Fridge Brilliance: Why does Malefor not care about his own fate? At first it seems that he just doesn't care but then he yells that he's 'eternal' during the final battle. Seems he thinks of himself as immortal. Now, if he was, or at least believed he was, he'd have survived the end of the world and lived into the new one. Malefor is power mad and has awesome destructive power, and a chessmaster. Put all that together and it doesn't seem to be a stretch that it was all an Evil Plan to survive the end and be around when the world was recreated, allowing him to do whatever he wanted to (given it's Malefor, that would cress into Fridge Horror).
Malefor tried to wipe out all the Dragon eggs from the Year Of The Dragon to prevent Spyro's birth. It's revealed later in the game he stole Cynder's egg to turn into a monster to free him, part of his plan from the start. In the third game, it's revealed it was actually Spyro who he needed to free him, not Cynder. This makes complete sense when one takes into account that it was part of his plan to kidnap a dragon to begin with. It's completely possible he intended to take the Purple Dragon from the get go, but modified his plan when it was discovered the Purple Dragon's egg wasn't at the temple.
Why did Malefor need the Destroyer to destroy the world when Spyro did the exact opposite on his own? Malefor guided the fate of his era, which ended. Spyro guides the new era. So Malefor needed an outside force in order to carry out his plan because fate laid in Spyro's hands now. Thus his efforts to convince Spyro his destiny was what Malefor wanted, Spyro guided the fate of the era and if he was convinced it would happen it would.
It seems strange that Malefor would lose it over Cynder breaking free of his control thanks to The Power of Love, but think about it. Malefor is obsessed with power and has an never ending hunger for it. Thus why he enjoys being a perfect chessmaster and manipulating everyone to do his bidding, it gives him power over it. In this one instance, for the first and only time in the series, something happened he had no control over. Thus why such a minor thing caused him to have a short Villainous Breakdown.
In A New Beginning, Ignitus narrates the story as you go along, at least for the first half of the game. Of course, we don't think much of it. But skip to Dawn of the Dragon and Ignitus is killed by the fire left behind by the Destroyer. It is later revealed after the credits that he became the next Chronicler. Could it be possible that Ignitus was telling the story of A New Beginning as the Chronicler?
Fridge Horror: The real Cynder is pretty kind hearted while Dark Cynder is an Ax-Crazy monster that has no qualms about murdering someone and the Guardians imply they were tortured while she held them captive. It's quite frightening to imagine just what Malefor's forces did to her to make her turn into that...
Also, she's the only dragon with real metal blades while others have bone weapons. While it might be a natural trait of her type of dragon, it's also just as possible, and more likely, the Apes did it to her. And she had them before being corrupted, when she was probably very young. Think about that...
Ignitus is killed by the fire left behind by the destroyer. At first, it doesn't seem that bad...until you realize he burned to death, what a horrible way to die!
Yeah...That swamp that surrounds the temple from A New Beginning? And how near it (if not in it) Sparx and Spyro's parents live? Take a look at what area is transformed into the Burned Lands in Dawn of the Dragon. Let that one sink in a bit. Tear jerking shall commence.
