While playing the game, if you want to throw someone, get behind them and move to where you grab them from behind. Hold back and press B. This works really well with bosses. With normal enemies, it can take up to 50% of their health. I also have another hint. If you are picked up and thrown, and you dont want to fall and lose damage, while in the air, hold up and C and you should land normal just as if you jumped, and you wont have any damage dont to you. This is very helpful if you are playin a hard boss that throws you as one of his good moves.
