Jakks Pacific surprises in 2021, by revealing small figures in cars themed for Sonic All Stars Racing. The first 3 will be Sonic, Tails and Eggman in their respective vehicles.
What's a bit odd about these is that the circle there claims they are "Die Cast", but the cars sure don't look like they are made of metal. The word DieCast generally MEANS it HAS to be made of metal, or, mostly metal. (As the thing that makes it is called a 'die', into which the material for the item is injected to form it. Yes, plastic can go into a die but the word diecast is generally not used for that. Hopefully the description is real, and the vehicles are made of real metal/quality. They're each bubble-carded and are not very big. The figures look ok from the profile view here, hopefully they're better than NKOK's effort at similar small figure-in-a-car. (That Tails was notorious for being plain-awful).
