Should I delete my old characters?

Specifically all the ones that aren't Zenith.

Long story short, the more I reflect on Amino, the more I realize that I forgot I have extra side characters here. Characters that I created only for a means of roleplaying as someone else besides my own OC, but given how all my friends are now on Discord and I barely come on here anymore, I debate I'd I should still keep them. Any thoughts?

This is being directed to all the veterans to this community and those who know about me. Any newcomers or people who don't know me, look at my wiki's to understand better.

Ps: if you decide on looking through them, newcomer or not, my wiki's still need edited and reworked. That is, if you want me to keep them.
