Cygames seems to have a habit of porting their characters around. There's still other characters from Shingeki no Bahamut that are cited with being from Granblue. Lecia, Yuel and Lily all have (Granblue Fantasy) attached to their names when they're originally from Shingeki no Bahamut. Shadowverse is even worse with over half of the cards being from Shingeki, though that's likely just to save on costs by using old assets.

Yes, I know that (I also know that I took too long to respond your comment -not that you were expecting a response or anything but- sorry about that :/), but it bothers me (as a former Shingeki no Bahamut player) that most of people here will think that these characters are from Granblue Fantasy when they're not and don't even know about Shingeki no Bahamut... I'm seriously thinking about start a topic in the forum to ask for a change of tags, to tag characters originally from Bahamut as such (change the *_(granblue_fantasy) for *_(shingeki_no_bahamut)), but for now, I'm still too lazy for that (will see for how long the laziness will keep being larger than the bother).
