PUSH PUSH PUSH
Don't be afraid to push, because Zuvembie has Indomitable. Of course, this means Zuvembie needs to take some damage to get into those prized Exploit Weakness clicks. If you're carrying him around, Pulse Wave would be beneficial (to damage your opponents and give Zuvembie a click of damage). If you're playing Golden Age games, you can try putting Double Time on him.

But even if you can't get Zuvembie off his first click, he does have Shape Change to keep him alive. [2] damage won't do much in today's damage reduction world, but a little Outwit or Scent of Blood and you're good to go!

Edit: HeroClix fan "superfriend" has this to say: "It is my understanding that: Indominable grants the piece Willpower. Willpower is optional and can be turned off. So you should be able to turn off the willpower and push to the second click."

Superfriend is correct. Powers that do not have "non-optional" are considered optional. So you can indeed turn off Willpower for the purpose of taking Push Damage. Well done, Superfiend!
