He grew up in the Oasis with Pumbaa and Simba, and together lived a carefree life until Nala found Simba and tried to convince him to go back to the Pride Lands with her. With the help of Sora, Donald, and Goofy, he and Pumbaa pull their courage together to help fight Scar's hyena army.
Pumbaa and Timon often say their motto Hakuna Matata, which means no worries.
On the first visit, Timon is not seen until Simba is seen in the oasis. At this point, Timon looks a little emotional to a degree, noting to Pumbaa: "Look at 'him Pumbaa, look at how he's grown. Why, when I rescued the little guy, he was only this big" and then lowers his hand to level with his knee.
He is eventually met by Sora and the gang and teach them about Hakuna Matata, which means no worries. As he leads a conga line of sorts with him at the lead and Sora, Donald, Goofy, and Pumbaa in the back, he chants "Hakuna", while the others respond "Matata". However, this carefree antic is put to a stop by Simba's fight with Nala about going back to the Pride Land.
Later, Timon helps the entire group to try and take down Scar, alongside Pumbaa. However, their attempts ultimately fail and they are cornered by Shenzi, Banzai, and Ed in a cave, which means it is Sora's responsibility to rescue them.
At the end of the First Visit, Timon is present and even delivers the line, after the gateway to the next world has been opened, "Hey! What's with the light show?", which shows other people can see the glow that is seen whenever Sora unlocks another gateway.
During the second visit, Timon is seen only scarcely, but ultimately helps Simba by telling him to "Live for today". He also gives some good advice before facing Groundshaker.
Timon is the erratic, wise-cracking, best friend of Pumbaa. Although short in stature, his personality is not. Timon is very self-absorbed, often claiming the genius ideas of Pumbaa as his own. Like Pumbaa, Timon has embraced the carefree motto of "Hakuna Matata," using it not only as a way of life, but also to cheer others up. Oftentimes, when the meerkat is in danger, he will cower behind Pumbaa as means of protection. Don't let that fool you though, Timon will gather up his courage to help a friend in need.
Timon is a small meerkat with light tan fur over most of his body, save for the front, which has white fur. The tips of his toes, his fingers, half of his tail, and his large nose are all brown. The ridges of his ears and his "eyebrows" are dark red and his eyes are brown. He also has light brown rings around his eyes. Timon's ears point downward and he has an unexplained, short, spiky head of orange "hair" on the top of his head. His back sports several horizontal, grey stripes. Timon's forearms are unnaturally thin, particularly when compared to the size of his hands. The fur on his chest and elbows is ruffled.
Timon first appeared in The Lion King, where he acts in a similar role to how he is in Kingdom Hearts II. He also has his own animated television series, Timon and Pumbaa (TV series), which Pumbaa co-stars in, and is the main character of The Lion King 1½, which tells the story of the original movie from his perspective. Timon reappears as a supporting character in The Lion King II: Simba's Pride.
