Whether it seems intentional or not, there's characters who'll appear early on in a series and give you the impression that you'll be seeing a lot more of them.
One example of this is from Naruto. I remember watching the first few episodes of the anime and thinking that Naruto and Iruka's relationship felt particularly special and heartfelt, so it was a little shocking when I found out that Iruka didn't play much of a role in the series. He's still my favorite character and my main in all the Naruto games based on these early impressions of Iruka and the series.
