I completed Giants and then opened a second file for Nightmare mode a long time ago. I just realized my Skylanders are not showing up in owned on Nightmare file. I have all my Skylanders ownership on the first file I completed. Can I take ownership of all my Skylanders in Nightmare mode as well and have both files have all of my Skylanders?

Yeah, just register them. They'll stay registered on the other.

i can confirm what clayface says, just take ownership again, it does not effect other save files.

This goes for all difficulties. I first started it out on easy for my 7 yr old. When I used the 2nd file for the medium level, I took ownership and it did not effect either files. We both have 109 registered skylanders and counting.

Yeah, most of my Skylanders I had before Giants came out, they were all owned by my SSA. I meticulously took ownership in Giants with each one, and they remain "owned" in SSA even when using them in SSA again. And before anybody complains "But this is a different game", I've done similar things in Giants. I took ownership of a few my nephews owned that I didn't in order to get Heroic Challenges and whatnot.

With Nightmare I specifically DIDN'T take ownership, I liked the idea of having a beat-Kaos-completed-game with 0 Skylanders owned. That lasted until I wanted to put the Knight's Helm on one of my nephews Cynders, turns out she's their second and has never been used so my game took ownership. Oh well.
