Droplets of what exactly?

Pran- Nathan

I swear I am not only going on designs, but that's definitely part of it (pretty big men ♡). Both are strong silent types with a lot of hate. Their general demeanor and outlook is similar. Plus, both canonically didn't speak (at least for a while) as kids (and the one scene of child Nathan reminds me of all the descriptions of child Pran). Both are some of the least academic/booksmart of the cast, also. Not everything fits (Nathan has a leadership role, passion, and a good relationship with his family, all unlike Pran), but they have enough strong basic similarities that I had to compare them.

Shiloh- Toki

Both are completely all over the map characters: are they sweethearts? Are they true genuine assholes? Are they somewhere in between? What is wrong with them? Are they okay? Both are very cute and childlike in presentation with a lot of unsavory traits underneath. Plus, both of of tend to be followers, going along with other people's random plans. Toki has more of a set characterization than Shiloh (who's kind of an enigma), but if anyone in the droplets cast fits Toki, it's Shiloh.

Everett- Pickles

I also debated Nate as Pickles but Everett works a lot better. Both are tiny guys filled with rage. Just anger and bitchiness in a tiny body. Pickles has had the most physical fights out of any character in his show, and the blood droplets kill levels confirm that Everett is the most violent of the jerks. Also, if Everett wasn't on constant watch by Nate, I think he'd absolutely be a party boy and drink a lot. The main difference in character is that Pickles has family issues galore and Everett is a momma's boy. Plus, Pickles is rarely an instigator and tends to just react to things, while Everett starts problems seemingly for fun. The comparisons are getting looser.

Bae- Skwisgaar

(I think JB also would've made a good Skwisgaar but I left her out of this) It's all about the confidence and self obsession. Both think that they are so fucking cool and want to lounge around and relax. They also both seem weak as hell (Bae is, and Skwisgaar seems to be, if his build and demeanor is anything to go on). Both have the utmost confidence in their own abilities and like to piss off their rival (either Nate or Toki) with that. The main difference between them is that Skwisgaar seemingly does a lot of work to be the best, he's constantly practicing guitar and he writes/works on the albums, whereas Bae kind of does jack shit and still thinks he's all that. Also, Bae's sex-adverse asexuality versus Skwisgaar's eternal ho phase lol

Jeremy- Murderface

I'M SORRY. This one is weird. I guess the main thing tying these two characters together is low self esteem. Most of dethklok and most of the xod cast don't really hate themselves- these two do. They also both have body issues, tied into that self hatred, that come up somewhat regularly. Both make everyone around them miserable, partially on purpose and partially because they are just Like That. The way they do it is different (Jeremy is a downer and Murderface just pisses people off), but it's the same general effect. There are a lot of differences, mainly that Jeremy is a germophobe and Murderface is nasty, but I had to assign someone Murderface and I wasn't losing the Pran-Nathan comparison so whatever ¯\_(ツ)_/¯

Lynn- Charles

Just in role more than anything. Guy in charge of a group of assholes, who really does care about those assholes and puts up with all the insults and difficulty they throw at him. (Also hot. They are hot.)
