Finally, the Arc League Championship begins! Duelists from Duel schools all around Paradise City gather, split into three classes - Youth, Junior and Senior.

Featured Duel: Frederick vs. Trevor

Duel is shown from an unspecified turn. Frederick controls "Doodle Beast - Stego" (1200/???) in Attack Position, 1 Set card and has 900 Life Points, while Trevor controls "Red Mask" (1600/???) in Attack Position and has 2200 Life Points.

Trevor's turn
"Red Mask" attacks "Stego", but Frederick activates his face-down "Doodlebook - Uh uh uh!", letting him negate an attack against a "Doodle" monster he controls.

Frederick's turn
Frederick draws "Doodle Beast - Tyranno". He Tributes "Stego" to Tribute Summon "Tyranno" (2400/1200), whose effect allows it be Tribute Summoned by Tributing a "Doodle Beast" monster. As it was successfully Tribute Summoned, Frederick activates its effect, letting him destroy a monster his opponent controls and increase the ATK of "Tyranno" by half the ATK of the destroyed monster until the End Phase. "Red Mask" is destroyed ("Tyranno" 2400 → 3200). "Tyranno" attacks directly (Trevor 2200 → 0).



Zuzu's skirt colored black instead of maroon.

  • In the English dub, Trevor refers to Frederick's monster as "Doodle Beast - Stego", but Frederick later refers it to as a "Sketch Beast", which is another valid translation.
  • In one scene, while some participants are talking about Yuya, Zuzu's skirt was mistakenly colored black.
