Nihilus gets annihilated with ease. Frieza is way faster and stronger. And Force Drain isn't instant as I recall.
No it isn't. Waybig and I already explained the rules. But it seems kinda silly either way. Those who prefer either Starjun or Vadar want a specific version used and I'm no exception. Let's just say that Canon Vadar loses and EU Vadar wins. It's one sided either way.
I agree with this 100%.
