Funny thing to do with onslaught + 2 mii brawlers

[GS3K]

When two mii brawlers use onslaught at the same time and collide head on, their kicks will cancel out, and they will always hit each other on the final hit, which can result in a double KO if both are at high enough percents.

This happened to me playing firnedlies at our bi monthly worth a chuckle, not much else can be gained from it however.
