“Originally, their design incorporated an army tank motif, and the patterns that resemble treads above Zweilous’ legs are leftovers of that early design concept. Initially, the designs weren’t really working, so we put them on ice — but later, when orders came down for a powerful three-stage Dragon type, they were resurrected."
Getting a stealth jet is cool, but I hope they revisit a tank design for the next pseudo.
