Mitch is a Caucasian man presumably in his 30's. He is of tall stature sporting golden hair and green eyes. His clothing attire consists of a blue, unbuttoned shirt, fedora and camera worn around the neck.
Mitch publicly presents himself as an amenable wildlife photographer and outdoors enthusiast, dressing in 20th century safari garb. He isn't an unintelligent man, genuinely knowing some knowledge in the field of paleontology enough to impress Darius Bowman, whom he formed a small bond with due to this common trait. In private however, he is a amoral and deluded sports hunter.
Unlike previous big game hunters such as Roland Tembo and Ajay Sidhu, he seems far less interested in the challenge of the hunt than he is at obtaining trophies (like the prepared head of a Sinoceratops) to decorate his "man cave". The only individual he shows any concern for is his wife Tiff, and even then, the two squabble frequently and seem to have a strained relationship. However, despite revealing his colors, Mitch remains amicable to the kids especially Darius and he even offers to take them back to the mainland as long as he and his wife have their cooperation.
He is far more patient and level-headed than his wife, as he was willing to actually help out the campers and only turned on them when they refused to help his goals, and even then found excuses to keep them alive, mostly because of their usefulness to his and Tiff’s cause. Ultimately, however, he became less and less willing to keep the kids around after they proved to be liabilities, and decided to abandon whatever moral obligation he felt for them.
At some point in his life, he met and married Tiffany, due to their shared love of hunting endangered species. The couple were hunting partners and traveled the globe hunting endangered species including lions, tigers, elephants and rhinoceroses.
Arriving to the island, the couple employed Hap as a guide. Initially the two appeared as clueless, friendly ecotourists upon finding the campers. When their true nature is exposed and Darius learns of the two being hunters, Mitch threatens him into helping the two, with either killing the group or the dinosaurs on the island; demanding Darius to take them to the watering hole. When the park systems shut down, Darius instead brings the two to Main Street.
However soon after park systems are recovered by the campers led by Brooklynn, their tablet receives power and the two give up pursuing Darius now having no use for a guide. Making their way to The Watering Hole Tiffany and her husband Mitch find themselves inside the Carnotaurus Paddock, Tiffany receives a shock from the electric fence following her unsuccessful attempt to climb out. There, he watched Tiffany shot and killed Grim the Baryonyx after almost being attacked.
Arriving at the watering hole he watched as Tiffany attempts to shoot the Velociraptor Blue but is held back by Darius and the remaining campers. Mitch and his wife Tiffany are soon forced to flee from the stampeding dinosaurs. The two are pursued by Rexy the Tyrannosaurus rex, and in the ensuing chaos Mitch becomes ensnared in his own trap. Unable to untie the knot Tiffany leaves her husband for dead, who soon after meets his death at the jaws of the Tyrannosaurus rex in revenge for sticking his cattle prod up her nose.
- Mitch is the first person to be eaten on-screen by a Tyrannosaurus on Isla Nublar since Billy Yoder or Nima Cruz from the Telltale game.
- His clothing and outfit style resembles Alan Grant from the first film.
- Like Roland Tembo he sets his sights on a Tyrannosaurus rex. Although he settles for a Doe instead of a Buck. Despite this Mitch was certainly more villainous and petty then Tembo since he hunted dinosaurs without permission from InGen and planned to abandoned the campers on the island so they not could tell anyone abaout his and Tiffanys poaching of the dinosaurs.
