Yoko's effects reflect her abilities in the Outbreak games, particularly her backpack and Escape skills. Yoko's Level 1 effect allows the player to attach a card from their hand to her face-down. If the effect is used a second time, the card already attached can be placed in the player's hand. Her Level 2 effect makes her similar to Ada Wong (CH-043); the player can avoid her death by lowering her maximum Health by 20 (which would happen if she died anyway) so she doesn't have to skip her next two turns. Yoko has 70 Health.
