Heh; the color scheme strikes me as a sister potentially... given the scuba element could go with a plesiosaur or mosasaur or ichthyosaur.

As much as I love Dino’s I don’t know all that much about them and I really just stay with the well known ones but despite that I was thinking of a Plesiosaur but I’m not sure how you would put a diaper on one and I’m not sure on a girl because I’m a dude and I don’t know anything about women and to be honest because of that naughty stuff.

Heh; well if the character IS going to be an "anthro" character then the diaper problem is sort of a moot point since they'll have humanoid anatomy regardless, my aquatic furs for example.

As for the gender; ultimately whatever you're comfortable with. Personally I like having the variety, and ultimately; when it comes to writing a "good/interesting" character there isn't that much different between the two.

Exactly! I think looking around it’s definitely possible to put a quadruped in a diaper and an inflatable plesiosaur in a diaper would be unique!

I’m still not sure about Gender as I do feel most comfortable keeping the character male but variety is something i would like. Heck if I keep it a T-Rex I love the idea of an older sister for Zoran and Leslie!

Hehe; putting diapers on quadrupeds certainly works; but here's an example of what I meant by making an aquatic character anthropomorphic, same way Zoran is or my own sharks:

And yeah; if you're looking for uniqueness; dinosaurs are already a little on the rare side fur-wise, inflatable/toy ones and aquatic ones still more so.

Hehe; Zoran and Leslie having an older sis is a pretty cute idea too.

Nice character! I think an anthro could definitely work. And I do love the idea of a sister.

If you are using different colors and patterns, it's no longer the same character. Almost every character that you see here on FA got its inspiration from another character or combination of characters that the owner saw at some point. Very few are totally original. There's probably 10,000 husky characters in the fandom alone, and maybe 1,000 raccoons. One simply can't pick an existing species that no one else has used. You can make up a non-existent species, but even with those, they are almost always inspired by stuff that already exists.

I'm just a basic gray raccoon, which was inspired by my love for raccoons, and Disney's Meeko plush. Dozens of other furs have gray raccoons, and some look very similar to mine. It happens. Here is a good example of how close characters can be, without stealing from each other.

We each came up with our own characters independently of each other. We both happen to have one green and one blue eye. We both love to wear overalls/shortalls, and other cub clothing. Yet, we are still different. His eyes are reversed from mine, and thankfully, we didn't both happen to use the same name! That would have been very confusing. Even with the similarities, I had my raccoon character way back before FA started, and he had his for a long time too. Talking with the artist reveals that many of his real life interests and motivations overlap with mine, which is likely why our characters turned out to be similar in so many ways. But, we are sufficiently different enough to be uniquely ourselves at the same time.

Consider how many furs have skunk characters. Some are uncommon colors, but almost none are totally unique in their colors. Some have uncommon patterns, but the vast majority are basic black with one or two whites stripes. It is likely that most did not copy from each other though. It just happens to be what most real life skunks look like. Characters based on real life species, or even on combinations of species, are often likely to share similar characteristics, just by random chance. No plagiarism or copying is involved most of the time.

If your character had intricate markings and colors that were very unusual for the species, and they happened to be exactly the same as someone else's, it would probably indicate copying, but even then, it would be hard for someone to prove, unless one was an exact trace off of the other's art. Obviously, if you have different patterns and colors than someone, and the character is into different things, then you are different characters. There are plenty of real life people in this world who look like someone else too. One can't tell the other to stop looking the way they do, just because they are too similar.

You character reminds me of Barney, but it is also very different than Barney at the same time. If your character was 100 percent inspired by Barney, there would be absolutely nothing wrong with that. On the other hand, if you were going around claiming that you owned Barney, or the idea for Barney, then PBS would probably be sending you some very unwanted letters.

In any case, you should be safe. There's no harm in saying that your character was inspired by someone else's character. It would become a problem if you started claiming that you came up with the idea for the other person's character, or that you were the other person's character.

First off your character is adorable!

Also your insight makes me feel better about this since I felt meh about it 7 years ago and until now still felt unsure but I guess I’m ok in that regard! Don’t expect anything right away since I just got this all back to me yesterday.
