Luke?

how strong is Luke in the following?
and what happens in between to make him stronger?
1. ANH Luke
2. ESB Luke
3. ROTJ Luke
4. NJO Luke
5. DN Luke
Oh and what does DN stand for?

I picked ROTS Luke- babies rule!

ESB Luke was the coolest. He faced down Vader without fear even though he knew he would most likely get defeated...like he did.

He had a definite badass factor going for him in ROTJ, I'm not going to lie.

Dn stands for Dark Nest, and ROTS Luke RULZ, atleast he doesnt have fanboys saying ZOMG LUKE IS TEH FORCE GOD...OMG OMG

ANH Luke whinged too much. But I Can't........But I Don't want too...........I gotta clean these droids up........But no-one likes me...etc..
