Ariana

Ariana (Japanese: アテナ Athena) is one of the four Team Rocket Executives introduced in Pokémon Gold and Silver. Her name wasn't revealed until Pokémon HeartGold and SoulSilver.

In the games
At first, Ariana seems to appear in Pokémon FireRed and LeafGreen as an unnamed female Team Rocket Admin in the Rocket Warehouse on Chrono Island. After the player defeats her, she seems to understand their motivations for opposing Team Rocket and flips a switch to redirect the spinners nearby to give the player easier access back from the warehouse entrance. Three years later, Ariana is the only female Rocket Executive in the reborn Team Rocket in Johto. She appears to be Archer's second-in-command, although upon first challenging the player, she calls herself the interim boss of Team Rocket in place of Giovanni. The player battles her twice, first in the Team Rocket HQ, in a double battle with a Grunt on her side and Lance on the player's side (in Generation II, the player battles her alone), and again in the Goldenrod Radio Tower, where she is the last challenge before Archer. When defeated in the Team Rocket HQ, she notes that the player is strong enough to become an Executive if they joined Team Rocket, and after being beaten in the Radio Tower admits that she admires the player's power. Like the other Executives, Ariana was given a major makeover in Pokémon HeartGold and SoulSilver. Her identity was expanded on, her color scheme was noticeably changed, and her hair was restyled.

Pokémon Adventures
Ariana appears in the HeartGold & SoulSilver chapter alongside the other three Executives. She, along with his fellow teammates, take control of Team Rocket from Carr, saying that they will stay true to Giovanni's intentions. Ariana later ambushes Silver and Crystal to prevent them from intruding and interrupting their plans. Using her Pokémon, she manages to pin Silver to a tree while she faces Crystal alone. Despite the type advantage Crystal's Pokémon have, she is easily defeated by Ariana's powerful team. However, using his Rhyperior and the Earth Plate he obtained from Petrel, Silver manages to save Crystal and send Ariana and her Pokémon flying. Now facing Crystal alone, Ariana finishes off her Pokémon and explains her and her teammate's roles in capturing the Legendary Pokémon Arceus. Suddenly, Arceus appears in front of them and Crystal attempts to capture it, shocking the Generals in the process. Despite her tenacity, Crystal ultimately fails in capturing the Pokémon and is sent flying into a tree. The Generals chase Arceus down and find it battling Gold at the Ruins of Alph. Once Arceus takes them to the Sinjoh Ruins, the four Generals restrain Arceus and force it onto the Mystri Stage. Using its great powers, they force Arceus to create the Legendary Pokémon Dialga, Palkia, and Giratina. Believing they have pleased their boss, Giovanni, Ariana, Proton, and Archer begin tearing up. However, Silver distracts them by flying towards the Pokémon so Gold and Crystal can finish off the other Legendary Pokémon. Once they do so, Arceus, now freed from its restraints, uses its powers to make Ariana and the other Generals disappear.
