I give some basic prompt to give idea but these can be customized

prompt 1 : gintama_funny_face, open mouth, lightning energy in the background

prompt 2 : gintama_funny_face, blank eyes, angry, anger marks, eyes vein lines, impact lines

prompt 3 : gintama_funny_face, female focus, evil smile, open mouth

prompt 4 : gintama_funny_face, male focus, smile, teeth, impact lines

you can play and mixed all these keywords : blank eyes, open mouth, angry, anger marks, teeth, smile, evil smile, eyes vein lines, impact lines, lightning energy in the background
