Thanks to Scojo for the inspiration for this puzzle! Happy solving!
Solve online: CTC
Rules:
Normal sudoku rules apply. Place the digits 1 to 9 in each Row, Column, and 3X3 box.
Negators: Place 9 'Negator' cells in the grid so that there is exactly one Negator in every row, column, and 3x3 box. Each Negator cell must contain a different digit. The value of a Negator cell is equal to -1 times the digit it contains.
Killer: Digits in cages must not be repeated. Values in cages sum to the small number in the top left corner of the cage.
Parity line: Adjacent digits along the red line have a different odd/even parity.
Solution code: Row 1 digits from left to right.

Thx for the nice setup.
That was the perfect puzzle for me.
And yes there were other negator puzzles recently. If you use a row/column/box sum, the value if a negator digit is missing twice as much!
