It might be worth opening these up for discussion a bit here or on the main boards, as these might occasionally be based on various myths, etc., which might also be of interest to add. Such a series has been brought up once in a while, however, so it might as well occur at some point.
In any case, while Haunter's entry does seem to be a reference to exorcism and related stereotypes, it might also be a reference to the move 'Lick,' or perhaps to the paucity of ghost moves generally, and in that sense might come across as an exaggeration to justify certain aspects of the game rather than something wholly affecting the PokVmon itself. While the choice of licking stands out as a strange action fitting your description, it might be that there was some awareness of that, as notice the seeming reference to the paralysis animation. It was also somewhat like a slow Poison Sting which might not hit many early opponents, and hence must whittle its opponent down with Lick, etc., if you wish to go there. There may have also been some discontent at the Ghost-type, after the Psychic-type issues of the first gen, continuing to be fairly marginalised with the subdued addition of Misdreavus. That said, there is something there when it comes to the move itself, and the Pokémon graveyard of Lavender Town, but by then it is quite mediated, in various ways, and not a first impression, as well as the paralysis thing still rendering that fairly humorous. In Pokémon, likewise, Tyranitar need not come across as that odd, as it combines stories of natural forces, such as peculiarly tsunamis, which are frequently converted into creatures in such contexts, with mythical rarity where they rarely appear but can cause damage, like dragons, plagues and so on.
That said, Frosslass and such might be interesting, if you notice the fairly clear mythological, and often Western, analogues to this that are probably being drawn on. A focus such as that kind of thing, on specific figures that seem to come up and their general nature, might be interesting, but focussing on exaggeration and occasional eccentricities might be limited in terms of their relation to the rest of the game. From dreams being eaten to dangerous pursuit, life is rarely kind to people who interact with Pokémon. Likewise, you could focus on the weirdness as related to battle, or unintended consequences that things might have in battle, etc. Drifloon is a bit friendly-ghost-ish, and half-hearted, while Rhydon is mostly a caricatured image of determination, or Calvinist, but you could perhaps make an amusing observation about how this could be inconvenient, although it's probably assumed to take place mostly in the wild, where Rhydon appear. At present, there might be a bit of a focus on their occasional traits, while to give that sense as an article you might want to differentiate between which are exaggerated versions of a trope, which can generally only be dealt with for a short amount of time, and which are for example actually seemingly scary in the context, rather than necessarily gravitating towards the usual suspects. People tend to find it weirder when the concept of things shakes them, as for instance with Lavender Town and the sudden introduction of ghosts, or the concept of Pokémon that can eat dreams, and so on, rather than either traits or oddities.
'According to the Pokédex' is a good title, although you might not want to base every article on one Pokémon given this basis, where quite a lot seem to rely on the others for their effect, and as such perhaps having two or three to begin with might make sense before determining whether to home in. This would also focus things on the commentary, such that you'd not be relying upon the entries themselves to have a major effect on the reader, and could rather be freer with those.
