Sakurai Explains To His Fans Why Xenoblade's Rex Isn't A DLC Character.
Here Is The Explanation He Has Given Us...
“When it was decided that we were to create a character from Xenoblade Chronicles 2, the very first thing I thought about was to show and move Rex and Pyra at the same time on screen. But a conclusion that it’s impossible came at a match speed. I somewhat requested the team to inspect it, but it was impossible.”
“When we talk about 2 people who move as a single group, there are the Ice Climbers. They have the same looks and can only do the same things. When we tried Rex + Pyra, it was clear that we could not do an essential task to have their [data] capacity exceed a processing load threshold.”
“The system to have Rex as the main fighter and Pyra overseeing him was also determined to be difficult. The design was so complex that a lot of things would have to be done.”
“Rex would have to be moved on his own. But then I thought it would be better if we can change between Pyra and Mythra.”
