some people knew dr. doofenshmirtz was talented as soon as they met him: others needed some time to figure it out.

Explanation:

The sentence uses a colon to connect two independent clauses that contrast two related ideas, which is incorrect. A semicolon is the appropriate punctuation here to link two closely related independent clauses without a coordinating conjunction. Additionally, "it out" is incorrectly written as a single word "itout" and needs to be separated.
