User blog comment:Teridax122/Regarding Recurring Kaiju/@comment-5895493-20150808084854

I think important Kaiju and Aliens like Guruman, and Rei's Battlenizer Kaiju that have appeared more than a couple of times, and are recurring and important characters to a series, should be included. Others, like the Pegassa Aliens you stated a few comments down, should not be included. But that's just my opinion on the matter.
