Does the premis of this comic book episode sound too corny?

So "Tetra" is the main villain. She has telekinesis and an nearly indestructible body. In Chapter 12 "Indestructible Aura" she gains access to the Shattered Soul Fragments of Jonathan Tanner, another mutant who can partially control time; Thereby gaining his powers. Then she confronts the heroes and initially easily defeats them. At this point, four of the five heroes give their powers to Malia so that Malia will have the combined powers to face Tetra in a huge battle across all of space and time. Tetra is eventually defeated and imprisoned inside the Sun's core, where she burns at a temperature quite literally hotter than Hell.

Problem: I only seem to have about 5 pages of content for this chapter, but I'd like it to be more like 20 pages.

I was thinking about selling partial rights so a cartoon series could be made from my book. For this battle, an epic soundtrack like "The Touch" by Stan Bush could be used.
