'''Petrel''' (Japanese: '''ラムダ''' ''Lambda'') is one of the [[Team Rocket]] {{tc|Executive}}s introduced in {{game|HeartGold and SoulSilver|s}}. In [[Generation II]], Petrel's role was filled by two separate unnamed Executives: one in the [[Team Rocket HQ]] and another in the [[Goldenrod Radio Tower]] disguised as the [[Radio Director]].

==In the core series games==
In {{game|HeartGold and SoulSilver|s}}, Petrel is apparently Team Rocket's master of disguise. He is first seen dressing as [[Giovanni]] and then battled in the [[Team Rocket HQ]]. After this, a {{p|Murkrow}} will imitate Petrel's voice to allow the player to progress. In [[Goldenrod Radio Tower]], he uses his disguise skills again, this time dressed as [[Radio Director|the Director]] of the Radio Tower.

Petrel's motives on Team Rocket are more mild-mannered, as he freely gives out information such as passwords and the location of the Director. He even considers himself a "nice guy" and hands over the {{jo|Basement Key}}. Though he believes that the player can't use the information, it is his giving out of this information that leads to many of Team Rocket's defeats.

Petrel in HeartGold and SoulSilver replaces two generic characters from [[Generation II]]: an Executive in the Team Rocket HQ and an Executive disguised as the Director in the Goldenrod Radio Tower.

===Pokémon Adventures===
[[File:Petrel Adventures.png|thumb|220px|Petrel in Pokémon Adventures]]
Petrel appears alongside the other three Executives. He, along with his teammates, take control of Team Rocket from [[Carr]], saying that they will stay true to {{adv|Giovanni}}'s intentions. In this series, Petrel is a master of disguise, and has the ability to quickly disguise himself as any person he has met.

Petrel uses his Koffing to attack {{adv|Silver}} and [[Clair]] at the [[Dragon's Den]], but loses and has his [[Plate]] stolen. Later, he attacks Silver and [[Eusine]] at the [[Johto Safari Zone]] to recover the Plate he lost. Using his Pokémon, Petrel gains an advantage over the two and nearly sends them off a bridge. However, Silver manages to rise up from the water, defeat Petrel, and take the two Plates he had with him. Using his disguise skills, Petrel manages to escape from Silver's grasp.

Later, he joins his teammates to finish their plan to capture the Mythical Pokémon {{adv|Arceus}}. They arrive at the [[Ruins of Alph]] and witness {{adv|Gold}} battling Arceus. After Arceus sends them all to the [[Sinjoh Ruins]], the Executives restrain Arceus and force it onto the Mystri Stage.

Using its great powers, they force Arceus to create the Legendary Pokémon {{DL|Pokémon of myth (Adventures)|Dialga}}, {{DL|Pokémon of myth (Adventures)|Palkia}}, and {{DL|Pokémon of myth (Adventures)|Giratina}}. While Archer, Ariana, and Proton start tearing up at the thought of pleasing Giovanni, Petrel reveals to Silver that he knows that he is the son of their boss. He reveals to Silver that he intends to betray his teammates by lying to Giovanni by telling him that Archer, Proton, and Ariana attacked Silver. With this information, Giovanni would destroy the three while Petrel would become Team Rocket's second-in-command for acting like he was protecting Silver.

Despite being blinded by Petrel's Golbat, Silver manages to escape his grasp and fly to where Dialga, Palkia, and Giratina and still being created. Using himself as a distraction, Silver manages to stall the Executives long enough for Gold and Crystal to destroy the Pokémon Arceus was forced to create. Now freed from their control, Arceus uses its powers to send Petrel and his teammates flying.

As Archer begins to lose his mind, Petrel becomes scared and decides to escape. Knowing that his teammates would stop him if he appeared as himself, Petrel decides to disguise himself as Giovanni so that he can walk freely. Before his plan can be executed, the real Giovanni arrives and stops him.

After the battle with Arceus had ended, Petrel attempted to escape once more by disguising himself as [[Bugsy]]. Gold quickly notices him, and Lance captures Petrel by having his {{TP|Lance|Dragonite}} lift him up in the air. When Gold asks how a coward like Petrel could defeat him, Lance reveals that it was because Petrel disguised himself as {{adv|Yellow|a Trainer with the same powers and birthplace as him}}.

==Trivia==
* In merging multiple Executives together, {{game|HeartGold and SoulSilver|s}} introduced a plot hole: Petrel is present in both the [[Goldenrod Radio Tower]] and the [[Team Rocket HQ]] at the same time. When the player first visits [[Goldenrod City]], a guard comments on the Director's changed nature:
:''"Sorry. Authorized personnel only beyond this point. It wasn’t that way before. There’s something wrong with the Director…"''
