Munchlax #446
First in our final Abandoned Mascots section, while most of the entries in this category fall under the classification of legendary or mythical, Munchlax is the true poster child of abandoned mascots.
Snorlax’s baby counterpart was the first Gen 4 Pokémon to be revealed, headlining spin-offs (most notably Pokémon Dash) two years before Diamond and Pearl released. The Pokémon Company was very clearly positioning Munchlax to be a superstar, placing it at the forefront of marketing. The tiny sleeper even found itself participating in Super Smash Bros. Brawl.
Then, as Gen 4 wound down, so too did Munchlax. It’ll always retain some level of relevance due to Snorlax’s franchise omnipresence, but it’s destined to live in the bigger ‘mon’s shadow after its momentum to become more was squashed.
Victini #494
Victini was designed with the sole goal of making a Pikachu 2. It sports a similar body type and spunky personality to the franchise’s #1 player. Its human-esque personality was an unabashed tell that The Pokémon Company had big plans for Victini, as a scant few Pokémon are afforded such a luxury.
While Victini was warmly received and there were signs lightning could strike twice, it didn’t sustain. Perhaps this is in part due to its lack of visibility in the games with its tough-to-obtain mythical status. Ultimately, Gen 5’s more abundant Pika-clone Emolga found longer-lasting notoriety as Victini’s flame flickered out.
Castform #351
Like any Pokémon you can only obtain one copy of, Castform stood out as special despite its lack of legendary status. Its gimmick of changing forms based on the weather was a perfect companion for Gen 3’s overworld weather mechanics, and its simple design made it broadly lovable (not to mention ready-made for plush toy prime time).
Despite all this, it never found much relevance beyond its plot moment in Ruby and Sapphire. If anything, by becoming a wild Pokémon in Sun and Moon, it was robbed of its elusive 'only one' lustre. Maybe this was all The Pokémon Company ever had planned for Castform, but I can’t help but feel like there were broader plans that never panned out.
Glastrier #896, Spectrier #897, and Calyrex #898
Sword and Shield’s expansion packs showcased Game Freak’s ability to tell compelling stories in more open-ended environments. However, that feat wasn’t enough to give deer-like telepath Calyrex and its steeds Glastrier and Spectrier staying power.
The latter two feature some of the most rad horse designs in the franchise, and the option to have Calyrex ride them and gain new signature moves in the process made the trio quite novel among legendary groups.
People were just too clocked out to care, sadly. I imagine they would’ve gained greater notoriety if they weren’t allocated to a final expansion pack for a generation that many had already moved on from. Hopefully Game Freak gives these another chance to shine.
