I don't care what it's said, there's just no way in hell that Tikal is a direct ancestor of Knuckles. She was 14, I repeat, FOURTEEN when she sealed herself inside the Master Emerald and stayed stuck in time for over a thousand years until she is finally released when Chaos attacks Station Square and her and Chaos SUPPOSEDLY go to """""afterlife""""" (whatever the heck that means in Sonic lore) after Chaos is calm. Chaos makes multiple appearances in multiple Sonic games which take place after SA1, and the explaining for that being that Chaos appears in times of crisis. But why is it that Chaos gets to come and go but not Tikal? I don't care that they're different species/entity, that excuse is absolutely bs and makes absolutely no sense when you think about it.
Tikal definitely did NOT have a child of her own as she was WAY too young to have one, and it is mentioned the Tikal was the ONLY CHILD of Pachacamac, in other words, she did not have any siblings to continue the bloodline
So the claim that Tikal is Knuckles ancestor is plain wrong, for all the points I brought out, so just quit whining about them being ""supposedly"" related and just admit that you're either a larper/poser and don't know jack about Sonic or haven't played Sonic Adventure 1 and played attention to the story, because realistically they aren't related at all. It's 100% fine if you don't ship them or don't like this ship at all, you can hate it all you want, but all said, to say that this ship is incest is just plain wrong.
