Mr. Smoothy is a restaurant franchise that serves smoothies. Ben and his team are its frequent customers. The franchise has 22 outlets in Bellwood with an addition of an inter-dimensional Mr. Smoothy.
Mr. Smoothy serves an exotic and often strange assortment of flavors, including:
- Chocolate and Carrot
- Mango and Blueberry with extra echinacea
- Lamb and Sardine: an all-meat flavored smoothy seen in Ultimate Aggregor.
- Grasshopper: It's latest flavor, which is a favorite among Galvans like Blukic and Driba.
Ben is infamous for drinking numerous amounts of them whenever he goes to Mr. Smoothy, drinking a collection of strange flavors, only to burp unpleasantly loud. In Vreedle, Vreedle, the Vreedle Brothers destroyed Mr. Smoothy and in the episode In Charm's Way, the restaurant's iconic mascot was brought to life, only to be drunk dry by Murk Upchuck. It was again destroyed in Greetings from Techadon, but was rebuilt by The More Things Change: Part 1.
Since So Long, and Thanks for All the Smoothies, after the universe is destroyed by the Anihilaarg and recreated by Alien X, in the new version of the universe, Mr. Smoothy's mascot, colors and logo are different.

- After Ben rebuilt the Universe in So Long, and Thanks for All the Smoothies, Ben says that the restaurant's smoothies taste different to how they did earlier. This was the reason that in Universe vs. Tennyson, Ben admitted his failure in replicating the Mr. Smoothy's flavor.
- This is interesting to note, as it was Ben himself who recreated the universe, so the mascot, logo, and taste shouldn't be different, yet for whatever reason they are different.
- The Mr. Smoothy sign in the past segment of A Jolt from the Past in Omniverse is identical to the one from Alien Force and Ultimate Alien. This is because it is at a point in time before Ben rebuilt the universe.
- However, the Universe technically encompasses not only space but also time. Therefore, Ben's changes must be applied across time, and hence in the past as well.
- Due to the fact that Ben often frequents this business and gives it his unofficial endorsement, the franchise receives a lot of publicity and will even open for him after closing time.
- In Dimension 23, Mr. Smoothies are replaced by Mr. Gyros.
- In Rex's World, Mr. Smoothies are replaced by Bob's Biscuit Barn.
- In the game, Psyphon brings Mr. Smoothy to life with a laser, and he becomes a boss. Mr. Smoothy was defeated by Ben turning into nearly all of his aliens in a row, with the exclusion being Cannonbolt.
- As Ben Battles Mr. Smoothy, marks are left behind. The following is a list of all the marks:
- Humungousaur: A very painful punch in the nose, left red mark behind
- Echo Echo: Wall of Sound (but three clones)
- Swampfire: Major burns
- Chromastone: Shoots a laser beam
- Spidermonkey: Webs (Mr. Smoothy gets annoyed and rips the webs off)
- Big Chill: Frost (two transformations later, the frost vanishes)
- Jetray: Neuroshock burns
- Brainstorm: Shoots lightning
- Goop: (goes into Mr. Smoothy's mouth and attacks from inside)
- Murk Upchuck: Drinking Mr. Smoothy
- When Psyphon beamed the laser at the Mr. Smoothy billboard, Mr. Smoothy came out but the Mr. Smoothy cup he had in his right hand disappeared.
- Also, if you pay close attention, when Ben is fighting Mr. Smoothy, the Mr. Smoothy billboard sign in the background where Psyphon beamed the laser still has the Mr. Smoothy picture on it.
- Mr. Smoothy could usually only say things smoothy related such as: 'No free refills for you!', 'Do you want one scoop or two!?' or 'Ben 10, it's time for your just desserts!'
- In the ending cutscene for Bellwood, Mr. Smoothy is much bigger than in the boss battle as it is now taller than a building.
