Plot
Zemerik, after having been repaired from his encounter with the Karmodials, plots his revenge on Battle Force 5 and the invasion of Earth. But amidst his army, a mysterious being disguised as one of the Zurk decimates the empire in lava, killing Zemerik and Zug in the process. On another Battle Zone, a female Red Sentient watches the chaos through the screens of a Quantum computer from inside a cave only to hear that her human apprentice has returned from the Sark Homeworld and watches the destruction with her. The human, disguised as one of the Sark, is Saphira, and the Red Sentient is Kyra. During their conversation, Helixion returns with not only a wave of content to see Kyra again but also one of relief that Saphira has completed her task. However, their celebration is cut short when they hear hoarse breathing coming from the side of the cave. Kyra fears that the patient could go into a comatose state unless she or Helixion finds a way to remove whatever device is in his body. Neither knew nothing about the human anatomy until Saphira jumps in to have know someone else who might know about it. It was time to bring in a new recruit, whom Saphira announces is her best friend, Grace.

On Earth, the latter is taking orders for her customers, especially Battle Force 5. One of which, Agura, is going through her laptop on the photos and videos of a certain girl whom she's also known over the years; Saphira Rodriguez. Vert and the others walk over to see what Agura was watching, Grace included. Agura tells the team that she was reminiscing about her fun times with Saphira when they were kids. Even Grace is familiar with the name. For Agura, Saphira and her father were visiting an old friend of his in Angola and that was how they met then.
