-I realized that we probably have similar interest in colorful game (or anime)-inspired OCs! Similar to the direction of Digimon or Danganronpa's characters, each character designs are very unique yet not out of place and still fits in the same universe.... Admittedly, I really adore character designs like that! (You also don't limit your characters to only humans either, which is great considering your "variety" trademark in designs.)
-I also like how each of the characters does look like they could fit in an actual video game design, specifically Kingdom Hearts, Megaman and the likes--that I feel like it should be a trademark of yours too ^^ (And judging from their profiles, they seems to have connection with D&D and video games too.)
-Your profiles are also simple, but straight to the point. The addition of stats and gameplay style is a very nice detail to your OCs, reminds me of those wikis you'd check for comparing stats and strategies of each of these characters.
Overall, your characters are very unique, but they remain in a consistent style and theme....which I really adore ;;
Edit: whoops, I forgot to mention about artstyle too--all of them have a solid choice of color pallete; nothing to saturated, but nothing too bold or flashy either! I don't see much issue in same-face syndrome and your pixels just enhance more of the fact that your OCs are based around the video games theme. (Again, I also see the variety in your characters--your non-humanoid character designs are fun to look at.) In other words, it's a fitting artstyle that really fits well with your OCs' stories~
