No any devotee is like than Hanuman ..
Ramanuraga( affection for Rama) of Hanuman ji is well known but his Krishnanuraga(affection for Krishna) is also no less. In Lanka, if he ended the lineage of the wicked Ravana in association with Lord Rama, he favored with Krishna and Arjuna in the Mahabharata war for the establishment of dharma and the destruction of unrighteousness. He himself was sitting on the chariot of Arjuna carrying the flag.
After the Mahabharata war, Shri Krishna asked Arjuna to get off the chariot. After Arjuna, Shreekrishna also left the chariot and also Hanuman including with flag, disappeared from chariot and Arjuna's chariot was destroyed by burning. Seeing this Arjuna was surprise , Lord Krishna said that your chariot had already been burnt to ashes before the divine arrows of Bhishma, Drona, Karna and Ashwatthama. Thats only one reason is that immortal Hanumanji was on your chariot, so your chariot was safe.
Very few people know that Hanuman ji celebrates Ram Navami every year in Ayodhya with great pomp. On the banks of Saryu he feed Bhandara with own hands to the Rama's devotees. To solve the doubts of Devarshi Narada, Lord Shri Krishna also sat with Naradaji in a pangat(row) in Ayodhya. Hanuman changing his form,he was serving Prasad with utmost devotion to the devotees of Rama , when his eyes fell on the feet of a sage. He recognized him and fell at the feet. He started saying - Lord, why did you come to Hanuman, I myself was going to come to Dwarika. Just I was waiting for your order. Devarshi Narada apologized to God and said that I am sad that I doubted your devotee that he would not recognize you in the changed form. After all Hanuman ji is Hanuman ji.
Hanuman ji is a devotee of Rama. He likes the same form of Prabhu Shriram. For ages and years, he contemplate and remember the same form of Lord Shri Ram. He knew that Lord Krishna and Lord Rama had no difference , yet when he met Sri Krishna, Balarama ji and Rukmani ji in Dwarikapuri, he expressed his desire to see them in their own form of Ramavatar and all three fulfilled his wish. While going to Vaikunth loka, Lord Shriram ordered Hanuman and Jamwant to stay on the earth and told them that he would give darshan to them when he incarnated in Dwapar. When Lord Krishna was accused of stealing the Syamantak Mani, he reached the cave of Jamwant in search of it. He also fought with Jamwant. It was during this war that he showed his Rama form to Jamwant. Jamwant became refugee and presented him to his beloved daughter Jamwanti, including Syamantak Mani. At that time Hanuman ji had become known that Prabhu had appeared to Jamwant ji.
At that time Hanuman ji was doing penance on Gandhamadan mountain. Even after thousands of years of penance between Treta Yuga and Dwapara Yuga, he did not see Lord Rama in the form of Lord Krishna, then Shiva ji reminded Lord Vishnu when he would give darshan to Hanuman. He was not satisfied to Krishna form, then he asked him to show his Rama form.
Very few people know that in Dwarikapuri he went on Lord Krishna's orders and destroyed the garden there as just like he had done in the garden of Ravana. He had also said to Ravana that the tree breaks by saying fruit, the monkey has this nature but he did not say this to Krishna.
Meanwhile, he also broke the pride of God's vehicle Garuda and Sudarshan Chakra. Garuda was proud that there is no one more powerful and faster than that.
When Lord Krishna came to know that a monkey was ravaging the garden of Dwarka, he asked Garuda to go with the army and tackle that monkey out of the state, but Garuda said that he is enough to tackle a monkey away. and he went to the garden alone. Did not take the army together.
There he used his force on Hanuman, then the mighty Hanuman ji wrapped him in his tail and he suffocated. Hanuman ji left him after his pleading .
Garuda ji rushed to Lord Krishna and said that Maharaj is not an ordinary monkey. Then Lord Krishna said that give him my message that Lord Rama has called him. By the time Garuda reached the garden, Hanuman ji had reached Gandhamadan mountain. After reaching there, Garuda gave the message of the Lord to him and also said that he should sit on his shoulder, he would bring him to the Lord as soon as possible. Hanuman Ji said that you go, I am coming and Hanuman ji reached Lord Shri Krishna before him. There he saw his in the form of Rama. Seeing Satyabhama sitting next to him, he said where is Mother Sita and what maid has you kept in her place. Satyabhama's ego went away. In fact, when Lord Krishna had given the Parijat tree to Satyabhama by bringing it from heaven, then she had an ego that the , she is only most beloved wife of God .
Shri Krishna had broken her arrogance through Hanuman. The arrogance of Sudarshan Chakra was also broken by Hanuman. At the time when Garuda ji went to call Hanuman, at the same time God told Sudarshan Chakra that he should stand at the door and not let anyone come in. Sudarshan did the same but Hanuman, not wanting a delay of one minute from Lord Rama, pressed the Sudarshan Chakra under his teeth and when Krishna asked that no one stopped him at the gate, he removed the Sudarshan Chakra from his teeth. Put it at the feet of God and said that it was becoming a barrier in my with you.
Meanwhile, Garuda ji also came. Seeing Hanuman before him, he realized the inferiority of his flying speed. Balarama was also defeated by Hanuman in a mace battle, but he did all this with without arrogance. Mahabali Bhima's ego was also broken by Hanuman on the Gandhamadan mountain. He could not move the tail of Hanuman. The skills of war that Hanuman had taught Bhima were very useful to Bhima in the Mahabharata.
