Eh, then you had it the same way as I. Back before when I was a Spyro lunatic, I always had the though that Old Spyro and Ember married, had a kid - TLOSpyro - some ___holes stole the egg, TLOSpyro was born (story continues the same was as the TLoS story goes), New Spyro (and Cynder) meets Old Spyro and Ember, they defeat Malefor but Ghaul somehow survives and kidnap New Spyro and Cynder, they then become evil for a short time and "transforms" into Skylander Spyro and Cynder, Old Spyro and Ember saves them, New Spyro & Cynder returns to their normal forms, with their dark forms (Skyland Spyro & Cynder) "re-create" themselves as good little dragons.
TLOSpyro loves TLOCynder, SkySpyro goes with SkyCynder, with Classic Spyro goes with Ember. Problem solved. I actually had this though for a good while, but its been forever and I forgot about this entire plot.
