Appearances in official media
Most of Hassel's appearances in online and printed media is related to the Pokémon anime. The Paldea Elite Four's appearance received a lot of promotion in Japan during the "Terastal Debut" arc of the Japanese Pokémon anime in spring 2024. There were also a few interviews of the Elite Four cast, including Okiayu Ryotaro, who voices Hassel. Here is a list of various appearances and voice actor interviews, with external links included if the interviews are online. (If the links don't work, the website might've been removed (;_;) or changed.) Some of the media listed here might overlap with the official art and merchandise section a little.

Interviews and articles
- Nintendo Dream magazine (February 2024 issue)
- The Paldea Elite Four including Hassel got to appear on the magazine cover! A spread in the magazing focuses on them in the games, but it doesn't go deeper than short character introductions and their Pokémon teams. A poster of them was also included as an extra with the magazine. The artwork featured the key art of the game versions of the characters. The Elite Four also appears on one of the pages of the calendar (August) that also came with the magazine.
