activates as it has no Overlay Units, destroying the monster Lily controls with the lowest ATK and inflicting damage to both players equal to its original ATK. "Teapot Kangaroo" is destroyed (Lillybot 2500 → 1700, Yuma 1400 → 600).

Turn 5: Yuma
Yuma activates "Star Light, Star Bright", changing the Level of "Gagaga Girl" to that of "Gagaga Magician" as they respectively have 1000 ATK and 1000 DEF. He overlays his two Level 4 monsters to Xyz Summon "Number 39: Utopia" (2500/2000) in Attack Position. As "Gagaga Girl" was used in an Xyz Summon with another "Gagaga" monster, the ATK of a monster Lillybot controls is decreased to 0 via its effect ("Recycle Rhinobot" 2700 → 0). "Utopia" attacks and destroys "Recycle Rhinobot" (Lillybot 1700 → 0).
