By the way which formatting of tittle is preferred as they are both used at the moment: "trap name - game name [region] "or "game name - trap name [region]"?
Because interactive figures have their own categories now, they no longer fall under the unofficial "Action figure naming rules" they previously had. The toy/action figure naming rules had series - figure name, and it was because they were all in just one category.
But now Skylanders have their own category (as do amiibo) they can start with "figure name - series name."
So the remaining entry for Kaos Trap in your post is correct, except it should have the colon between Skylanders and Trap in the figure series portion of the name.
