#things picked up again when they discovered blood types in early 1800's and slowly figured it out from there

This is a weird ask that kind of relates to the headcanon of Vasco being a blood donor.

What's is Vasco's and Machete's blood type?

Maybe they like hook eachother up and die if they have incompatible blood types.

That's the way to go. Kinda romantic?

(A reference to a show that I hope someone here gets-)

This has no bearing whatsoever and I'm picking these based on nothing.

It would be ironic if Machete was O-, which is the universal donor type. It can be given to anyone without adverse effects, which makes it very useful in cases of trauma and emergency when the receiver's blood type is unknown. But he wouldn't be able to donate because of his chronic anemia and low weight. Type O- can only receive O- blood.

I'm tempted to give Vasco O+. Over 80% of human population is compatible with it so it's always in high demand, and I like to think as a regular donor his blood would have extremely high chances of being put to good use this way. Type O+ can receive O+ and O- blood.

Neither of them are that uncommon, and it would be kind of funny if they had the same group by chance but were only halfway compatible.
