Teebo 80 8 202 150% 28.52%

I think the key is on the last level 8-8, you have to kill Shield Generator Droid MK4 first and then stun and kill Asajj Ventress so she can't use "Strike Fear" ability to dispel the Stealth. After that, it's easy because you can keep getting TM (turn meter) with basic attack. I tried three times but eventually I passed it. Good luck everyone :)
