Mordecai is a prize-winning hog from Arline, Kansas who came to the Chan's attention when he was featured in the local newspaper after winning a blue ribbon at a county fair. Jackie and Jade attempted to buy Mordecai off his owner, Farmer McDonald, who refused because of Mordecai's abilities and because he deeper mistrusts "city folk". Jackie attempts to take Mordecai by sneaking to his sty at night, but fails to budge the large pig. Jackie then tries to carry Mordecai which causes him to activate his heat beam eyes out of fear. This prompts the fellow noble animal Eggbert to crow and wake up Farmer McDonald along with his two farm hands. After Eggbert is released from his cage, he meets up with Mordecai and the two proceed to take spree around town with Eggbert using his Rooster Talisman powers to levitate Mordecai as he sits on top of him, creating a literal flying pig. After raiding a pet store to feed, Eggbert and Mordecai then start rampaging before Farmer MacDonald takes both animals for himself. Daolon Wong then arrives and, despite the Chan's best efforts, he manages absorb the powers from both animals. Mordecai and Eggbert then live together on MacDonald's farm.
Then in season 4, Mordecai, Eggbert, Super Moose, and Jade all go against Jade's dog Scruffy, possessed by an Oni mask, and help have the mask taken off and releasing Scruffy from it's hold. Eggbert and Mordecai were both being powered by the newly made Rooster and Pig talismans, respectively.
Mordecai appears again in the series finale, helping the J-Team and the T-Troop, (the name of the team of Super Moose, Eggbert, T-Girl/Jade, and Mordecai), defeat Drago.
- In Re-Enter the Dragon, Jade picks up a random pig from a zoo and aims it at Shendu, confusing the pig with Mordecai. Jade likely did this out of panic, as she'd witnessed Shendu steal the powers of levitation and heat vision from Dalong Wong shortly after Dalong Wong resurrected Shendu that same night to try to get the power of Combustion (power of the Dragon talisman), although Shendu double-crossed him and took that power for himself also.
- Mordecai can be briefly seen at the end of Black and White and Chi All Over when attending Jade's birthday party. This indicates that Mordecai and Eggbert are rather close to Jade.
- Mordecai is a 280lb Hampshire boar and is aged 2 years old by the time of his first appearance.
