9. The Greek Fire Arrow
Visually, the Greek fire arrow is one of the most impressive in the Green Arrow's arsenal. And if used correctly, it can also be one of Ollie's most lethal weapons.
Clearly, the Greek fire arrow - as indicated by its name - pulls its inspiration from ancient Greek mythology. Back during the battles of the day, the Spartans were partial to lighting up an arrow and firing it off in the direction of any who opposed them.
Over the years, a variation of the Greek firing arrow has been seen across many mediums and across so many fictional properties - and the Green Arrow and his world are most certainly included in the list of those who took inspiration from Greek mythology.
