Would you recycle your character

I’ve been thinking about this a lot, I’ve got this quirky gatekeeper..barely used it in a chapter but it feels too good to be forgotten

Asked a fellow author if they can use such character as it won’t serve me, they said the idea’s absurd but they’d think about it, made me wonder is it normal to reuse side character, power or items from other writers

gonna ask it here, will you be okay to let other’s reuse your side character, power system or items, nothing major just something good that can be reused
