Diomedes Musical Concept, what's relevant?

For the past year I've been researching and slowly working out an outline for a story covering Diomedes' life.

Now I was wondering, what do you think are the most important elements to his character? The themes making him unique?

Excluding the most obvious as him injuring Aphrodite and Ares, the Doloneia or Palladium Heist

Mostly wondering about more niche elements that may get overlooked 🤔

A personal favorite of mine is him meeting Aeneas in many different versions of the myths after his death as well as him reclaiming his urspured grandfathers home for him For themes him being compared to his father despite the less than favorable death of the latter And his seeming self control 🤔
