With the many adventures Jinji and his fellow Ghosts have had over the years, it’s inevitable that over time, the crew have ended up meeting all sorts of characters outside their own circle. This page is dedicated to listing the outsider characters who have earned the title of “recurring guest”, either through having numerous appearances in several stories, or through regular interactions with Jinji and/or his fellow spirits. Where characters come from artists other than Jinji, I have endeavoured to link to the artist’s profile and provide a biography that is accurate to the character’s self-description.
This list is under constant construction and may not be fully exhaustive. Characters are in no particular order.

Aadvay
Artist: Cat (SilverBettaCCT)
The co-star of Two Shades of Green alongside Jinji, Aadvay (pictured here to the right of Jinji) is a Gengar from the beaches of Galar, who speaks in a mediumly-high pitched Australian accent. His fur is as wild and untamed as he is, but he’s really quite soft and sweet when you get to know him. Despite being a Shiny Gengar, he’s not really very keen on his shininess. He prefers to distinguish himself from other Gengar through the use of green paint he makes himself, which you’ll usually find smeared on his face as well as covering various appendages of his. He’s also a bit of a joker, and loves an opportunity to mess up others with his paint as well! Aadvay’s also very creative, and can sometimes be found painting sketches on nearby trees for fun. Surprisingly for a Gengar, Aadvay is actually a bit of a scaredy-cat who gets spooked very easily. He’s also rather gluttonous, and will eat constantly if given half a chance!

Kitty The Gengar Queen
Artist: Kitty The Gengar Queen
The Gengar persona of the Artist of the same name, Kitty is Jinji’s Best Friend Forever, the two having voice conversations online on an almost daily basis. Unusually for a Gengar, she is not actually a Ghost, having a physical body with mammalian skin and organs. Her sassy, badass, adult-minded nature belies a sweet, innocent and family-orientated heart; and Jinji and Kitty regularly joke about and even roast one another with silly jabs at one another in a playful and non-serious manner. After all, “you only roast the ones you love”!

Ghost and Ectoplasma
Artist: Kumada Panda
A duo of fun-loving Gengar who originate from another part of the Ghostly Realm but who have become regular visitors to both Jinji and Kitty. Ectoplasma — or Plasma for short — is a lighter-coloured Gengar who, alongside a Wobbuffet and the white ghost from Yo-Kai Watch who goes by “Wisp”, all star in his subscriber-only comics “Team Plasma”.

Ghost, meanwhile, is a slightly darker-coloured Gengar who often acts alone, but is just as much a fun-loving and mischievous personality as Jinji — and just as powerful, to boot! Whenever one or both of them get together with Jinji and/or Kitty, you can bet a fun and possibly prank-laden time is about to ensue!

Mallow the Garbodor
Artist wishes to remain anonymous
A Garbodor originating from a dumping ground many miles north of Unova, which was closed down after toxic waste was discovered to have been dumped there. The exact circumstances and timeline of how this Garbodor came into existence is unknown, though the toxic barrel in his side may well be a clue as much as it is a warning. An outcast for most of his life, Mallow constantly emits an extremely foul and toxic stench, far worse than most others of his kind. So proud is he of his stench, he will often seek out ways to make himself even more filthy and unsanitary! Despite his toxicity and grossness, however, Mallow is really a kind, caring soul who wants to be everyone’s friend. His charming personality has caused him to be a popular part of Pokémon World Online, just like Jinji; while his extreme toxicity means he is also treated like a God by the many Poison Pokémon who also reside in the Unova Dump. Mallow is also affectionate and a real hugger — which frequently causes Jinji to get into some pretty dirty situations whenever the two happen to meet!

Zain
Artist: Shahbaz Akihiko / “Zain”
A Pokémon Representation of a former PWO Player and one of Jinji’s longest real-life friends. In his PWO days, Zain was the leader of a number of popular PWO Guilds such as Team Aqua, Team Taka, and many of their successors. He is also a mutual friend of Mallow, above; and even once named him a successor to one of his Guilds, though the Guild later disbanded.
Today, Zain’s main guise is actually a Digimon rather than a Pokémon — specifically, a Veemon. However, in the past, Zain has taken on a number of different Pokémon forms. Perhaps the most famous of these was his Dragonite form, as pictured to the left. It was during his time in this form that Mallow and Zain schemed together to prank their mutual friend Jinji with a stinky machine, leading to their 2022 Birthday Prank, “Mallow’s Barfday Blast”. Thankfully, Jinji has long forgiven them both. 🙂
