Final answer:
In 'The Lion King,' the line "Yeah, we were afraid it was somebody important" is said by Shenzi, one of the hyena antagonists.
Step-by-step explanation:
In the movie The Lion King, the character that says, "Yeah, we were afraid it was somebody important," is Shenzi. Shenzi is one of the hyenas that serve as antagonists in the film. This line is delivered in a scene where the hyenas are talking among themselves after mistaking Zazu, the hornbill and the majordomo to King Mufasa, for someone more significant within the lion pride's hierarchy. The hyenas, as portrayed in the film, are known for their sarcastic humor and lack of respect towards the other animals, reflecting their status as outcasts within the savanna's ecosystem.
