Ring Spark Field
Returning from Sonic CD, quote:
Strobing red/blue, with sparks crackling around him, Metal is certainly dangerous for anything and anyone in its way. You can activate the force with Custom Action 1, but only if you're on solid ground. Jumping, landing from a fall or spinning cancels the effects, otherwise auto-cancels in 5 seconds.Hobby Consolas i.23 p.21 said:Another powerful attack Metal Sonic has is Ring Spark Field, a radioactive force which also has it's disadvantages: the speed and energy of the robot decrease considerably.
Watch out, though - as the quote says, Metal Sonic slows down considerably when under effects. Use carefully.
