Also regarding Morph, I am not 100%, but I think this version of the character (and possibly the original version) actually started with the TV show*. Then eventually they would become a main character in Exiles, playing a version much closer to what the new show has. So I'm guessing they just stuck with the Exiles look for Morph. Which, I'm fine with. I'm a little confused as to how their powers work. They can not only look like whomever, but has their powers too? Fine, morph into Phoenix or Sentry, or Molecule Man or something and become a god. I also don't love how sidelined they are. I did like the little line they had with Wolverine when they turned into Jean Grey, but I wish they had more of a character arc in future seasons and not JUST be a quick means to tons of cool cameos.
* who was apparently a repuprosed version of a different character called Changling. I'm not super familiar with Changling or his impact on the X-Men comics, so I have no idea how similar they are beyond a similar power.
