The Sonic Shot is a Master Weapon used by Mega Man. It can revert the Roboticized Masters back to normal.
In SU#52, Tails modified Mega Man's Mega Buster to equal the properties of Sonic's Spin Dash. This weapon makes the target malfunction, reverting them back to normal. When used on a Roboticized Master, Mega Man acquires a special Master Weapon, unique to the bot that Sonic Shot was used on.
