Fonda Fontaine

Fonda Fontaine, known in Japan as Emi Ayukawa, is the head of the female Obelisk Blue dormitory at Duel Academy. In addition, she's the gym instructor as well as the school's head medic.

Mostly, Fonda is seen taking care of teachers and students whenever they are injured and doesn’t play a large role until the third year. When Duel Academy is transported into the desert, Fonda is transformed into one of Marcel's zombie slaves upon trying to protect the sick and injured Blair from the onslaught of zombified students trying to get into the infirmary. She duels against Jaden and ultimately loses. It is implied she turns back to normal like the rest of the people who were zombified after Duel Academy is returned to its proper place from an alternate dimension.

Deck
Fonda plays a Anti-Cure Deck which focuses on the reversal of Life Points recovery into Direct Damage through the ability of "Nurse Reficule the Fallen One". She uses cards such as "Dark Cure" and "Burning Algae" to forcefully increase her opponents' Life Points for this purpose, while protecting her main monster from being destroyed easily in battle with "Brutal Potion".
