So I have a lot of thoughts about these guys. And I figured I might as well share some of them. Honestly, there are a ton about Gula because he is literally my precious child. But I have a few for all of them.

- I think most of the fandom agrees Gula was a street kid. Like, it's just perfect. I have a few add-ons though.

- He was a thief. Like, that was his only way to survive. But he was low-key bad at it. Seriously, he was caught all the time. Not because he was loud or anything, he just had the worst luck when it came to stealing.

-But he was really good at picking locks. It was his best area. (Which is why nothing is safe in the foretellers tower if he wants it. He'll pick the lock on a window twelve stories up, don't tell him he can't get in that room.)

- Even though he was a thief and a street kid, he loved reading. He taught himself, so he wasn't the best at reading, but he loved just going into shops and staying there as long as he could reading books. (Sometimes he'd steal them, but only if he was feeling gutsy, he didn't want to get caught and banned from his reading places.)

-When he was taken in by the Master he formed a friendship with Ira over reading. He'd find a word he didn't understand and go find Ira and have him explain it. Ira was kinda honored that this small street kid that hated everyone would come to him with questions but he never said anything about it in fear Gula wouldn't talk to him again.

- Speaking of when he was taken in, the tower was never a safe zone when he got brought in. As previously noted if you told him he couldn't go somewhere he did anyway. Just because someone told him what he couldn't do. He still had that wild side from the street.

- He literally broke into everyone's room at least once, even the Master's. He took trophies too (though he eventually gave them back, except the plant he took from Invi's room. That is his plant now.)

- Gula also had this thing of sneaking up on everyone, without meaning to most of the time. Like you turn around for a second and when you turn around again he's just there out of nowhere. (I'm a fan of the headcanon everyone in the tower is convinced he can teleport.)

- Also a huge fan of him being a prankster. I love him just breaking into everyone's room to mess with their stuff. And just, no matter what they do they can't stop him. They have tried everything from barrier spells to barricading doors and windows, NOTHING stops this kid. It's half of the reason the other's think he can teleport.

- He's basically a human cat too. Pushes stuff off shelves, sits up on stuff to seem taller, likes being in enclosed spaces (aka he hides in boxes if available).

-Ok, Ava. She looks super sweet and kind, which most of the time she is. But like, she's not here to take your shit. Mess with her at your own risk man.

- I definitely like the headcanon she came from Destiny Islands. Super appropriate. I think she was probably also from a really well off family, and she spent a lot of her time helping others in town who weren't so fortunate. She just always had that kind heart.

- But the one thing she would never stand for was bullying. She didn't care what your excuse was, don't you dare even think of hurting someone who did nothing to you. She would seriously end you.

- She was also quite the prankster, but she had it so no one believed she was capable of that sort of thing so Gula and Luxu got blamed for her pranks.

- "I didn't switch your shampoo with pink hair dye, Ira." "Well, who do you suppose did it, Ava?" All the while she's laughing internally while pretending to be super worried.

- Luxu and Gula knew too, but no one believed them. (The Master also knew but he thought it was funny to watch them go to such lengths to blame anyone but Ava so he never said anything.)

- Ava was not a great cook, but nothing stopped her from trying. She wanted to do nice things for the others when they felt bad, so Ira would find her in the kitchen with a huge mess trying to make Aced's favorite food because he had a rough day training.

- This event usually resulted in the two of them cooking together, which was a major bonding moment for them. It also resulted in ingredients getting thrown at each other and a huge mess, but it was all worth it.

- And though she couldn't cook. She could bake. Like, there was nothing better than her cookies. And she loved to bake anyways, so the foretellers always had sweets in the tower and a lot of times she could just hand out sweets to all the keykids too.

- Ava was a major empath, like if someone was upset she knew. She was the only one who could tell when Invi was upset a lot of the time.

-She was also the only one who could calm everyone down every time with a 100% success rate. She knew how to handle everyone on instinct, like she'd tell the others not to bother Aced if he was mad. And she'd sit and listen to Ira when he was stressed. She knew all of Invi's favorite teas for when she was upset. Hell, she knew when the Master was upset and would ask him random questions about experiments to get his mind off things.

- Also, this girl was the type to have infinite comfort items. She had a huge collection of stuffed animals and tons of fuzzy blankets. If she was feeling down she would build a fort out of blankets and stuffed animals in the corner of her room and just hide.

- She would also do this with the others. Luxu was the most common partner.

- Speaking of Luxu, let's talk about this guy.

- Ok, I've made it pretty clear. He was definitely a prankster right up there with Gula. But his pranks were also accompanied by a huge amount of curiosity. Like, half of his pranks started as a "What would happen if I did this?"

-This included setting things on fire. He found the answer there was the fire spread quicker than expected and now Ira has to pay for damages.

- He loved explosives. Seriously. But also, he would accidentally cause explosions too. In the weirdest places.

- "Honestly, Ira, I was just minding my own business and then this beaker exploded. I didn't even touch it."

- He also had terrible aim with magic. Like, he couldn't hit anything if he aimed for it. A lot of the time he just fires off a spell and hope it hits.

- This a lot of the time resulted in more explosions because he hit something that wasn't a Heartless. Which was good and bad.

- Good because it killed a lot of Heartless.

- Bad because they had to pay for whatever he damaged in the process.

- (This is really funny when they come back and he's Xigbar. His aim is so much better and they can't believe it.)

- I'm not sure where he came from, but wherever it was it wasn't pretty so he sees these guys as his family. Like even more than the other's do. If you ask him he will call the others his siblings, even when just talking to the keykids he calls them his siblings.

- I love the headcanon he has accidentally called MoM Dad before. And it isn't a one-time thing. He has made the mistake multiple times and now when it happens no one even blinks, even though Luxu is super embarrassed about it. MoM just responds.

- Luxu definitely called Gula tiger despite being a leopard. No one knows if this was because he wanted to annoy him or if he really just didn't know the difference at first.

- Ira is the most responsible one of the group. Master included. This isn't headcanon I swear this is fact. Ira is the legitimate most responsible person in that tower at any point.

- He has records of all of the stunts the others have pulled. No one knows why, but they know the list exists. They like to have competitions to have the longest list. Gula and Luxu trade-off as the top placeholders. Occasionally the Master over takes them.

- He has some minor OCD. Everything he owns is organized perfectly. And if he's in a bad mood and someone moved something out of place it's enough to make him have a breakdown.

- There are recorded instances of this. Whoever moved his stuff is responsible for helping him fix it and also helping him through his breakdown. Sometimes Ava claims to have done it but everyone knows she's covering for one of the boys.

- He seriously overthinks everything. Like, even the smallest thing someone says to him makes him worry that the others hate him. Invi is the best at calming his fears since she's so logical. But Ava is a close second.

- He actually loves to debate with Aced. Even if they disagree, Aced has such strong opinions and will never lie if he disagrees. Ira really appreciates that Aced will be honest.

- Ira really, really can't stand lying. He doesn't care what you have to say or how mean it is, but don't lie to him about it. If you did something fess up and he'll probably not be angry, but if you lie you will face his wrath and probably regret a few major life decisions.

- He loves reading, as kinda touched on when talking about Gula. His room is full of books. Like a full wall of bookshelves. And even then a section of the library is all his books.

-Mysteries are his favorite. But he's read almost any book he could get his hands on. And he probably rereads everything too. Just to be sure he got everything.

- As also noted with Ava's section. I accept Ira is the cook out of everyone. It just seems perfect to me. (I'm also a fan of him being a vegetarian, hence he knows how to cook so he can avoid anyone making him eat meat.)

- Ira actually found out where everyone came from then taught himself how to make dishes from that location.

- Everyone was shocked beyond words when he perfected the dishes and made them for everyone. There were tears. Ira has never had a prouder moment since.

- I also like to think Aced came from the streets, which I have seen other people agree with me. It seems likely from his lack of social skills and always willing to fight.

- He definitely had a different strategy to surviving than Gula did. Gula was sneaking around but Aced was out punching everybody who got in his way. He even had this little group of other kids he would take care of.

- And he was super bad at socializing at first. He had no idea how to handle anything. He learned a lot from Invi. (She was the one who really took the time to teach him stuff.)

- But one thing he never picked up on was tact. This man has no filter. He thinks it, he says it. Which is both good and bad.

- Good because as noted, Ira appreciates the honesty.

- Bad because sometimes he either hurts others feelings or makes others mad. Sometimes both at once.

- Whenever this happens he gets really mad at himself and tries his best to make it up to whoever it was he made mad. He can usually manage with everyone with some advice from Ava. He has the hardest time with Gula, (because let's be honest this kid was the hardest to deal with for anyone.) but he definitely tries.

- He's like actually a really nice guy. He tries his best to help everyone. He does favors for everyone, no matter what it is.

- He's done some weird things for the others, just because they asked. He got Invi weird plant things, he's also collected all the items for pranks numerous times. He just wants to help everyone.

- This also applies to literally everything else. He just wants to think he's being helpful. The best way to keep him happy is to ask his opinion on random things. He loves feeling included.

-And as such, he loves including others. He goes out of his way to involve the others. Sometimes it annoys Gula but Aced has a good heart so Gula usually lets it slide.

- Also, this man has no fear. It almost makes him the king of stupid dares. He once jumped from the tower to prove he could. No fear whatsoever.

- I like to think Invi loves plants, I love that headcanon. So her room is just covered in all kinds of plants.

- Ok, she's really good at walking others through logical things. But she can't do the same for herself. If Ira is an over thinker Invi is almost ten times worse.

- She came from someplace really big. And like, she was taught a lot of manners and stuff, so she's the most formal of them all. (Ira is a close second.)

- Invi loves music, it really helps her relax. Specifically she likes string music, cello and violin. She can play the violin and the piano.

- Even though she can play she doesn't very often. Usually at night when she thinks everyone's asleep. (They aren't but they don't tell her that.)

- She loves tea, and has a collection. And a lot of it. An entire pantry in the kitchen is devoted to her tea.

- She even makes her own tea from the plants she owns. She's very protective over that tea.

- She knows everything that happens. Sometimes before it even happens. She just knows. Gula and Luxu have made it their mission to successfully prank her but they can not manage.

- She also loves to draw. Which she also doesn't do much of around the others. But she sketches a lot when she has a day off.

- She has sketches of all of the others with and without their masks. Only Ava has seen them. And she is sworn to secrecy with the blackmail that Invi knows she's a prankster.

- (Seriously Invi knows everything. Luxu swears she knows even more than the Master.)

- And since Invi knows everything, she is the queen of blackmail. She doesn't call it that, but that is what is.

- Seriously, don't make her mad. You will regret it. She will spill everything and you will live in shame for weeks.

- She's also the mom of them all. She keeps everyone in line (not just with blackmail).

- "No Ava, it's a Heartless, no matter how cute it is we can't keep it." "I don't care what he did Gula, you can't steal one piece from all of Ira's puzzles. Just steal one from one puzzle. That's more than enough."

- The only voice of reason sometimes.

- And everyone vents to her. All the time. It's really why she knows everything. She knows more about the others than the Master. She's such a good listener the others can't help but go to her.

- When one of the others have a nightmare (whatever the reason may be) they go to her to talk. And no matter the time of night she sits up and talks until they're ready to go back to sleep.

- And wow, she is super loyal. Like, you trust her with something and she will die before betraying that trust. Which is another reason everyone will talk to her.

- But at the same time, she's a snitch. If you don't specifically tell her it's a secret she will tell. And if she catches someone doing something they shouldn't be doing, the Master will know in seconds.

- Speaking of the Master, just a couple for him.

- He always has weird experiments going. And most the time no one has any idea what they even are.

- Sometimes he helps Gula and Luxu play pranks. Is anyone surprised?

- He physically can't say no to Ava. Like, she has some serious Bambi eyes he can't say no to. He needs Invi to help him stay strong.

- He does at least one special thing with each of the Foretellers.

- He helps Ira cook and come up with recipes.

- He has thoughtful discussions with Invi over tea.

- He reads with Gula. Usually silently, sometimes they debate over characters and events in stories.

- He helps Luxu with his explosives. No one is happy about this.

- He talks to Aced about recent events and how Aced thinks they should be handled.

- He helps Ava take care of whatever pet she has at that moment.

- And all of them value this time a lot. Seriously, he's not always a jerk.
