I'm gonna go with "Destiny Bane" since it fits more with the name of the other Z/X Cruel Dragon, Realm Razer. The one with Bane is also the later video, so it's possible that they retconned the translation since it is known that Japanese have some trouble when it comes to translating stuff into English.
