The dangers of the apocalypse slowly chip away at his complacency and sensitivity, gradually forging him into a stronger being.

He doesn't aspire to be a hero, but he doesn't mind sharing a piece of bread as long as his own needs are met. The cockroach persists in surviving in the tight spaces of the apocalypse, until those spaces can no longer contain him.
