Resolia is the lone female member of the Satano Blackies. Larson, the main protagonist was initially attracted to her until he realized she should be treated the same as her sadistic male teammates.
Resolia is a member of the alien Satano Blackies team that played against the Earth's Blue Planets team in a Battleball series that would determine who should rule the Earth. Resolia is the lone female member of the Blackies squad and she quickly garnered the attention of the Blue Planet's newest member, Larson who was attracted to her. Larson made passes at her when she came to bat against Larson at the mound but Resolia just mocked Larson. She would later take advantage of Larson's attraction towards her by acting coy and then attacking and striking him out by throwing the ball at Larson's chest. Larson who wasn't wearing any armour at that time was badly injured but also realized that all the Blackies players, male or female, should never be treated differently.
Resolia is a tall, slender but somewhat muscular woman. She is shown to be very athletic and physically strong but was also probably the weakest player in the series in terms of fighting ability as she was constantly beaten in one on one confrontations. She wears a technologically advanced visor that allows her to estimate the velocity and possible trajectory of a pitch, proof of the Satano Blackies technological superiority against the Earthlings.
After the loss of the Satano Blackies to the Blue Planets in their Battleball series, Resolia would return to join some of her Blackies teammates in the of the Battleball match between the Blue Planets and the Thunder Devils. She and her teammates offer their aid to the Devils who is now managed by the former Blackies manager. Their plans to sabotage the game, including trying to prevent their old teammate Samson from joining the game to play for the Blue Planets, failed. The Blue Planets would go on to win the match with Samson delivering the winning hit. A huge spaceship appeared at the end of the game condemning the acts of the Satano Blackies and the Thunder Devils teams. The ship then put up a huge encompassing wave of light that carried the Blackies and the Devils off the ground and draw them in. It is not known if Resolia and the rest of the aliens perished or were exiled to a distant place.
