What form did Luke use

how do you change your SN?

ok, we'll live the exile thing at that, bet they're gonna make some new forms just for the sake of KOTOR 3 anyway....buggers

I believe Luke practiced Ataru. Evidence; he was trained by Yoda (for the most part) who was a proficient master of Ataru, in his confrontations with Vader he does some flips (not quite as extreme as those in PT but you know), he also leaped quite high from the carbon freezing cahmber.

Every Jedi does jumps, and doing flips doesn't make you an Ataru practitioner. It's more than moves, it's an approach to fighting. Ataru is heavy on force-aided movements and acrobatics to overcome an enemy with sheer flurry. Shien/Djem So is a fighting style that is described exactly how Luke and Anakin fight, and by all accounts Luke -is- a Shien practitioner. It's not exactly up for debate.

Luke and Vader go for power-blows. Now, if Luke was making several fast attacks, blah blah blah, he'd be Ataru. Just because Yoda, Ataru Master, trained him, doesn't mean that Luke uses Ataru.

Just look at Dooku and Qui-Gon. Dooku mastered Makashi, Qui-Gon prefered Ataru.

I doubt Luke had any formal training. He probably wasn't a master of any form. But what I was trying to say is that it seems that he knows some Ataru which is logical because he was trained by Yoda. Other than that I can not say. It seems improbably he learned much from Obi-Wan in the ways of lightsaber combat.

Yoda taught him some, but Luke mainly taught himself. He was only on Dagobah for however long he was there in the movie, and that seemed like either a couple days or a week or so, and the span from ANH to ESB is three, and a year to ROTJ.

Like I said, just because Yoda trained him, doesn't mean that Luke uses Ataru, and I cited my Dooku-Jinn example.

Luke probably learned form five to a futher extent in the five years after ROTJ that Obi-wan continued to talk to him as a spirit. I said probably, so I don't have any proof, but it makes sense to me.

Thing was, Obi-Wan practiced Soresu, form three. Luke seemed to have self-taught himself.
