Eon is the exclusive Legendary skin that is obtainable by purchasing the Xbox One S Fortnite Bundle. You can only currently get it through this method, but people will likely be selling codes for it in the near future (be careful if you attempt to purchase through this method, you can easily get scammed). If you don't want to purchase a new Xbox, you can wait for the chance that they make the set available via an alternative method. For the Royale Bomber skin, they eventually sold a controller bundle that came with the skin.
You can check out the official announcement of the Xbox bundle here.
Here's the leaked information that was obtained by TrueAchievements which has now been confirmed:
