Why is Roxas and ven look alike

The only Reason Ven looks like Roxas is because, Ven Is another part of Sora meaning like another half like Roxas at the ending Sore absorbed ven making him inside him and then In Kingdom Hearts He became a heartless to save kairi making Kingdom Hearts 2 so then it's like reincarnation of ven is Roxas That's why they look the same So then Roxas looks talks like ven because hes like his recarnation for example:
Kagome is the recarnation of kikyo In another Anime called InuYasha
So then! Roxas is just a recarnation of Venn making him another other like Venn and sora but they became one well makes sense again because in kingdom hearts 2 Roxas became part of sora all over again but then that's what happened Now reincarnation ish dead o-o...
