Yes, but aren’t you saying that all other English cards have the 1 instead of the i? Stating yours is an error, or are you only mentioning the difference you noticed between japanese and english cards?
All English EXs from B/W and X/Y have the 1 instead of the ‘i’, which is why the Krookodiles printing is an error. I should note this isn’t a Krookodile EX I own(because I do not own one), we will have to wait until the boxes are actually released for confirmation.
I posted the Japanese version so people could compare them next to each other. But you can go back and look at any BW/XY EX card and see the the 1 is indeed not a 1 on the Krookodiles.
I don’t entirely think it is an I, I think they just messed up the font that they normally use. Ones, when they appear in the text of an effect, look exactly the same as the damage for Megaton Fang. Still an error. I’m just more inclined to say it is a font error than a typo.
