Yes they were specifically made for X10, at least visually. However, these characters are best used as melee characters, and at the moment, X9 can do melee better than X10.
These will eventually be made X10 compatible, although I have no idea when that will be. I know TGC is working at migrating features from X10 into X9, so I assume that X10 will also get updates too to handle melee characters that hold swords, and have different types of attacks (like the mummy for example).
