Hmm.. it's a tough one. I think it turns out later that Enchantress has the Valkyrie trapped somewhere and can project her powers onto people at will.
This is true. The specifics are spelled out (pun sort-of intended) in Defenders v1 #108-109, if you're interested.
She does it in Hulk v2 #142 on Samantha Parrington, but it quickly wears off. However, Samantha Parrington does actually later acquire the Valkyrie powers and joins the Defenders for a while... so I think she should definitely be listed.
Samantha Parrington doesn't become a Valkyrie again until Defenders v2 #2, published in 2001. That's a long way off from where the CMRO is at now... but yeah, if we're being future-minded, Samantha Parrington should have an entry, much in the same way Brandy Clark
does; Clark would not become Starshine until long into her run of appearances in ROM, but the image that represents her is of her Starshine armor.
In Defenders #4, Enchantress again gives someone Valkyrie powers, but this time she doesn't reverse it and the true Valkyrie's powers and personality occupy the person from then on.
Sort of. Enchantress traps Brunnhilde's soul in Barbara Norriss's body, and vice versa—but since Brunnhilde's body is in the custody of the Enchantress, we don't actually see her/it until Defenders v1 #66.
I think the fix here is to have the "Valkyrie" entry refer to appearances of Brunnhilde's soul and to maintain separate entries for the souls of Parrington and Norriss as appropriate. In addition to the appearances currently listed for Barbara Norriss
, she appears in Defenders v1 66, 67, 68, 107, and 108.
It would probably be easiest to list Valkyrie in both, but also add Samantha Parrington to the listing for Hulk #142.
Definitely keep Valkyrie as having appeared in Hulk v2 #142 since (a) it is Valkyrie's first appearance, which is significant and (b) even though it is the body of Parrington that is being possessed, it could be said that it is Brunnhilde's soul that has taken possession under the control of the Enchantress.
Valkyrie's kind of the best, isn't she?
An unrelated note of correction: Jiamine Szardos, Morgana Blessing, Sara Wolfe, Wong, Clea, Margali, and Hannibal King appear as supporting characters in Doctor Strange v2 #58. Umar appears as a villain.
