Pook

Pook is the Purple Team leader and Dark Trio Empire co-leader. His helpers uncovered Grellow Island in 11 BBT. He used that discovery as an advantage to quietly prepare for the attack. Purple Team started attacking Grellow Island couple of years later and finally destroyed it by the time Battle of Teams started. Pook didn't want his army to take part in the war, claiming it was drained after a clash with Grellowers. Therefore, he took the kidnapped people to Purple Island where he started training them for the army. It is unknown what happened to them later. Pook even kidnapped Rebecca, Elemon's wife.
