It's Maurice, but I decided to be lenient to a slight mis-spelling. 

What is Sonic's last name, according to the Archie comics? 

What were the name's of Sonic's adoptive parents in Sonic Underground? 

Which island was Sonic born on?

Not including Mighty & Ray because I don't think there's a canon timeline placement for SegaSonic the Hedgehog. 

Which of Sonic's friends did he encounter first?

This isn't a spelling test, just a knowledge quiz. The correct spelling is Chili Dogs, however.

Every Sonic fan should know this!

What is Sonic's favourite food?

Dan Green = Knuckles, Roland Wolf = Silver (German), Deem Bristow = Eggman, so Jaleel White was Sonic's voice actor!

Out of these options, who WAS a voice actor for Sonic at one point?

The answer is obviously really, it is a Sonic quiz after all. But yes, The Tornado is actually Sonic's plane! Though I think Tails deserves it at this point, and Sonic probably lets him use it when he wants anyway. 

The plane in the image is NOT The Tornado. 

The Tornado belongs to Sonic.

Hyper Sonic, Dark Sonic, Super Sonic, Darkspine Sonic and Werehog Sonic make 5!

Including mainline games only. Transformations not just a change in appearance.

How many forms has Sonic acquired over the years?

What racing game did Sonic cameo in before the release of Sonic 1?

Whilst Sonic certainly values all these qualities and more, above all else he fights for freedom. Freedom for himself, his friends and for every person on the entire planet.

Which of these values is most important to Sonic?

A short, relatively easy about Sonic the Hedgehog from, well, Sonic the Hedgehog!
