Well, I may as well start off here.
So how did you come up with your OC Molly? Or other characters you've created?
Hmmm, if this answer becomes long I apologize <:]
When Molly became, well Molly, I have this thing that I always do when I see a character I really like or becomes my favorite character I try to make an oc based on said character. Mona is my favorite character in the WarioWare series so I wanted to make an oc that's sorta like her but not, after a while when I found her diary entries I read a part where she said she was an only child so I came up with the idea of her having siblings so I thought of a little sister cause it sounds cute :>
For the outfit I just took a huge amount of inspiration from Mona's outfit in Game & Wario, I really love that outfit so I just bootleg it and that's how Molly became Molly! :]
As for my other WarioWare oc, Aubrey, I took inspiration from Peppina Ramen (AU Peppino). I never have an overly anxious female character so Aubrey was the first and I really love her design a lot! I gave her a moon and star pin cause I really love dream theme stuff, I know her games are horror microgames but she got those from Molly since her themes are Dream theme microgames :>
Most of the time, all of my ocs don't use inspiration and are just made cause I had an idea. Some good examples are, Ms.Freaky, Charles, and my main persona Miss Dreamy! (images in order)
So it's a mix bewteen I either take inperation or just make someting that came out from my mind ^^
