Ace and Waldo are siblings and Revvit and Click-Clack are cousins
Break-itt and Smash-itt are brothers. Similarly, Knock-itt (from season 8) is their sister
The two adult reptools from the forest (Splitter's debut) are husbands and Hudnut is their son. No I will not take constructive criticism
Zera and Tops are siblings too
Drillian and Auger are married and the twins are their children
Horn and Prong (Blayde's lackeys) are brothers for hire
Ty and Revvit are... ya know 😉
They became "official" in Volcano because that episode was way too emotional to not be a finale
I didn't ship Skya and Dozer at first but I'm now convinced they are dating
There's no way Ace isn't also some flavor of queer
The Dumps are in a poly relationship and Ton-Ton was their (oblivious) 4th wheel
Knock-itt goes through boyfriends like they're on sale. Scrap-it is one of her (many) exes. In the episode Part Kart, Scrugg was her current boyfriend
Ton-Ton has ADHD and Revvit has Autism
Skya is partially color blind (protanomaly)
All the main characters are young adults (Flynt repeatedly called Ty "kid"). Ton-Ton is the youngest. Maybe Click-Clack as second youngest. Him or Ace
Ty totally had anger issues but Revvit helped him work through it
Ty and Skya both have a self-sacrificing nature but Ty is much better and asking for and accepting help
Superchargers originally only worked on Trux (Ace implied she couldn't be charged) but was later retconned. I ignore the retcon
Ty tucks Ton-Ton in when he has bad dreams
