fastfetch with custom ascii art generated by command

[batlopes]

I would like to know if there is any way to use a custom logo, since this logo is a random ascii art generated by another system command.
The only way I have been able to use this random ascii art generated, so far, was by saving it to a file and passing this file to fastfetch. But I didn't think it was cool to have to save it to a file, since this will always be done, since it is a random art.

The script that is generating the ascii art is: https://gitlab.com/phoneybadger/pokemon-colorscripts
