They're both girls with two-tone hair!
Pretty simple game!
Find an OC that is similar to the OC above you, whether it be design-wise, personality-wise, story-wise, or detail-wise! I mean, anything in common works, even small things like if both OC's had purple tails.
If you're looking for someone with an alike OC to roleplay your character with, or just want a friend/partner/family member/etc for your OC, then you've found the perfect game!
Please try using a character with a complete story. If they do not have a completed story, atleast use a character who you presume would have something similar to somebody else's character.
If you don't get a reply in 24 hrs, try again using a different character.
And so on and so forth!
I will begin with my favorite character, Floss. What does your OC have in common with him? Floral powers? Floating wings? Large ears? Kind disposition? :O
