Character Profile: Professor Felina Ivy

Professor Ivy lives in the orange Islands, and she used to have a pokeball called a GS ball. The island that she lives on is called Valencia Island. She would have had the GS ball transported to Professor Oak in Pallet town, but the GS ball is larger than a pokeball. She gives the GS ball to Ash and Misty. Brock, however, stays with Professor Ivy for a while.

In the second pokemon movie she calls Professor Oak about the changes that have been happening, and later in the movie she is riding in a helicopter with Professor Oak and Mrs. Ketchum. The helicopter crashes on an island that is in front of the three islands where Zapdos, Articuno, and Moltres lives.

Later on in the series, after Ash won in the orange league, Brock comes back helping out Mrs. Ketchum. They ask how come he's not with Professor Ivy, but Brock doesn't want to talk about it. The episode doesn't say why, or what happened.
