It was before before Glory and Frozen existed.Ok isn't EW just the endless waltz abbreviation based off the movie?
And yea I didn't know the heavy arms upgrade was called Kai. Mind blown
Before then Early Types and Ver Ka's were one in the same.
With Glory Wing underwent a rebranding with Endless Waltz becoming a overall Brand.
Early Types/Ver Ka's became EW types and then you had all of the branding just carry forward with EW being added on so it looks like this.
Wing/Shenlong/Deathscythe/Sandrock/Heany Arms EW.
Wing Zero EW, D Hell EW, Sandrock Kai (Custom) EW, H Arms Kai (custom) EW, Altron EW.
Zero also no longer carries the Custom moniker. A side note is Altron didn't under go a name change as it was never actually called Nataku.
