Yoshi was a terran who resided in the Gohbus Moon Refugee Camp due to the moon's planet being torn apart in a terraforming accident. This would result in the moon losing its orbit and drifting away from the system's star, rendering it uninhabitable. Unfortunately, there were not enough craft to get everyone off the planet in time.
Yoshi and his grandfather managed to make it to an available craft, though it only had room for one more. Yoshi's grandfather placed him on the ship despite his grandson's protests, arguing that "life is for the young." In a cruel twist of fate however, a meteor from Gohbus descended as the craft took off, destroying the ship and killing all on board, Yoshi included.
