This fight symbolizes the dark side of the Padawans heart (remember, these are Jedi Trials). The strength of your opponent is the strength of the dark side in your heart... so Galen has a lot to fear from this fight.
Your dark double will sometimes transform into Jedi robes. DO NOT attack him when he is wearing these, or you’ll damage yourself.
The first stage is pretty straight forward. He likes to use Repulse a lot, he’ll also use basic Lightsaber attacks and Lightning from time to time. He does have one attack where the screen gets a little blurry and all the controls are messed up for a short time. During this time, just run away. Other then that, use standard Sith Saber Smashes to beat him.
