Sonic: Christmas Blast (1996) is a movie my daughter and I recently watched together on Tubi. The storyline follows Dr. Robotnik impersonating Santa and stealing everyone's toys and money. When Sonic and friends find out they decide to take saving Christmas into their own hands.
This movie is directed by Blair Peters (Mighty Ducks: The Animated Series) and the voices are provided by Jaleel White (Family Matters), Garry Chalk (Power Rangers), Tabitha St. Germain (My Little Pony) and Jay Brazeau (Horns).
The Santa retirement opening was hilarious as was Dr. Robotnik's grand appearances. I adored how they took Robotnik's technology and made them Christmas themed. Seeing Tales is always great too. The ending is classic Sonic. He's never the best and most entertaining character, in my opinion.
Overall this is a very average addition to the holiday animated genre that is still worth watching for fans of Sonic. I would score this a 5/10 and recommend seeing it once.
