Throwing Power - I made this list measuring the lowest damage that a character(doesn't matter who, see whole paragraph for details) needs for the crowd to cheer really loud from that character being thrown. Note: For Mewtwo's forward throw I measured both Pichu and Bowser when thrown, since the screaming percentage doesn't stay the same with it. Normally, THROWS(and ONLY throws) do not vary in screaming percentages. In other words, throwing Bowser won't make it take longer AT ALL then it would for the screaming percentage to occur than it would for Pichu, it'd be at the SAME EXACT DAMAGE. Please note, that this is ONLY for throws, and as for regular attacks WEIGHT DOES MATTER! FALLING SPEED NEVER EVER EVER AFFECTS SCREAMING PERCENTAGE, ONLY WEIGHT DOES). Try it with Bowser's up smash on a light fast-faller like Fox, and then on a heavy slow-faller like Samus, and even though Samus will be sent farther than Fox will, the SCREAMING PERCENTAGE won't occur for Samus until AFTER Fox's does. Anyway, here's the list of screaming percentages for each throw.
