First, you must let go your conscious self..



And by that I mean quit trying to land epic combos on this guy and just use this secret Jedi technique that's guaranteed to work 100%:

• If you're using a PlayStation controller, get in close and keep mashing the square, triangle, or circle button (whichever has the fastest combo for any given character) like your life depended on it.
  
• If you're using an Xbox controller, get in close and keep mashing the X, Y or B button (whichever has the fastest combo for any given character) like your life depended on it.
  
• If you're using some bootleg controller or a keyboard, just get in close and keep mashing whatever key corresponds with those basic attacks.

That's right, just keep slapping that baby like you'd slap your hog on a lonely night, and you're pretty much gonna stun lock this fool until the end of time. This means that you'll be able to knock him around until you slap the horns off his forehead - or at least until he either runs away or he finally bites the dust in the final room.

This applies for pretty much any character with a light saber, though I haven't tested any of the bonus ones that weren't in the original version, or any of the gimmick characters that use blasters. I can only guarantee that this will work for the original roster.
Also. some characters are faster and each one has different attack animations and timing for each of those basic attacks. You just need to figure out which one is the fastest and has the fewest animation frames before it loops (eg. for Obi-Wan it's the square/X attack, for Qui-Gon it's the triangle/Y attack, etc.) The general idea is to just spam him with whatever attack you have that's the fastest because trying to be fancy or skillful will only get you killed faster. So in other words, play it like you used to play Tekken against your brother.

If he manages to knock you back, just block for a few moments until he's open for an attack again, and the go back to spamming the basic attacks. You should also watch out for this red beam attack that he does the most towards the end of the last level, because he can easily knock you back with that and then run over and completely wreck you with a flurry of saber blows. So when you're getting close, just make sure you jump over the red beam until you're close enough to start spamming him.

This should actually work on most enemies and bosses in the game but to varying degrees of success, so I'd recommend playing the rest of the game normally. It's just more fun that way. IMO only Maul fight sucks balls and deserves to be cheesed like that.
