This is my concept for the final boss of demo 6. 

I tried to write Zuka based off of my 7 deadly sins "theory", he represents envy. The mysterious figure gave Zuka a void star crown which made him go crazy and get locked in the lab to guard the Darkheart against his will as punishment.

(You unlock the door which has the Darkheart but it's not on the pedastal.)
(Zuka jumps down from the ceiling in front of you with the Darkheart)
     Zuka:
          "BACK OFF!"
          "Thanks for unlocking that door for me."
          "I've been craving this sword for years."
          "The DARKHEART's mine."
          "And those other swords... you don't deserve them."
          "I DESERVE them. I had EVERYTHING taken from me..."
          "..."
          "Everything..."
          "...Even Dignity."
(The Darkheart starts to corrupt Zuka physically)
(You and Zuka end up on those platforms on the tracks somehow I'm too lazy to write this)
     Zuka:
          "Feel the blade cursed with your nightmares."
          "For your DIGNITY has been lost."
(Battle Starts)
