Sandy is a tough peace-loving member of MK's Team and a former soldier.
After Sandy learned about the Demon Bull King taking over the city from MK's Team, he offers them tea. However, when an enraged Pigsy learned that Sandy became a peacenik and questions him on what happened to his original self, Sandy tells him that he was told to control his anger from his therapist and agreed to help MK's Team by getting them to Flower Fruit Mountain.
However, when MK was presumably killed, Sandy and the others were devastated until Mei stated that the Demon Bull King must be defeated. When Sandy and the others returned to the city, they fought off the Bull Clones until they found out MK was alive. After MK defeated the Demon Bull King, Sandy and the others congratulated MK and celebrated by going out for noodles.
A week later, Sandy and the others were having time off at his Cargo Ship until a crate falls on MK. However, MK reveals that he's alright due to being invincible. After Mei says that every hero should have a headquarters, she takes Sandy and the others inside the Cargo Ship to show them their new secret base, the Sea-Crate HQ. When Tang questions Sandy that wasn't he building a headquarters for MK as well, Sandy lies by saying no to prevent anyone from knowing.
When Sandy and the others notices that Red Son was taking control of the Weather Station, they head out to the Weather Station to stop him. However, due to MK still not having complete control of his powers, he accidentally injures Sandy and Mei, letting Red Son and the Bull Clones capture MK's Team. Eventually, after the Monkey King limited MK's powers, the latter was able to defeat Red Son and the Bull Clones as well as free Sandy and the others.
At the Sea-Crate HQ, Sandy and Mei were inside discussing if they even need a headquarters until MK comes in to tell Sandy and Mei that Pigsy is missing. When Mei checks the camera she installed in Tang, Sandy watches what happened and realizes that Pigsy and Tang were kidnapped by the Spider Queen.
Later, Sandy and the others ventured across the Silken Web Cave by using his speedboat to rescue Pigsy and Tang, but only for them to get ambushed by the Spider Queen. However, when Mei dropped the Dragon Blade when she was caught, Pigsy and Tang were able to use the blade to free themselves and the others to rescue MK, who was being chased by the Spider Queen.
After MK's Team confronted the Spider Queen, Sandy and the others attempt to rescue MK but only for the Spider Queen to attack MK again, but only for her to cause a giant hole instead, causing Sandy and the others to fall down until he gets an idea to rescue the others by using his Speedboat and escaping from the Spider Queen.
Sandy is a big blue giant with and orange beard and mohawk. He wears a magenta pearl necklace as well as white track pants and white running shoes.
