A serious-minded person is put into non-serious situations. (also includes characters that simply look serious)
Like the trope of the same name, these pictures present someone or something of incredible badass, coolness, or charisma, but all of that is made kind of funny by a cute or silly action or object. Despite this, they maintain a completely unamused look on their faces.

Put it simply:
'Baby Batman' - Badass Adorable
'Batman & Baby' - The Comically Serious
