During last week's Super Smash Bros. Ultimate presentation, Sakurai explained how the team considered having Xenoblade Chronicles 2's protagonist Rex fight alongside Pyra and Mythra but it simply wasn't possible due to the limitations of the game.
Sakurai has now elaborated on this in his latest Famitsu column, once again explaining how the idea the team had in mind (of two different fighters at once) was ruled out due to technical barriers. In the end, it was decided the fighter would transform into two similar but different characters.
Here's the full translation, courtesy of Ryokutya2089 (via Siliconera):
“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.”
So this is why Rex didn't make the cut as a DLC fighter. At least he got to feature in the final smash scene for the new DLC fighter. What do you think of the latest two-in-one character? Were you hoping Rex would be a playable character? Share your thoughts down below.
