Sonic Battle Tips

Multiple Charged Attacks
When the upper meter, the green one, is filled, the next special (Shot, Power, Set) you use will KO the enemy as long as they didn't select "Block" for the type of move you're using.

However, when the meter is full, if you use an ultimate basic skill (meaning not Shot, Power, or Set), the added Special skill on the attack SHOULD KO the opponent (if they aren't blocking that type of special), but NOT drain the green meter, meaning this can be used multiple times. I use Ultimate Upper attack, which shoots a pink tornado off as Emerl flips backwards.
