This fragment is from one episode in which a Shaman made ilussions to
confuse and then attack the group. She tried with everyone. 
This is what she did to confuse Lyserg:

Lyserg: *stands with Morphin at the middle of a bridge 
             (HE'S WEARING A YUKATA!!!)* *hears 
             someone coming, turns to see, scary music starts*

Fake Marco: *appears*

Lyserg: WHAT?! You are....!!... an X-law...

Fake Marco: We must stop evil, and our main mission is to punish Hao

Lyserg: Do you too hold a grudge agains Hao?

Fake Marco: We will use our sword to vanish that dirty spiritual power

Lyserg: Who are you?.... explain it to me.

Fake Marco: We are the holy light... *walks backwards until dissapearing*

Lyserg: !! *runs to him ignoring Morphin who tried to stop him*
