Combo Plus (コンボプラス, Konbo Purasu?) is an ability introduced in Kingdom Hearts. It extends the user's ground attack combo by one additional attack. Equipping multiple Combo Plus abilities adds additional attacks to the combo.
In Kingdom Hearts Chain of Memories, Combo Plus is an enemy card effect that costs 15 CP to add to the deck and lasts for three reloads. Unlike most iterations of Combo Plus, this one increases both ground and air combos by one attack.
