In this second box set of Ultra Sofubi we have the main heroes of the Heisei era. From 1996 Ultraman Tiga, from 1997 Ultraman Dyna, from 1998 Ultraman Gaia, from 2001 Ultraman Cosmos, from 2005 Ultraman Mebius, and from 2009 Ultraman Zero.
I have only seen a few episodes of their respective series but I have seen all of Ultraman Zero's appearances as he was created to star in a series of movies rather than a traditional TV series.
Each of these Ultras has several other forms and I'm not sure how Bandai decided which form would be represented here as there's a mix of base forms and power-up forms.
(Tiga)(Dyna)(Gaia)(Cosmos)(Mebius)(Zero)(Group Shots)
