Who is the Magna Defender?  Just some guy with a major attitude problem.  We shall never understand his pain.  His son Zika was killed by Scorpius.  Magna Defender has only one goal: Revenge.  And heaven help whoever gets in his way.  He's also after the Lights of Orion, which he claims will help him destroy Scorpius.  Rumor has it that Magna Defender is actually Mike, Leo's older brother.  I disagree.  Magna Defender had fallen into a crevice in the Earth 3,000 years ago.  Mike fell into a crevice on Miranoi.....oh.....about three weeks ago (not counting the week in between episodes).  I don't think that Mike is 3,000 years old, do you?  I have a belief of my own.  I believe that Magna Defender's recent pain has something to do with the Lights of Orion.  But I could be wrong.   I think it's either the Lights, or his old age.  See that blaster in his hands?  He's about to blow your head off, so get out of his way!!
