Quackerjack can be a gypsy who is good friends with Rouge's group and Megavolt, Bushroot, and Liquidator are good-hearted guards like Shadow's group and Negaduck will be part of Ganondorf's guards who'll eventually become the new Captain of the Guards.
The Fearsome Four will be banded after Shadow's group, Megavolt, Bushroot, and Liquidator are rescued by Rouge's group and Quackerjack from drowning with arrow wounds.
In the climax, the Fearsome Four, after witnessing Spyro and Cynder revive Rouge from her coma from all the smoke she breathed in, will assist Spyro, Cynder, and Rouge on top of Notre Dame against Ganondorf.
And Negaduck, in the end, will be arrested with the other guards.
Remember how Julidizor2017 is gonna add in "Wherever You Are" in Chapter 10 of "The Eds of Notre Dame?"
I'm thinking of giving Spyro and Cynder a love confession song in Chapter 10 in "The Dragon Boy of Notre Dame," when Cynder confesses her love to Spyro, which motivates him to change his mind of leaving Notre Dame's bell tower to help Shadow's group find the Court of Miracles to warn Rouge's group of Ganondorf's "Morning invasion."
It's gonna be "I Have Dreamed" from the 1992 cast recording soundtrack version of "The King and I," sung by Lea Salonga and Peabo Bryson.
Except I will start it off with Cynder singing it first, confessing her love to Spyro, and then Spyro singing next, and then both at the song's end.
