Perform all 25 X-Ray attacks in the game (excluding DLC characters) to get the "Need A Doctor" trophy. You can easily perform all 25 X-Ray attacks in Practice mode since you always have a full super meter. Each character has one X-Ray attack. They are activated by pressing L2 + R2. Note: You only need to use the standard character, and not any of the DLC characters, to get the trophy.
