Many side characters in anime are sometimes more intriguing, charming, and funny than the main characters. Characters like Hunter X Hunter's Killua Zoldyck and Fairy Tail's Ezra Scarlet are fan favorites despite their secondary roles. Given the limited appearances of these characters in their original series, fans would love an anime series that focuses on them as the central character.
Be it painful pasts or questionable motives behind their actions, these characters' own series would put everything in perspective for curious fans. They'd definitely thrive as the main character of their own series and make audiences fall in love with them again.
