Sector A is the Amish Kids Next Door, and they don't believe in 2x4 technology or violence. Not much happens to their sector. They live in the country and are the only sector that uses real names. Their only operatives are Numbuh Jebadiah, Numbuh Rebecca and Numbuh Ezekiel.
In the ShowEdit
In Operation: A.M.I.S.H., Numbuh 2 gets sent to stay with them, where he finds out that they don't have a grown tree house. When Numbuh 2 asks Numbuh Rebecca about why they don’t have a tree house, he learns that Sector A wanted to wait for the tree to grow on it's own because speeding up the process would be "lazy". Enraged over how shortsighted they are of how tree houses are made, he brings out a seed that instantly grows them a tree house.
When the Treehouse has fully grown, the "Splinter Cell" attack them. Numbuh 2 runs to get a weapon, but the Splinter Cell block the way. Then, Numbuh Jebadiah throws a weapon over to Numbuh 2. He gets ready to fight against the Splinter Cell when he find out that they were really just nerds that wanted Numbuh 2 and Numbuh Rebecca to come with them and watch a "Doctor Time Space in the Continuums" marathon with them.
In Gamewizard's universe, they only had one appearance, in "Routine of the Amish". It is revealed their purpose is to make vegetables for their operatives to eat safely, and not have to eat the vegetables bought by their parents.
In that story, Numbuh Rebecca was mad that their sector had to be old-fashioned, but Jebadiah tries to tell her otherwise. When Numbuh 42 comes to take Rebecca to see Doctor Time-Space, she leaves with them. After she leaves, the Toiletnator attacks Sector A, and the two have to fight him without Rebecca. They are able to fend him off, but their crops are destroyed in the process. When Rebecca returns, she feels guilty for not being there, and sinks in hopelessness at all the hard work they'd have to do again. However, Jebadiah assures her it'll be fine if they work together.
