Card Appearances:Relativity Field
- In episode 96, Dr. Eisenstein uses this card during his duel against Jaden Yuki. He activates this card on the first turn of the duel. After the effect of "Laplace the Fiend Mathematician" inflicts 1800 damage to Jaden (300 for each card on the field), the ATK of "Elemental HERO Neos" decreases by the amount of Life Points Jaden lost. After "Elemental HERO Bubbleman" (whose ATK was 1600 due to it being equipped with "Bubble Blaster") attacks directly via "Hero Dice", the ATK of "Brain Dragon" decreases by the amount of Life Points Eisenstein lost. On the last turn of the Duel, Jaden activates the effect of "Elemental HERO Glow Neos" to destroy this card and allow "Glow Neos" to attack directly this turn.
- In episode 120, this card is shown in a flashback Bastion Misawa has when he explains that after seeing Jaden Duel Eisenstein, he went on to study the field of quantum mechanics with Eisenstein.
