There will be a design change for "The Supreme Shapeshifter"

Since Dr. Golden "Prepare-Up!" as he took on a more elegant appearance,

From a tattered mantle and shoulder pads to a more imperial one, befitting
a look as elegant as his Master's design.

Plus some other distinct changes. The second "part" is a spoiler alert.

Also, I'm a little sick. But soon I'll be working on a certain art. 'Till next time!
