Super Rabbit Boy is racing in the Super Grand Prix car race--but among the other racers is King Viking and his team of cheaters, and they will do anything to win.

Super Rabbit Boy gained his superpowers when, as a baby, he ate the magic carrot he found in the Wise Woods; now King Viking has built a time machine in order to team up with his younger self, Prince Viking, and prevent Baby Rabbit Boy from finding that carrot--so Super Rabbit Boy has to go back in time, and with help from an unexpected player, save his younger self and protect the timeline.

At age eight, David watched as his father was killed by an Epic, a human with superhuman powers, and now, ten years later, he joins the Reckoners--the only people who are trying to kill the Epics and end their tyranny.

"David and the Reckoners continue their fight against the Epics, humans with superhuman powers, except they may have met their match in Regalia, a High Epic who resides in Babylon Restored, the city formerly known as the borough of Manhattan"--

It is time for the All-Star games, and Super Rabbit Boy wants to be crowned the Ultimate All-Star Champion, but with so many contestants, including the evil King Viking, he will need help from Sunny and his video game console to claim his prize.

King Viking is doing a lot of evil plans at the same time so, with the help of Moon Girl and others, Super Rabbit Boy comes up with a plan to stop the supervillain's attacks.

As Nova, Adrian, and the rest of their crew face escalating crime in Gatlon City, covert weapons and conflicting missions have Nova and Adrian questioning not only their beliefs about justice, but also their feelings for each other.

Super Rabbit Boy's present to Moon Girl releases Queen Spooky and her army of ghosts, and Super Rabbit Boy is taken captive--so it is up to the normally evil King Viking (who does not like the competition of the ghost army) and especially his secret weapon, Robo-Rabbit Boy (switched to "Good" mode) to save Animal Town, release Super Rabbit Boy, and contain the ghosts.

When Sunny's father enters a video game he finds himself as the evil King Viking, but he is not very good at playing, so King Viking finds himself falling down and getting lost, and wondering if he will ever escape from the game.

As she nears her goal of avenging the Renegades, who overthrew the villains to establish order from ruin, Nova grows close to justice-seeking Renegade Adrian, but her allegiance to the villains could destroy them both.
