So I previously asked a question of this forum and was delighted with all the responses I got.
Thank you all for your time and thoughts... however... I made an error in my original question...

So to back up and start again...

I am having a custom pen made with the theme/connection to Superman... It's a long story based on an idea I had after spending too long in Instagram.

The pen is more the opposite of what I originally asked!!!
What nib would Superman NOT use?
What nib would he cringe at with disgust?

I am comfortable using all nibs from UEF to 3B to stubs to italics to flex... But what should I put on an anti-Superman pen?

All suggestions gratefully received, even better with sound reasoning and a solid connection.

Thanks all for your time for my idiotic question.

p.s. I'm a Marvel guy!... Go figure!
