Wait, a discussion of cheap characters and no one mentioned Link?
Seriously, that spin attack does damn good damage and throws you almost half the stage! Plus he can spawn bombs, and use that annoying drop attack where he stabs DIRECTLY INTO YOUR HEAD.
I hate Link in SSBM.
<3 Roy. I agree, used as a button masher, he's cheap, but if taken the time with, Roy can be a powerhouse. Master the timing and throw distance of his Sword's Dance, because it is AWESOME.
