If Glitch (EC) is attempted to be battled directly with a GameShark, a Lt. Surge will come up and send out this Pokémon, but will always freeze the game upon being told "sent out". If the player by luck manages to get Glitch EC sent out into battle by Lt. Surge, it is nicknamed 999999▓ and has a oversized HP bar. After it is sent out, the game freezes and the player can take no action. Glitch EC becomes ?/ when traded to Yellow Version.
If encountered in the wild using a GameShark, it will freeze the game and turn the music off until the game is reset. If Glitch EC by luck is successfully sent out by Lt. Surge, then the Pokémon that is sent out will be frozen and be renamed to 9999999999. While the Pokémon is being sent out, the screen will fill up with the character 9 in random locations.
After Glitch (EC)'s Pokédex entry has been viewed, a chaotic glitch song will occur.
