"... and he was a good friend."

Every character has their part in this saga. Padme Amidala is just as important as any of the other major characters....ie. Anakin, Luke, Leia, Han, Chewie, Palpatine, etc.

Anakin and Luke, really, rate as the MOST important, as they are the centre of the story.

VEry. And then there is OB1, Padme, Leia, Palpy and Han. That about sums it up.

and all the rebels?

No.

and the stormtroopers?

No. Nor the Gungans or even, amazingly, the Ewoks.

Bothans? 😄

Hmmm where would we be without the "little guys"?????
It is sometimes the insignificant ones that FOIL the protagonists so well.

That was the point of the Ewoks.... and the ONLY point.

Wookies?

One view is that wookies are "big walking carpets"
But they also make great copilots and are great to have on your side in a fight.

Still now main character though.

True. I said it before and I'll say it again, the main characters are made so much brighter by being contrasted against lesser characters....so in a way the "little guy" is very important. (This seen only from a certain point of view)
