I have some questions. 1. Why do Roxas and Riku hate each other?

All very unimportant questions, but I'll do my best to answer.

1. The don't hate eachother. It was Roxas' duty as number 13 to kill Riku. That doesn't mean he hated Riku.

2. No. It's orginazation XIII, not XIIII.

3. He was fighting and it bent in an irregular location, causing it to snap, just like every other broken arm.

1) They do not hate each other. They fought because DiZ told Riku that, in order for Sora to wake up, he needed to bring Roxas to him. Now, the only way to bring Roxas (for he wasn't willing to lose his body) was by knocking him out. Hence, why they fought.

2) No, Riku was never in organization XIII. For some strange reason he wears the same clothes (the dark cloak) but that's it.

3) When was his arm broken? You mean on one of the final scenes of KH2? If so, then his arm was hurt because Xenmas kicked it while fighting.

First off I agree and disagree with fenix phoenix riku and roxas (a.k.a. Sora) don't hate each other but riku was confused why roxas had the keyblade especially oathkeeper
Second: riku just wore the black coat from organization XIII because he used darkness and light
And finally riku was not kicked in the arm but in the ribs and his arm was most likely broken when he first fought roxas

1) They don't hate each other, Riku fought Roxas because he had the keyblade and wanted to figure out why.

2) No, Riku was not in Organization XIII, He wore the coat because he had to accept darkness to beat Roxas.

3) When was his arm broken? During the ending cutscene? I thought he was just tired...
