Amica Endura

An Amica Endura is a Transformer's long-term best friend. For a species that can live for millions of years, that sort of lasting friendship is a big deal.

A related-but-distinct concept is the Conjunx Endura, the equivalent of a spouse.

Fiction

IDW Generation 1 continuity

Nightbeat questioned Nautica if she had any Amica Endurae, or if her homeworld of Caminus practiced any sort of elective kinship. The answer was "yes" and "yes". slaughterhouse

Notes

• Nautica remarked most people would sidle up to that question, making it rather gauche to ask outright.
• "slaughterhouse" did not explicitly say what an Amica Endura was, leaving it up for us to work out, but it was confirmed later by James Roberts.
