Rainbow Dash has never felt this good. She goes to a ceremony celebrating the peace she has brought to Ponyville. But strong winds knock an telephone wire down, which electrocutes Rainbow Dash, while she's in her suit. Suddenly, this causes the suit to malfunction and go out of control.

Rainbow Dash apologizes for what happened and decides to help fix the destruction she's caused during the rampage. First, they bury the Iron Pony suit.
