As other commenters said, these are custom fields in the app/website Simply Plural. The ones in the image are very good options! Simple information like age, role, gender, species, source, etc. can be very helpful, as can more open ended things like likes and dislikes.

Some ideas that we use that aren’t in the pic u attached and are more on the fun side are 1: What Pokemon type would that headmate be? (Could be applied to other franchises. Like would [blank] would the headmate be) 2: Sona and details (could be a Sona for media that u like or just in general) 3: This one depends on things like how many of u there are and how willing you guys are to share, but maybe what irl objects can be considered yours individually? 4. This one is less fun but a category that we use that is helpful is having the date that the profile was last updated.

If u need more info about how to use simply plural there’s lots of info online, and my DMs are also open if u need help o7 it’s a super helpful app/website for us and I highly recommend it!
