Incrementor (ナンバープラス Nanbā Purasu, lit. "Number Plus") is an ability that appears in Kingdom Hearts: Chain of Memories and its remake. This ability comes from the Shadow Heartless's Enemy Card. It increases all card values by one. Only Sora, Riku, and the Riku Replica have access to the Shadow Enemy Card, thus the only ones who can use the Incrementor ability.
