Iroh's relationships

Azulon
"You dare suggest I betray Iroh? My first born?!" - Azulon to Ozai in Zuko Alone when Ozai suggests he become Fire Lord instead of Iroh

Little is known and shown about how Iroh got along with his father. It is known that Azulon was a fierce defender of Iroh's birthright, was thus felt outraged when Ozai suggested that Iroh should be stripped of it due to Lu Ten's death, further suggesting the favoritism towards his older son.

Ozai
"Perhaps he can pass down to you the ways of tea and failure." - Ozai to Zuko on Iroh in The Day of Black Sun, Part 2: The Eclipse

Iroh's relationship with his brother was never given much clearing during the series. While the two neither met nor spoke with one another during the series, both of them have been clear about how they feel towards each other: tension and mutual dislike.

Lu Ten
"By beloved Lu Ten, I will see you again." - Iroh remembering Lu Ten during a flashback in Bitter Work

Not much is known about Iroh's relationship with Lu Ten, except that they were close. They loved to play together during Lu Ten's childhood. In a "Zuko Alone" flashback, it's revealed that Lu Ten died during Iroh's Siege of Ba Sing Se. The loss of his only son was so overwhelming that Iroh gave up on what could have been his greatest military achievement. In "The Tales of Ba Sing Se", it is shown that Iroh still cares deeply about his son, as he makes special arrangements for Lu Ten's birthday.

Lu Ten would have succeeded Iroh as Fire Lord had he not died in battle.

Zuko
"Even in exile, my nephew is more honorable than you." - Iroh to Zhao in The Southern Air Temple after Zhao tries to attack Zuko from behind

Iroh has always cared for Zuko. After his son died he thought of Zuko as his own. Iroh helps and advises his nephew, no matter the situation or cost.

In "The Waterbending Master" Iroh showed great sadness when he thought Zuko had died. In season two, Zuko and Iroh have to rely on each other more, because of Azula. Even though they are all they have have left, Zuko left Iroh for a short time, at the end of "Avatar Day". Iroh is not seen until "The Chase"; he and Toph have tea; according to "The Ember Island Players" Iroh wouldn't stop talking about Zuko. Before he and Zuko reunite, Toph suggests Iroh to tell Zuko that he needs him too.

During "Bitter Work", Iroh resume's Zuko's Firebending training and taught him how to redirect lightning, but wouldn't shoot lightning at Zuko due to the risks.

Iroh later decides that he and Zuko will be safe from Azula's grasp if they flee to Ba Sing Se as refugees. During their stay there, Iroh and Zuko work together in a tea shop in the city's Lower Ring, and they live together in an apartment. Despite Zuko's obvious disdain for his life as a refugee, Iroh remains patient and constantly encourages Zuko to look at the positives. He went so far as to encourage Zuko to find a nice "lady friend", and prompted Zuko to go on his date with Jin.

When Zuko learns that Aang is in the city looking for his bison, Iroh encourages Zuko not to go looking for trouble. When Zuko tries to capture Appa, Iroh stops him and insists that he has to stop letting others control his destiny, namely his father. This allows Zuko to instead free Appa and abandon his identity as the Blue Spirit, whom he was dressed as during the capture.

Zuko later falls ill due to his growing ethical conflict, and Iroh nurses him back to health, knowing that his spirit would be cleansed as a result of his better decisions. Zuko starts taking on a more positive attitude and the two are happy to work in their new tea shop in the Upper Ring.

Zuko and Iroh's relationship is jeopardized during the events of "The Crossroads of Destiny". Zuko gets captured by Azula and she asks him to help her conquer the city, which would earn Zuko his father's respect. Iroh vehemently insists that Zuko must do what his hear tells him and not to give in to another's demands. This fails when Zuko helps Azula defeat Aang and capture Ba Sing Se. Iroh is later captured and is clearly ashamed of Zuko's actions.

Throughout Book 3: Fire, Iroh refuses to speak to Zuko while in prison, and Zuko calls him a crazy old man. In an attempt to calm Zuko's inner turmoil, he reveals to Zuko his relationship with Avatar Roku and that he can help restore balance to the world. Zuko eventually realizes this destiny and joins Aang in his fight against the Fire Nation, but was too late to reconcile with Iroh, who had fled from prison.

Iroh and Zuko finally reunite prior to the arrival of Sozin's Comet, with a repentant Zuko begging Iroh for forgiveness. Iroh quickly forgives his nephew, stating that he was never angry with Zuko, but afraid that he had lost his way. Zuko affirms this, but says Iroh helped him find it. Iroh later encourages Zuko to take his place as Fire Lord, as he is the more suitable heir due to what he has learned from his mistakes. He prompts Zuko to ask Katara to help him face Azula, since she would not give up the throne that easily.

Iroh's guidance to his nephew gives Zuko the strength needed to defeat Azula and to claim his rightful place as Fire Lord, and the desire to restore peace and unity to the divided world. Zuko and Iroh are on much better terms now that the War is over, and the two are happy to be serving their friends tea together in Ba Sing Se after that city's liberation.

Azula
"She's crazy, and she needs to go down." - Iroh on Azula

Little is known about Iroh's relationship with Azula. While it was shown that Iroh cared for Azula when she was little, as seen when he sent her a doll from his siege at Ba Sing Se, that attachment has since deteriorated, going as far as saying that Azula "is crazy and needs to go down". Azula almost killed Iroh when she struck him with blue fire in "The Chase", and Iroh has constantly advised Zuko not to give in to her deceit and selfish demands. It was he who insisted that Zuko face her one final time so that he could claim his rightful title as Fire Lord. It is unknown what his feelings are about Azula's current mental state.

Toph

 * "I met him in the woods once and knocked him down. Then he gave me tea and very good advice." - Toph in The Crossroads of Destiny



Iroh met Toph by accident "The Chase" when she used earthbending on him during her temporary leave of Team Avatar. The two quickly made up. They had tea and talked about Toph's relationship with Aang and the group, as well as Zuko. They became friends and when Zuko was captured in Ba Sing Se Iroh came to her for help. It is safe to assume the two are still friends.

Aang

 * "So, Toph thinks you give pretty good advice. And great tea." - Aang to Iroh in The Crossroads of Destiny

There never was much interaction between Aang and Iroh. During the first time they met, in the series premiere, Iroh aided Zuko in attacking Aang, and after that, they didn't meet again for a while. Aang, apparenly didn't hold a grudge with him from his assistance with Zuko. Aang found an ally in Iroh during The Siege of the North, Part 2 when they were defending the moon spirit from Zhao. During "The Chase", Iroh helped out all of Team Avatar when they cornered Azula, but Iroh was hit by Azula's blue fire anyway. Iroh and Aang finally get up close and personal in "The Crossroads of Destiny", when Iroh went to request Toph's help in finding Zuko. While the two made their way towards the crystal catacombs of Ba Sing Se, Aang tried to get advise regarding the Avatar State from Iroh. Iroh said that because power is overrated, Aang had made the right choice in coming to Katara's help.

Team Avatar

 * "Goodbye, everyone. Today, destiny is our friend. I now it." - Iroh to Team Avatar in Sozin's Comet, Part 2: The Old Masters

Other than Aang, Zuko, and Toph, Iroh has had little real interaction with the rest of Team Avatar. Naturally, they were enemies while Zuko pursued the group, but as Zuko gradually changed his ways, Iroh came to respect the group more and more. He never actually fought them in direct combat, and thus few hard feelings exist between him and the other members. He sought the team's help to save Zuko from Azula in Ba Sing Se, as she had also captured Katara. He saved Aang and Katara's lives when Azula and Zuko tried to finish them off. Iroh later helped the team to determine how they should assist in Ozai's final defeat when Sozin's Comet arrived. When the War is over, Iroh seems to have befriended the entire team.
