Wow, headcannons! Do be aware that these are really cringe. And also, there may be shipping, but not irl. None of this applies to the real hermits and is just their Mc characters and my weird imagination.

When Keralis cant think of anything to say, he just compliments them. The others think its a little strange but also cant complain.

If X doesn't look like he's judging, depending on what happened, he is.

Ren is a huge idiot, but he somehow comes up with the best pick-up lines.

A lot of the Hermits are cross-dressers.

Grian suffers PTSD from what happened back in Evo (and YHS), but the Hermits help him get through it.

Ex is the biggest simp for Hels

Doc and Hels has huge anger issues

Ren has this thing where he cant feel emotions properly so sometimes he becomes emotionless. A lot of the time this "emotionless phase" happens at the wrong time, curtesy of his horrible luck, and he ends up coming off as rude. Luckily Doc, and his brothers (Impulse and Iskall) help him through it. Also, this was the result of a failed experiment. 

Scar and Grian aren't blood related, but they see each other as blood-brothers

Wels and Hels really don't like each other. Hels because of all the things Wels has said to him, and Wels because Hels has threatened to destroy the server.  (this has been heavily altered -21/7/22)

Hels has trust issues.

Impulse is painfully honest with everyone, whether its to help you, or to see you suffer.

Mumbo is the hermit with the most sanity Hermit.

Keralis is the most innocent and wholesome Hermit, and its everyone's job to protect him and his innocence. Although Tango and Ex try to ruin it. (this has been altered -21/7/22)

Doc and Bdubs are besties but also hate each other. While most of the Hermits find this annoying, some of them, like Ren find it extremely amusing.

Despite his size, Grian is the one of the strongest (Athletically).

Ren is freakishly flexible to the point it looks like he's broken something (like a bone), and he uses this as a huge flex. (Pun unintended)

Doc and Ren are 100% that competitive couple that has to be better than everyone else. Everyone has come to terms with this, except for the new girls. (they have now come to terms with this -21/7/22)

Cleo and Ren are the most dramatic in the server.

X is a sassy piece of cheese (shi-) when he's angry.

Hels is the type of person who would glare at you when you sneeze. It's creepy

Keralis is a goat hybrid and Doc has attempted to goat-nap him

Mumbo would respond to a very long, well thought out paragraph of text, only for him to respond with a "yes", or a "k" or something like that.

X doesn't take care of himself properly, which usually leads to one of the Hermits (Most likely Keralis) taking care of him. (this has been changed -21/7/22)

Stress is a morning person, while Iskall is very much not.

Hels never likes to admit it, but he's very proud of Ex. Same goes with Ex to Hels, but Ex has expressed it before.

Grian made up a group called "The Shipping Team" (Yes, very good naming, Asgore/10) which consists of Grian, Scar, Bdubs, Mumbo, Iskall, Keralis, Ren, Ex, BadTimes, Stress, Pearl, and Gem.

Iskall takes the longest to order food to see the look on the cashiers face. Ren would take the longest because he's very indecisive. (idk why I put this one in -21/7/22)

Grian became the Watcher Leader after Ren accidently ended up killing them. Nobody knows how- except for Ren of course.

Out of all the Hermits, Keralis is the least likely to kill you. (or Joe)

Grian is a cinnamon roll, but he could beat the hell out of you.

Bdubs and Keralis can literally read each others minds and talk to each other using facial expressions.

There are multiple sibling (groups?), and here they are. Iskall, Impulse and Ren. X and Ex. Bdubs and Keralis. Scar and BadTimes. Grian and Pearl (and the rest of the sleepy boys). Wels and Hels. Although Ren, Impulse and Iskall were adopted by Mumza and Dadza, and Keralis and Bdubs were adopted by Wither (she's a made up character I made and her siblings are Magma- another made up one, and Stress). Also Impulse and Iskall took care of Hels when Wels couldn't.

Grian can speak every language because of being a Watcher.

Grian is still very good friends with Sam and Taurtis, and felt very betrayed when Taurtis told him that he and Sam had already been married for 5 years, and haven't even told him. (It's not serious, he's just mostly joking around. But he isn't joking about being salty about it.)  (this has been heavily changed, because of the YHS lore I didn't really know too much about -21/7/22)

Hels is the most sarcastic person in the entire world ever. (this has been changed, and now that title belongs to Ex or X -21/7/22)

Scar looks so oblivious, but he knows a lot more than people think.

If any of the Hermits see anyone being homophobic, be ready to die.

Impulse is very depressed, but does extremely well at hiding it. (Even to the point of self-harm, but that's for different stories) 

Sometimes the Hermits get together and have Joe read to them. (awww I forgot about this head cannon)

Ren does a lot of Multiverse shenanigans, and all the Hermits were surprised when Ren told them about it, but it also explained a lot. Ren also time travels a lot.

Scar, Grian and Bdubs has a little builders club.

Keralis is X's favorite. (also the other hermits are very salty about this -21/7/22)

X and Ex can't get drunk due to the fact that they are Admin Void-Walkers.

Tango has a fear of rejection. :(

Doc and Ren are the musical buddies and sing together a lot. Although it's usually at 2am when they both can't sleep.

Ren is completely neutral. There is no in between.

X often gets asked "how do you control these people?". He just says "I don't have any sort of control over them, and I still wonder to this day how they haven't destroyed the entire multiverse yet".

Scar dies from kinetic energy so much that he doesn't even feel it anymore.

Hels can't die touching lava but he can drown in it. He also can't touch water otherwise it'll hurt him. (so basically, lava for him is like water to normal people, and vise versa -21/7/22)

The only person that can fluster Hels is Ex. (this has been changed because Hels- like me- gets flustered very easily when being complemented -21/7/22)

X and Ex are both derps.

Everyone treats Grian like a baby because he's so smol.

The Hermits heights are extremely exaggerated. (Like Doc is 7'8 while Grian is only 5'5)

Grian's wings are light purple that glow like enchanted elytra. (this has been changed, his wings are now parrot wings and when he's in his watcher form, his wings are still glowing but they're now a deep purple -21/7/22)

Etho is a big anime nerd a stays up for multiple nights on end watching it.

Etho and Ex's hair is naturally white (actually, Ethos hair is naturally ginger, but he managed to dye it white -21/7/22)

Ex doesn't wear a helmet off camera (very often)

Iskall is a huge meme.

Grian is sometimes hunted down due to the only person having watcher  feathers (that they know of), but they let him go in less than 10 minuets from either him being annoying or him killing them. 

Hels likes to go to a cliff in the overworld and it's one of the only things he likes about it.

Ren loves to listen to lovejoy so much that he's ended up going to the Dream SMP just to convince Wilbur to see them play a song irl.

Hels got turned into a watcher after he messed with them but he doesn't know it. (this has been removed, because I realized that it's too weird and also that title belongs to Pearl -21/7/22)

To add on to the last one, there needs to be at least two watchers existing, and they have to be different types. (One of harmony, and one of chaos.)

I'm sorry that I didn't include all of them! If there's anymore, I'll either do a part 2, or add on to this one. See you again sometime!
