Fireliliy, in my experience, lots of people here like ATLA! I like it, too, but I've actually only read the ATLA comics, so I can't base any of my opinions off of much heh

I LOVE ATLA/LOK SO MUCH!!!!!!!!!!!!! I'm obsessed too, and I have been ever since they came on Netflix and I just CaN't StOp ThInKiNg AbOuT iT!!!!!!!!!!!! The characters/character development are amazing, the plot is soooooo good, the animation is AWESOME, the voice acting is great and...yeah. I cannot find one single thing to complain about. AND the comics are amazing too. (I'm working my way through, and I've read the first 2 ATLA and the first LOK.)

Okay, here's some answers:

1. ATLA: Toph, Iroh, and Appa, LOK: Korra or Bolin (or also Toph)

2. "That's rough buddy" or "someone's being attacked by a platypus bear!" And also just the entire secret tunnel song

3.  YES: Katara x Aang, Sokka x Suki, Zuko x Mai, also kind of Toph x Sokka, and then for LOK: Korra x Asami, Bolin x Opal, and Zhu Lee x Varrick

4. Water (I took a quiz online, but also I'd pick water if I could) and I think I'd want all of the subcategories. I wouldn't want to use bloodbending but maybe in an emergency situation

5. I don't know, because I've never been in a role play before, but it sounds like a cool idea!

Hmm, I think I'll put my answers in too...

1. Who's your favorite character? (can be more than one) TOPH TOPH TOPH TOPH TOPH *does Toph impersonation for 10 minutes straight* But I suppose Katara, and Iroh too. Oh and Sokka. And Bumi. And Aang. *names most of the characters* And for TLOK, I think Asami and Lin. And Varrick.

2. What's the funniest line in the whole series, in your opinon?

Oof, hard choice. I mean, "I AM NOT TOPH! I AM MELON LORD! MWAHAHAHAHA!!" is great, but honestly.... all the Toph quotes.

3. Do you like any of the ships, if so which one? Or have you come up with your own?

Idk. I guess Korra x Asami, Toph x Sokka, and Katara x Aang. 

4. If you were a bender, what type would you be? (you can have the subcategories too, like metalbending) Hrm... Fire or Earth. Cuz lavabending, metalbending, combustionbending and lightningbending would be... really cool.

5. If I was to start a fandom ATLA/TLOK roleplay, would you join it? Well, I'd be making it so.... duh, yeah.

Oh my gosh, ATLA and LOK are THE BEST SHOWS EVER!!!

Yes, I would totally join an ATLA fandom rp! 

My favorite characters are Toph, Sokka, Suki, and Azula.

It's really hard to find the funniest line in the whole series but I really like the part where Sokka says "Oh no! I knew it was only a matter of time! Appa ate Momo!" and so on.

My fave ship is Suka (Sokka and Suki)

I would totally be an earth bender with metal bender

I think Sokka is the funniest character. 

1. Who's your favorite character? (can be more than one)

Hmm...I don't know. Maybe Suki? 

2. What's the funniest line in the whole series, in your opinon?

This is very hard :/ 

3. Do you like any of the ships, if so which one? Or have you come up with your own?

I like basically none of the ships from ATLA XD. From LoK, I like Korra x Asami and Kai x Jinora. 

4. If you were a bender, what type would you be? (you can have the subcategories too, like metalbending) 

A waterbender! 

5. If I was to start a fandom ATLA/TLOK roleplay, would you join it?

Yes, definitely!

Yay I love ATLA and LOK! 

I adore these shows so much! 

1. I love all of the characters so much. Toph is super cool, Sokka is hilarious and sweet, Zuko's great, Katara's awesome, Suki's also very cool, Aang is the sweetest, and Azula is honestly everything. I love Korra so gosh darn much, she's an incredible and deserves the world. I also think that the Red Lotus are very cool. 

2. Okay, I think for a bit here. The whole cactus juice episode is hilarious. One of the funniest parts is when Jet sees Iroh heating up his tea and then later confronts Zuko & Iroh at the tea shop where they've started working. Jet comes in and is like "These two are firebenders! I saw the old man heating up his tea!" and then some random dude is like "They work in a tea shop!". That cracks me up. 

3. I love Korrasami so much. It helped paved the way for more LGBTQ+ representation in cartoons and I'm so grateful for that(also the Korra comics have more Korrasami content so read this if you want some more, you can find them for free online). I also like Zuko/Sokka a lot and Sokka/Suki too. I also think that KyaLin is very sweet too. 

4. I would be a firebender. 

5. I'm not very good at RPs so probably not, but I think a lot of other people might like to join.

I also recommend reading the Kyoshi novels. They are so good! They're a little darker than the show but it's still wonderful. Kyoshi is such an awesome Avatar. 

AAAAHHHHH YEEESSSS THIS IS AMAAAAAZIIINGGGG

YES IT ISSSSSSSS 

1. I can't choooose. Zuko, uncle Iroh, Toph, Sokka, Momo, Appa, Pabu, Bolin, and Verrick are all up there.

2. I have to pick ONE??? Well, I will probably think of a million more later cause' I don't have a solidified list but hmm, for now I'll say all of Zuko's Iroh impressions are pretty amazing.

3. Definitlely nothing not cannon because I have . . . problems. I guess there is Maiko, Kainora, and Varrick x Jhu Lee.

4. Waterbender. :)

5. Probably but like I am really bad at commmitments so I don't know how active I would be.

I haven't watched all of LOK, but I loveeee ALTA XD
