Team Jagged was presumably formed after Jagged's induction into the Deathgalien.
After the Deathgalien arrived in Earth's orbit to use the planet for their 100th Blood Game, Jagged eagerly volunteered to be the first to strike and chose to lead the initial attack himself rather than send down one of his Players. However, he soon faced opposition in the form of the Doubutsu Sentai Zyuohger and was ultimately destroyed by them.
Some time following Jagged's demise, two of his Players, Dorobozu and Hunterji showed up at the Sagittari Ark to avenge their leader and become Team Leaders themselves to honor him. The two had about as much success as their leader did in defeating the Zyuohgers and both were destroyed by them as well.
