I support Kopa and Vitani! I believe Kopa is attacked by Zira, but Zira being the show-off that she is couldn't wait to tell her pride, however, Kopa was rescued and brought back to life. Because Simba and Nala saw no body they premised an animal dragged him away. Kopa returns once he feels the badness in his heart pass (e.g. Zira's death) If you want to find out more about Kopa then please read my fanfic, Kiburi Baadaye, or, alternatively, I could create an image explaining my story.

Glad to know I'm not the only one who supports KopaXVitani because they are a interesting couple

Cute. I personally love Kopa x Vitani as well.
