We meet Hanumaan as Sugreev's minister in Kishkindhaa Kaand, when Sugreev, scared of Baali, saw Raam and Lakshman coming to his side. He sends Hanumaan to find out about those two gracious men. Hanumaan goes there in disguise of a Braahman and he talks to them in a very balanced language according to Ved and Shaastra. [That is what Raam's observation was.] That is why Raam said to Lakshman to ask him - "He doesn't look like a Braahman at all. Ask him "Who is he?"

Then only Hanumaan showed his real form and told about Sugreev. Lakshman also gave His introduction, so Hanumaan took them to Sugreev on Rishyamook Parvat. He was the medium of friendship between Raam and Sugreev.

When search parties were sent to search Seetaa, Hanumaan was sent to south, as all expected Seetaa would be found in south. So Hanumaan, Nal, Neel, Jaambvaan went to south in search of Seetaa under the leadership of Angad. At last they came on seashore and all got stuck there, as nobody was able to cross it. Then Jaambvaan reminded Hanumaan about his powers and he got his powers back in his body. He crossed 100-Yojan sea in one jump. 

As Hanumaan flew, Mainaak Parvat rose from the sea to give some rest to Hanumaan. Mainaak Parvat was the friend of Pavan - Hanumaan's father. Once Pavan saved him from other Devtaa. In olden days Pravat also had wings. They were also able to fly from one place to another. Since they used to be very tall they used to create obstacle in Sun and Moon's paths, so Devtaa thought to cut their wings. They cut the wings of most Parvat, but Pavan hid Mainaak Parvat and Mainaak got saved from cutting his wings. That is why he could still move from place to place. To show his gratefulness to Pavan he came to give some rest to Hanumaan. But Hanumaan politely said - "At this time I am going to do Raam's work. Later I will come and take rest." So Mainaak Parvat went inside the sea.

As Hanumaan proceeded, Devtaa thought to test his strength and wisdom. They sent Surasaa to test him. Surasaa came from somewhere and said to him - "Devtaa have given me good food today after long time. I will eat you today." Hanumaan said - "Maa, I am going to do Raam's work, I cannot stay back. Let me come back after knowing about Seetaa, then you can eat me." Surasaa said "No" and expanded her mouth to one Yojan. But Hanumaan expanded his body double the size of her mouth. Thus Surasaa expanded her mouth up to 100 Yojan, then Hanumaan reduced his size to a very tiny size equivalent to a fly, went into her mouth and came out immediately. He greeted her, she blessed him for his success and both went on their way.

Then there was a Raakshas who used to eat flying objects by capturing their shadow in the water below. He played this trick with Hanumaan also. He knew his tactics, so he killed him.
