Hm, Trinary's Dashverse used Miriam for Rainbow's middle name. I like that, but I also like Athena, even there are probably more fitting goddesses to use. I do like the continuation of the Greek motif, the how majestic it sounds and also how it makes her initials R.A.D. Very fitting .

 

Of course Danger might actually be her middle name, you never know
