An exercise in point crunching...

[Tom McCarthy]

Tyrannon the Conqueror was published back in Mystic Masters and the name remains part of Champions Universe, though little known and not a common everyday threat (like Dr. Destroyer or Takofanes).

I looked at Tyrannon to eyeball how suitable he is for 5th edition versus needing a complete writeup. I was only mildly surprised to note he costs about 6300 points less in 5th edition.

It's the whole Duplication change, it use to be that you had to pay for each one, now you just double for +5, when you have someone with THAT MANY high powered forms, it's going to save a bundle

But if you feel like you NEED those points, buy followers and add a thousand to his VPP, trust me your players will DRED seeing him

The duplification is a big change in cost between the two different versions. Of course you would probably have to bump Tyrannon's VPP up to 150-200 Active Points now to make him compatable with what we see in Dr. Destroyer and Takofane's sheets. Other than thoses two things though you can still use the old sheet without too much trouble.
