The 'Mighty Protectors were already prestigious superhero team at the height of Captain Perfect's fame, thus making it an honor that Perfect was invited to join, although he declined, preferring to stay a solo operator. (COMIC: Interview With A Superhero) They had an associated team of young heroes in “training”, the Young Protectors. (COMIC: Epilogue to Destruction)
Despite nominally being more powerful and experienced than the Odds, the Protectors arrived on the scene late compared to the Odds when the alien Cosmic Solution robot threatened New York City, and refused to listen to the Odds' information about how the robot seemed to work. They attacked it at full power, not realising it simply absorbed the energy and used it to grow stronger. After they saw that attacking had made the robot grow, the Protectors decided that the winning strategy must somehow be to do the “opposite”: that is, nothing at all. They were immediately reduced to ash by the now-gigantic Solution before the eyes of the Odds. In the end, the Solution agreed to leave the Earth of its own accord after being called off by another agent of the Cosmic Order. (COMIC: Journey Out Of Misery)
