Strange question, but do you think Bowser’s species have long lifespans since they’re so resilient? Like real world turtle lifespans, or do they live just as long as humans?
I do, ye! While all Koopas are of the same species, Bowser’s species in particular are the strongest, largest, and generally the longest-living. I typically just call them the “Kaiju-Koopa”, but they could just as easily be called “Giant Koopas”. At any rate, all of the creatures in this world live much longer lifespans than what would be typically of ours. For easier reading:
Goomba: 100-150 years
Kongs: 150 years
Humanoids (toads, humans, mushlings): 200 years
Yoshi: 150 years
Koopa (Troopa, Lakitu, Boom Boom): 250 years
KaijuKoopa: 300 years
Magikoopa: 500 years, potentially longer if they have powerful magic
Divine (such as Rosalina): Immortal, however they will live a human lifespan should they give birth to a child, in which case their immortality is passed to the baby.
