Any cards that reference “Adversary” are referring to the opposing faction, and may refer to a player, character, or card, depending on the context. When playing as an Autobot, for example, Decepticon players are your Adversaries, and Decepticon Bosses and Robots are Adversary cards you may battle. Likewise, you are considered an Adversary to an opposing faction when dealing with them. If a Decepticon player, Boss, or Encounter uses the term “Adversary,” it’s referring to you, the Autobot player, or your character in the Matrix.

This Encounter card specifies that the Adversary cannot be battled this turn. This applies to all players, regardless of who was Ambushed or whose turn it is.
