9) Strong Supporting Characters

Strong supporting characters are integral to the Arrowverse's success. They support the main heroes, contribute to character development, and often have compelling arcs of their own. For instance, Martian Manhunter, played by David Harewood from Supergirl, brings wisdom and adds rich layers to his tragic backstory. Another example would be Caitlin Snow, played by Danielle Panabaker on The Flash, who balances being a brilliant scientist and her thrilling transformation into Killer Frost.
