Riku (Earth-101001)

Riku (リク) is one of the main characters in the Kingdom Hearts anime series. He lives on Destiny Islands with his best friends, Sora and Kairi, and all three of them dream of venturing from Destiny Islands to find out what worlds are out there.

Appearance
Riku is a teenage boy with silver hair with bangs, pale skin, bright blue-green eyes, and a slightly muscular build. Since he is a year older than Sora and Kairi, Riku is the tallest of the trio. Riku's hair was originally shoulder-length, but, his hair has grown longer until it reaches his upper back, he cut it short to the length it was when he was a child. Much like Sora, while his general appearance does not change much throughout the series, Riku receives several costumes and form changes during the course of his adventures.

Personality
Riku's personality is as strong as the land for which he was named. He is very strong-willed and confident, at times being arrogant. He values his friends deeply and puts protecting them above all else.

Riku is extremely competitive, and spent his childhood playing games, play-fighting, and racing with Sora. This competitiveness also made him easy to become jealous, especially during Kingdom Hearts, where he becomes very irked that Sora received the powers of the Keyblade while he did not, though he is not immediately vocal about it. This jealousy led him to behave aggressively to the people most important to him, and he began to act recklessly and harshly in an attempt to prove himself. He loses this childish jealousy streak entirely as he grows older.

He has a had an intense curiosity about the world he lives in (and what lies beyond it) ever since he met the foreign Terra as a child. His desire to know more became to consume him somewhat negatively over time. He has no qualms with going through the unknown to earn this knowledge, willingly stepping into a dark portal with an unknown destination, simply because he knew it may be his only chance to leave. After he does finally see other worlds, this desire subsides, and he finds comfort in his once-restricting island homeworld.

After the events of Kingdom Hearts, Riku becomes more humble, learning from the reckless mistakes he had made, and seeks to make amends. He becomes much more affable and mellows out. He has learned well from his mistakes in siding with darkness, and becomes wise and well-versed enough to become a Keyblade Master that Yen Sid can rely on.
