Sird

Sird is a character in Adventures

FireRed & LeafGreen arc
She worked with Giovanni on the Sevii Islands to capture Deoxys. Later, she fell from Team Rocket's helicopter after it was taken over by Carr, but she (unlike Orm) survived. She also tried to capture Deoxys by destroying its beam but all the main characters from the adventures and Mewtwo blocked the beam while Deoxys fled. In the Emerald chapter, Archie pointed out that Sird saved Maxie's life. That is why she got fired from Team Rocket because Sird is Team Aqua's #1 enemy and Team Rocket does not want to deal with afflictions from other teams.

Diamond & Pearl arc
Later on in the Diamond & Pearl arc, she reappeared in the dust clouds at Spear Pillar. She revealed to Mars, Saturn and Jupiter that she had been working undercover at Team Rocket to take Deoxys, so she could give it to Cyrus.

Later, she fought against Riley, after finding her aura on a Spybot used by Team Galactic but she fled during the battle.

She seems to know Jupiter already but not Mars and Saturn.

Trivia
She is the only high-ranked official who was with the three teams, Team Rocket, Team Galactic and Team Aqua.
