Below is a list of characters whose reality does not have an official designation and we do not feel the reality is defined enough to assign a TRN to. NOTE: The list may also include characters whose home reality is totally unknown - they are only shown outside their reality with no indication of where they are from.
Valkyrie was among the characters called up by a time projection by Justice Love to show that even without She-Hulk's intervention another super-powerful character could solve the situation involving criminals with super powers.
Valkyrie was a member of Dr. Strange's Defenders when they were approached by an alternate realityReed Richards who came to them to see if Susan Storm would be allowed to join their group in order to hopefully avoid a possible future where she would have been killed if she stayed with the Fantastic Four.
The Vanguard were killed by Trenton Craft's telekinetic powers, after the existence of Vanguard had been revealed to foreign agents. This reality was inserted into Trenton Craft's mind by Retcon convince him he'd killed the Vanguard to allow the to escape.
During a vision Thanos had while in the God Quarry, he was a member of the Avengers along with Vision. When Thanos realized that the illusion wasn't what he wanted, he killed all of the Avengers, including Vision.
