The "Babysitters Club," as nicknamed by Hawkeye, was a group of heroes gathered by Balder the Brave during the War of the Realms in order to keep his baby sister, Laussa, from being taken by her half-sister Sindr, the Queen of Cinders. Their formation was suggested to Balder by the Norn Skuld, who also told him to take Laussa as far to the West as possible. Using Wonder Man's Wonder Wagon for transportation and to hide in plain sight, they were being hunted by Sindr's accomplice Ares, the God of War. When the babysitters were on the road, Ares approached them in his all-terrain truck. Wonder Man broke the bridge where they were driving in half, allowing the group to escape.
Unknownst to any of her protectors, Laussa's godly and royal instincts prompted her to gather an army to fight in the War of the Realms, and she instinctively used her latent powers of mental manipulation to influence the "Babysitters Club" into visiting specific destinations where they could gather allies she would then influence too. The first of these locations was Bide-a-Wee RV Campground, a caravan park inhabited by Skrull desertors. As they ran out of the camper, the heroes were introduced to the permanent residents of the campground. They were invited to a sing along around the campfire. During the performance, Laussa caused a fickler of the fire to burn the guitar that Sol was playing, forcing him to reveal his true nature. The rest of the campers revealed themselves and attacked the heroes in order to keep their secret safe, but calmed down very quickly when they were introduced to Laussa after Death Locket took her out of the camper and the baby charmed them into backing down.
After hitting the road the next morning, the "Babysitter Club" came upon an abandoned Wild West-inspired theme park named Six Gun Territory. The group exited the RV and wandered around the town, where they were confronted by the Phantom Rider and other spirits until Druid's ability to talk to the ghosts revealed that their presence was related to Laussa. The Demon Rider later appeared to explain she had summoned the ghosts and they pledged allegiance to Laussa. They rode out of town in preparation for the War of the Realm's final battle afterwards.
Laussa next made the babysitters stop by Sterling Hotel & Casino, prompted by the need for funds for their trip, where they stumbled into HenchFest, a convention for super villain minions. When trying to make money at the casino by hacking the slot machines, a henchman recognized Hawkeye, resulting in a brawl until Simon managed to call a ceasefire. In the meantime, Ares had caught up with the babysitters after being guided to their location by Sindr. He abducted Laussa from the hotel room where she was being guarded by Thori.
The babysitters managed to retrieve the baby and confronted Ares. During the fight, the Demon Rider arrived with an army of the people from the locations the heroes had visited. She revealed that she had been influenced by Laussa, and had facilitated Ares' arrival by impersonating Sindr at the baby's request, so that she could influence Ares into fighting for the Earth. The babysitters discerned Laussa's powers and the fact that she had been influencing their entire journey. After Ares accepted to follow the child's will, the babysitters reactivated a S.H.I.E.L.D. Helicarrier hidden in Lake Tahoe and reached Avengers Mountain with their new allies and the baby safe. When Earth's heroes were gathered for the War of the Realm's final battle, the babysitters decided to move into the fight together.
- Hawkeye off-handedly calls this group "the Babysitters Club" in War of the Realms: Journey into Mystery #2 and 3, but the team is never actually given an official name.
