Round three: Fight!
Daultay Dofine
Dofine attempts to disorient Owen with political rhetoric, but Owen makes the sniveling Neimoidian eat his words. Literally.
I guess I'm your stepbrother. I had a feeling you might show up someday.
Dexter Jettster
Owen has to move fast to avoid a 4-armed full-nelson, but once Owen got Dexter reminiscing about his time smuggling spice from the moons of Iago, Owen was able to mash a salt shaker into the four-armed freaks face.
Where are you going?
Commander Cody
While the clone commander is busy switching sides in the war, the Lars family exhibits the tag-team move of the millennium. Beru sneaks up behind Cody and kneels behind him, while Owen shoves him over the top. Stuck on his back like an up-ended turtle, Owen makes short work of the manufactured fighter.
Take my speeder bike!
(The Owen quotations just aren't as cool as I'd hoped, but I got to work with what they give me.)
