When performing Medi Bot, Tails walks up in front of his team and pulls out a small white dome-shaped robot, with a red ring on the bottom and a propeller on top, which is equipped with healing technology. Tails then deploys that robot by sending it to one of his team members so it can heal him/her. The chosen team member will then emit yellow crosses as Tails returns to his team position, and will continue to do so until Medi Bot wears off.
In gameplay, when performing Medi Bot, the player chooses one of the player's characters to be targeted by Medi Bot. The chosen character will then for the next three rounds of combat automatically regain a certain amount of Health Points and Power Points once each round. However, Medi Bot can only restore a character's Health Points and Power Points to their maximum capacity, so even if Medi Bot can restore an amount of Health Points and Power Points greater than the amount of Health Points and Power Points that a character is missing, the character will only regain enough Health Points and Power Points to reach their full capacity. The amount of Health Points and Power Points a character regains from Medi Bot can be seen by the numbers that appear over the character when Medi Bot takes effect (green number for Health Points and blue number for Power Points). The higher the level of Medi Bot is, the greater is the amount of Health Points and Power Points that it can restore each round.
When performing Medi Bot in gameplay, the player has to complete a series of real-time events by performing certain actions on the Touch Screen, in order to execute Medi Bot optimally.
The player has to touch and stay inside the outer circle that appears when it overlaps the inner circle and follow it in a small curve on the upper part of the screen from left to right.

Missing or not touching these circles correctly will result in Tails failing to perform Medi Bot.
