It’s been a long time since I last updated the Panyan Universe 1/15 Robot Series—until General Tang reminded me just the other day…

Alright then—let’s whip one up! Little Fat hasn’t had any new gear to show off in quite a while, after all.

This design has been brewing in my mind for a while now. I’ve always felt that the inspiration came from EXIA’s signature weapon in Gundam 00—but I seem to recall similar concepts popping up elsewhere too, though I can’t quite remember where exactly.

Oh, and I also drew some heavy inspiration from the “Heavy Hammer Siege Cannon” I’d previously built as a dummy prototype.

In short, I’ve given it the name Thunder Dragon Variable Heavy Energy Cannon.

As for the story… well, I’m definitely going to save the big reveal for some pivotal moment—then suddenly drop several updates all at once hahaha (time to make a quick exit!).
