The world of Pokémon is filled to the brim with lore and background stories. Unfortunately, a lot of character development and scene-setting didn't happen in the original generation, at least not through the games directly. Nowadays there are many side-quests and things to interact with in-game that can fill you in on some of Pokémon's crazy history.

One character we don't get to learn much about in Generation I and III is Agatha, the Ghost Master of the Elite Four. Known by many as the "creepy old lady," Agatha's character is actually a lot more complex and foreboding than she first seems.

To prove our point, here are some interesting facts regarding the Elite Four member that fans may not know.

10 She Has Conflicting Feelings Regarding Pokémon

We only get a small glimpse of who Agatha is within Pokémon Red and Blue but she has a much deeper backstory than most fans know. A lot of her personality and character development can be found in Pokémon Adventures, one of the manga series released in Japan that helps to better flesh out the lore of the Pokémon universe.

Through small tidbits in the games and the pages of this manga, we learn that Agatha strongly believes Pokémon were built for fighting and that's what they should do. Yet, as hard-nosed as that philosophy sounds, she has shown signs of caring before. In one issue, she saves a trainer's Seel from a toxic sludge and then comments on how despicable humans can be.

9 She's Absent In Generations II And IV

When you first meet Agatha, she's likely to strike a bit of fear in you. Up to this point, we were used to battling against angry-looking adults (Giovanni) and Psychic specialists (Gym Leader Sabrina) but Agatha offers us our first glimpse at a Ghost Pokémon Master. It's a truly alarming thought, and although Ghost Pokémon aren't as much of a threat in the original releases (as they should have been), it's still an imposing battle.

Because of her potential, trainers were excited to see her again in Generation II, only to be met with disappointment when she was inexplicably replaced by Bruno. She would return for FireRed and LeafGreen in Generation III and then disappear in favor of Bruno again in Generation IV. We're never really given a reason as to her absence.

8 She And Professor Oak Were Once Friends

Although you won't necessarily uncover much about their relationship in the first generation of the franchise, Professor Oak and Agatha were actually childhood friends (and rivals). It's hard to imagine the short-fused Agatha being friends with anyone but at one point she definitely had a soft spot for the Professor, at least, she did while he was an aspiring trainer.

It seems that Agatha lost her adoration and friendly vibes for Oak when he began to shy away from the training and battling aspects of the Pokémon world. In her old age, Agatha views Professor Oak as weak and no longer respects him.

7 Her Lineup Was "Poisoned" For More Variety

Agatha definitely got the short end of the stick when it came to team development. The developers definitely created a cool character that offered up a challenge (she was part of the Elite Four after all) but the lack of Ghost Pokémon in Generation I definitely put a damper on Agatha's potential power level.

To fill in the rest of her team, she was forced to take on some Poison types. Poison was arguably one of the worst types for Generation I, especially offensively. Agatha's only "real threats" lie in her Gengar and even they're stunted by a Ghost/Poison typing.

6 Her Team In Pokémon Stadium Features A Strange Addition

It seems that the developers of Pokémon Stadium felt that Agatha received a raw deal as well because they decided to give her an additional team member for the "Gym Leader Castle" sub-section of the game. The mainstays are present and you can expect to fight against an angry Arbok and a grinning Gengar, with Haunter, Golbat, and Muk filling in three other positions.

The strange addition comes in the form of Venusaur, which gives Agatha a bigger punch than most veteran trainers were expecting. To be fair, Venusaur is a dual Grass/Poison typing, so technically it's in her wheelhouse.

5 She Dislikes Blue With A Passion

In the Pokémon Adventures manga, there is one particular arc where Agatha goes from "slightly creepy elder" to "full-on criminal" when she first meets Blue (or Gary, to some). After discovering that Blue is Oak's grandson, Agatha goes into a fit of rage and decides to enact revenge on her former colleague for abandoning her.

The way she "takes things out" on Blue is extreme. She has her Gengar use Hypnosis on him and then proceeds to steal his life force with a Dream Eater attack. The manga-version of Agatha is a much more imposing and unhinged person.

4 She's Appeared In Ash's Nightmares

One look at Agatha and it's easy to understand why she might randomly pop up in someone's nightmares. She doesn't exactly look like the friendliest person around and she has an imposing glare that seemingly shadows a lot of pent-up anger. She's the type of elderly person that could keep an entire classroom of kids silent with a single demanding gaze.

In fact, in Ash's nightmare, that's exactly what she did. In the "I Choose You!" manga adaptation, Agatha is seen teaching Ash's class in a dream in which he is depicted as a simple school kid, rather than an aspiring trainer.

3 Gengar Is Her Favorite Pokémon

This one is kind of a gimme considering Gengar appears twice in Agatha's lineup (although one could argue that this is due to the lack of Ghost Pokémon in the earliest generations). In the anime, Agatha seems to have the strongest bond with her Gengar and is capable of using them in a variety of creative and interesting ways to gain the upper hand in battle.

Perhaps the biggest sign of her affection for this particular Pokémon is the fact that she keeps its Pokéball mounted on the end of her walking stick in some of the media variations.

2 She's Stronger In Pokémon: Let's Go!

In Generation I and Generation III, Agatha can be seen carrying 5 Pokémon. Her lineup usually consists of two Gengar, an Arbok, a Haunter, and a Golbat. The variation changes slightly between games and sometimes she can be seen with a Muk or a Wheezing.

The Pokemon: Let's Go! set of Generation VII offered the biggest change for the Elite Four Ghost Master. In both the Eevee and Pikachu variant, she's given access to an Arbok, Golbat, Wheezing, Alolan Marowak, and two Gengars with different move sets. All of her Pokémon are at least level 63. For perspective, the highest level she carried in Pokémon Red & Blue was a level 60 (with most only being level 56).

1 She Thinks The Pokédex Is Stupid

Agatha was always an openly competitive person that enjoyed battling and was good enough to make it to the final two of Pokémon Championships, where she would face her friend and rival, Professor Oak, for the crown. The professor would manage to beat her, prompting Agatha to enter "good sport mode" and offer congratulations. Unfortunately, Oak would respond by showcasing his plans to build the Pokédex and quit the training team that he and Agatha were part of.

This would definitely cause a "snap" in her, causing her to essentially disown Oak as a friend. To her, the Pokédex is a frivolous tool as Pokémon were meant for battle and battle only.
