Obi Wan Kenobl vs. Anakin Skywalker (aka Darth Vader)

The very first time on Mustafar; the battle between the Jedi and the sith; were locking horns to the fight of death. Anakin has turned to the dark side his jealously and lust for power made him a cold and a very formidable foe. His anger is in full power when he saw his former mentor. Obi Wan told him it's not too late to change it to come back to the light. Anakin had enough of it, both Anakin and Obi Wan were caught on furious combat. Obi Wan is not only trying to save his former friend and student, but trying to stay alive since he is the only jedi left; so the fight has turned to save the last of the jedi. Throughout the fight; Anakin's dark powers made him more stronger; Obi Wan admitted that he failed Anakin, Obi Wan got the better advantage and won the fight. Anakin got transformed by his hatred on his former teacher, he is bound for revenge in round 2.

On the Death Star in the New Hope; the battle has reserved to Vader's advantage. No longer human; he became Darth Vader. The situation has been reversed since the first battle on Mustafar; when Obi Wan chopped him in the first battle; Vader send it back and chopped his former mentor, friend and brother to the force. Vader has been avenged from his revenge.
