The reason is that there are two versions of káiser the one with the Kaiser Nova is the one Banpresto created for srw F and F Final, the other one was the one Go Nagai adapted with the mazin káiser ovas, banpresto káiser have appeared in Srw F final, alpha saga and X, meanwhile Go Nagai Kaiser was in J, L, GC and 30. But there is only one káiser that have both final attacks and that appeared in Srw W. Káiser Infinitism apparently is based on with Go Nagai Kaiser
