Alright. I'll go with that.
So what? Rider and Assassin realize that their losing to Archer and decide to go Super Saiyan?
Oh no, it applies to NPs too. EX NPs are unimaginably powerful. Gilgamesh's Ea (I think that's how it's spelled) is powerful enough to tear through dimensions. It was the wind that split the earth and sky after all.
More or less, yes. It's the ability to go beyond your normal limits for a short period of time.
Also note for Hud that not all EX's are created equally. An EX rank anti-unit NP is not going to be as powerful as an EX rank anti-fortress NP. Even though they're both EX rank, the anti-fortress is WAY more powerful. So if you had a clash between them, the anti-fortress would win out easily. Depending on the specific rules of the NPs of course. But like if it was a beaming contest like Balmung vs Clarent then the anti-fortress wins.
