we should be able to upgrade these characters to Galactic Legends:

Emperor Palpatine (because he's the main villain of the OT)
Jedi Knight Anakin Skywalker or General Skywalker(because he's the the Main character of the PT)
Jedi Knight Luke Skywalker (because he's the the Main character of the OT)
Jedi Knight Revan (because he's the the Main character of KOTOR)
ultimate's name suggested: "Heart of the Guardian"
Darth Revan (because he's the the Main character of KOTOR)
ultimate's name suggested: "Mantle of de Force"

you don't need more reasons, but obviously this is not going to happen.
