What a great show and a great final season in my opinion. Please watch all 23 episodes from Shattered to From the Top. Sonic Prime has the whole friendship and teamwork trope as its moral but it works well.
This season 3 review has spoilers. I agree with it. We don't get many hero redemption stories like this one.
The two characters I relate to on the show are Sonic and Nine, the cyberpunk version of Miles "Tails" Prower, for different reasons. You will see why when you watch all three seasons.
