Originally, Janine's goal was to use Poison-type Pokémon just as well as her father. After becoming a Gym Leader, Janine hopes that by applying herself, she'll improve her skills and become better than both her father and (following her loss) the protagonist.
When encountered in her Gym, Janine hides behind the invisible walls that were installed prior to Generation I/III. To further confuse her challengers, the junior Trainers of the Gym are disguised like Janine. Once they have been defeated, the Leader will battle with a team of Poison-type Pokémon. Once defeated, she will yield the Soul Badge and a Poison-type TM: TM06 (Toxic) in Generation II; TM84 (Poison Jab) in Generation IV.
Like the other Gym Leaders of Kanto and Johto, Janine will leave her Gym from time to time in HeartGold and SoulSilver. Every evening between 4:00 PM and 6:00 PM, she can be found at the Pokémon League Reception Gate near Victory Road, on her way to visit her father and deliver his lunch (from 6:00 PM to 8:00 PM, she will say she is done delivering the lunch and offer to take a photograph with the player). She will give travelers her phone number, after which she can be called on Monday afternoons to arrange a rematch at Saffron City's Fighting Dojo. On Mondays, she can be found in the Celadon Department Store arguing with Falkner over which of their fathers is the superior Trainer.
Before the events that led to her employment as the Gym Leader, Janine hung around outside the Fuchsia Zoo. She will tell the protagonist of Pokémon FireRed and LeafGreen that Koga is teaching her how to use Poison Pokémon in an obvious reference to the previously released Generation II games.
Janine also appears in Pokémon Stadium 2's Kanto Gym Leader Castle. This is the only time in which her active team contains Pokémon not of the Poison-type. Despite this, all her Pokémon in Round 1 know Toxic, a Poison-type move and the TM she gives in the Generation II games.
"I'm on my way to my dad's house to give him his lunch. The Elite Four has no time to rest, day or night. It's such hard work, you know? Say! Do you want to exchange numbers?"
Yes: "Call me on Monday around noon if you want to battle!"
No: "You don't look like you're scared, but you are, aren't you?"
"Now you want to know my number, don't you?"
"Hello, hello, hello... Oh, hello, what are you up to? I'm just fine, thanks! Many of the Gym Leaders are much stronger than I am. We've just got to work harder!"
"Hello, hello, hello... Oh, hello, what are you up to? I'm just fine, thanks! My schedule's fairly open on Monday afternoons. Would you mind calling me back then?"
"Sorry? I’m afraid I can’t hear you very well. Must be a bad connection. Can you call again from somewhere else?"
Her calling the player
"This is Janine. How are you doing? Hey, can I talk to you about my dad? Only if you want to hear, though. Seriously? I might talk your ear off if I’m not careful!"
"This is Janine. How are you doing? See, I’ve been training with my dad since I was little--to be a Gym Leader. I haven’t even considered taking any other path, really. It’s my dream to someday become a better Gym Leader than Dad!"
"This is Janine. How are you doing? Falkner in Violet City... He’s talking about his dad all the time! Seriously, he’s such a daddy’s boy, he needs to become his own person sometime, you know? What do you mean, I should talk? Ha ha--mind your own business!"
Janine is the daughter of Koga, and the new Gym Leader in Fuchsia City. She does, however, leave town on many occasions to perform various jobs/simulations for anyone with the money to hire her. She was shown in Crossing Crobat to be in the middle of such a job, pretending to steal a large pearl to test the security at the Goldenrod Museum. After completing it, she pauses on a rooftop to wonder what she is doing with her life.
Her father, being both a ninja and a member of Team Rocket, had hoped to make her a member as well, both serving their master, Giovanni. But with Koga and Giovanni's disappearance, she was left alone and unguided. Searching for not just her father, but a master, Janine found herself in the same situation as Suicune, whom also was searching for a Trainer in its upcoming battle.
Suddenly, Suicune appeared before Janine, and challenged her with her Crobat. Suicune seemed initially caught off-guard by her tactics, but soon won. Before he left, Janine expressed her desires for finding her own master, just as she felt Suicune was.
Janine later fought against Falkner at the Gym Leaders Challenge. Despite overwhelming attacks, she forfeited the match when she left the battlefield, pursuing who she thought was her father. She never did catch the mysterious person, however, and it is unknown if they will ever meet again.
This listing is of Janine's Pokémon in the Pokémon Adventures manga.
Ariados is Janine's main Pokémon. He was first seen on a building with her. Later, Ariados was used in battle against Falkner. He defeated Skarmory using the sharp web technique but lost to his Noctowl despite slowing it down with webs.
Janine's Pokémon Cards listed with a blue background are only legal to use in the current Expanded format. Cards listed with a silver background are legal to use in both the current Standard and Expanded formats.
Chuang Yi mistakenly refers to her by her Japanese name, Anzu, rather than her English name, in Volume 11 of Pokémon Adventures. This was corrected in following volumes.
In the Generation II games, her whole Pokémon team was the opposite gender to her despite the 50-50 gender ratio. This was changed in HeartGold and SoulSilver, in which she has an all female team rather than an all male team like before.
In the English versions of the Generation II games, there is a grammatical error in the sentence where she gives the Soul Badge to the player. This was corrected in the remakes.
