Ray and Maya are in a photo in the background of the Bounty. The Time Twins were indirectly mentioned when Nya explains why Wu is a baby. Cole, Jay, and Zane's parents either appear or are directly mentioned in their flashbacks. Pythor literally is in Tales from the Monastery of Spinjitzu flashback, and was mentioned in Season 8 when Jay talked about past enemies who unleashed ancient evils. They all still exist and are canon. :P
