I am Nobody

Yeah I know, I saw that somewhere and it didn't make sense. Besides Riku keeps using the Keyblade even though Sora has it, so they both got the Keyblade. It just SHOWS Sora getting it because he's the main character

I have seen a question about why the keyblade didn't look like Terra's: That's because they are shaped unique to each person, Riku has the way to Dawn because he is in between light and darkness. Sora has the Kingdom Key because he resides in the light.

The Keyblade chooses a person with a strong heart not pure light. Master Xehanort and Terra used the darkness, why didn't they lose theirs? Sora received his because he needed to protect his friends on the island, Riku got his at the time because he was trying to protect Kairi. Sora was connected to Ventus too who was asking Sora to be his friend and he wanted to help him as well. Besides, Lea receives a Keyblade too. He had a strong enough heart to retain his form when he became a Heartless and Nobody, which is how he got his when he came back.

Everybody says Sora received Riku's Keyblade because Riku gave in to the darkness. That doesn't make sense!
