Here's a pack of 20+ characters that are standing and talking.  I broke them into individual and dual characters. There are some with white, designed backgrounds and some with transparent backgrounds.

I created these while practicing my AI prompting skills. The characters have been cropped, cleaned up a bit, and upscaled.

There may be some artifacts or image weirdness. That's the nature of AI. But you can crop those out or cover them up.
