Can I customize and upgrade my characters in Sonic?

In the context of Sonic, customization and upgrades are features primarily found in specific Sonic video games rather than at Sonic Drive-In restaurants. In video games such as "Sonic Forces" and "Sonic Colors: Ultimate," players have the ability to customize their characters by altering their appearance and abilities, adding a unique personal touch to the game experience. Players can unlock various items, costumes, and abilities through gameplay progression or special challenges. However, when it comes to the food offerings at Sonic Drive-In, customization is more about personalizing menu items. For example, customers can often specify toppings, flavors, or modifications to their meals, such as altering burger toppings or slush flavors. To explore the full range of food customization available, visiting the official Sonic Drive-In website might prove helpful.
