Dipper

Dipper is Cosmo Ursa, the Sky Blue Ranger of the Power Rangers Cosmo Rescue.

Character History
Dipper is a young boy from Earth. Soon after his younger brother Wagler was born, they lost their mother Althea to illness. He is first seen with Wagler by Tapec and the others defying Gravastar's occupation. They are captured by Spaceo to be used as bait to attract the Cosmo Rescue Rangers, but Hyrtel, pretending to be his ally, rescues the two brothers. Hyrtel reveals himself to be a spy sent by Ladon and remind him of his bond with his older brother Gryule prior to the latter's betrayal and siding with Gravastar. Inspired by Hyrtel, Dipper decides to join the Rebellion. Hyrtel reminds him not to follow his brother's mistake. He later gains his own Change Sphere from the spirit of Ladon's predecessor, Arcas, allowing him to transform into Cosmo Ursa. Some time after joining, Dipper leaves the team temporarily for training at the Rebellion HQ to become a full-fledged Cosmo Rescue Ranger. He later returns to the team for the final battle against Gryule and Gravastar.
