My guess is that it would be a mix of human and thraxan lifespan. They would likely live longer than non-hybrids but would die far quicker than humans. IIRC the thraxans get born, take like a week to become adults, and then live like another 11.5 months or so before dying. So, I think they would quickly mature and then live for a while longer than thraxans. Just a shot in the dark but I think they would live like maybe 5-15 years.

Viltrumites live for thousands of years, it would make more sense to average out the Thraxan and human lifespan? Like a few hundred years.
