It's hard thinking up another Stand. Well, not hard, but I usually don't make them for protagonists. It's hard to get my mind out of "this would make a good gimmick for a Stand fight" and start considering broader abilities.

Labor days is a 3ft tall humanoid figure clad in armor that looks like it's made of intricately engraved stone. A long wild beard of black hair descends from its face concealing helmet and covers nearly its entire chest. It has no right hand, instead possessing a hammer that glows read hot at all times. Labor Days it able to, by repeatedly and quickly striking something metal with its hammer, "forge" it into any different shape using the same amount of material. It can not create complex machine with many moving parts. Additional metal objects can be added together to create objects of greater size.

If any amount of alcohol falls onto Labor Days beard it is absorbed and the Stand undergoes a metamorphosis. The majority of its armor falls away to reveal a wild, ape like figure. It's Power and Speed both increase to A, but its Range, Precision, Durability all tank to E. How long this state lasts is based upon the purity and amount of alcohol absorbed. Labor Days can not "forge" in this state.

As for Macross, an extended war isn't exactly a lose state. The Zentradi enlisted take to culture like ducks to water once they get ahold of it and most of Earth gets glassed before the final battle anyway. Earth still wins so long as Breetai and his crew are judged as too contaminated by culture by their leadership and switch sides.
