Speaking of pinkei
I gave it a lot of thought and these two kinda got a lot in common

Their favorite color is pretty similar, they are both weird in their own way, they both have a way of feeling down, pinkies mane and tale deflates whenever she's supper depressed and hashirama..... Just gets sad easily they both have three other siblings although pinkie is the last born, they are both the odd ones out in their family, their fathers don't show any kind of emotion! same with the rest of the family for pinkie

When thinking this i used Tobirama for maud pie Kawarama for limestone pie and Itama for Marble pie, he looks like the shy type

They both have bone crushing hugs-so I've seen in fanfics and cant help but believe For hashirama
they also love to make people happy about themselves, They even both showed their families what happiness is like,

i think for hashirama

They are both loud and annoying  to their pears but they love them either way pinkei can be serious but not...... That serious like Hashirama in some cases he could still be a goofball in some serious cases

Also just a thought

I have a feeling that if Hashirama were to be creepy like creepy pasta

I believe his dream would crumble in a week or two

By his own hands.......
