Frequently used in Halloween-themed promotions related to the franchise, Gengar has been featured on multiple items of Pokémon merchandise and media since their introduction, such as a
Squishmallow plush, Gengar-themed
chocolate chip Eggo Waffles, and a Gengar-themed bed, produced by
Bandai, which utilized the species' extra long tongue and wide mouth as cushioning. Preorders for the bed sold out in less than two hours after its announcement. Described as "the most famous of the Ghost-type Pokémon" by
GamesRadar+, Gengar has been well received, placing 10th on
The Pokémon Company's
Pokémon of the Year poll which featured all Pokémon from throughout the franchise. In 2023, Centennial Media's
The Ultimate Guide to Pokémon noted that after compiling monthly search histories of
Google,
Yahoo and
Microsoft Bing, Gengar was the fifth highest searched Pokémon among internet users with approximately 113,500 average searches per month. The book ''Pikachu's Global Adventure: The Rise and Fall of Pokémon
noted the species was particularly popular with older male children who tend to be drawn to "tough or scary" characters. Cian Maher, writing for USA Today'' described it as an instantly recognizable symbol of the franchise and "one of those precious few 'mons that is unanimously loved by Nintendo and fans alike". Robert Grosso of
TechRaptor praised their "sinister" design as one of the best of the original
Pokémon games, feeling its
Cheshire Cat-like grin and red eyes embodied the series more "malign nature". He further called it "simple done right", noting a resemblance to a human shadow and an iconic face, which he felt helped fit what he saw as a
doppelgänger design philosophy. He also found that Gengar was "well-designed from every facet of its being". Zack Zwiezen of
Kotaku described Gengar as a great design, elaborating "It's simple, yet not boring or generic. Gengar is one of my favorite gen 1 designs". He further noted however that while he appreciated this aspect, its in-game Pokédex descriptions were often extremely unsettling in contrast to their described "prankster" nature, a sentiment reiterated by Alyse Stanley and Jhaan Elker for
The Washington Post in their own analysis of the entries in contrast to the franchise's normally upbeat atmosphere.
USgamers Kat Bailey described it as the "
Joker of the Pokémon universe: apt to turn on you at any moment", noting while its simplistic design and smile promised mischief, its Pokédex entries hinted at darker intentions.
Polygons Nicole Carpenter, meanwhile, stated that while aspects of the games could be dark, the descriptions given to Gengar left her conflicted with their cute appearance due to their short legs and round body, commenting that she "want[s] to squeeze him and hug him" despite being afraid of him due to his "sinister" smile. The duality of their character has impacted projects such as the film
Detective Pikachu, leaning into the "slightly scary" nature presented by their description while also presenting it as mischievous.
Kotakus Kenneth Shepard noted that while it was not a personal favorite of his, he agreed with the notion that it made an impact on the series, with Gengar serving as the blueprint for Ghost-type Pokémon that would be added later to the franchise. He believed it was among the most iconic Pokémon species in the series. Meanwhile,
TheGamers editor in chief Stacey Henley described it as "wonderfully expressive", arguing that the species was charismatic and had enough personality to be able to be the star of their own standalone game. Citing its portrayal in
New Pokémon Snap, where the species was demonstrated with more depth and allowed to play the role of a prankster with their powers, she felt it would be well suited for "the darker, gothic settings" not seen enough in the franchise. She added that while many Pokémon would shine with a proper focus from Nintendo, "few of them have the ingredients lined up as perfectly as Gengar does". ==References==
