Dr. Applecheek is the quaternary antagonist in Tom and Jerry: The Movie. He has two henchmen, who are straycatchers that catch animals and bring them to their boss. The late Henry Gibson did his voice.
At first glance, Dr. Applecheeks is a sweet, dignified, reasonable, protective, affectionate, patient, positive, loyal, even-tempered, caring, humble, empathetic, extroverted, kind-hearted and selfless pet owner who keeps animals in his house but turns out to be an evil, dramatic, relentless, pushy, arrogant, pompous, prissy, loquacious, emotional, clever, harsh, egotistical, eager, kinky and sneaky doctor who keeps animals in prison (Even if he has to kidnap them) in his secret cells and sells them for ransom to rich people. Figg had paid him to euthanize Tom and Jerry.
Jerry activates all the switches to free Tom, Puggsy, Frankie DaFlea, and all the animals from their cells while all the other animals escape from the clutches of Dr. Applecheeks. He then blames this incident on Aunt Figg who denies it at first but is willing to take the blame after Kiddie informs her that he found Robyn.
When Dr. Applecheeks overhears about Aunt Figg's $1,000,000 reward at Capt. Kiddie's carnival, he attempts to find Robyn before Aunt Figg does. However, he is dropped off by his own henchmen when he refuses to split the reward with them and is almost being run over by Lickboot. Then, Dr. Applecheeks spots an ice cream vehicle and steals it in order to continue the chase while leaving the two henchmen trapped on Kiddie's Ferris wheel. Dr. Applecheek then crashed into the river onto Kiddie and Squawk due to the bridge been destroyed by Ferdinand and was never seen again. It is presumed that he was arrested by Robyn's father for his involvement in the one million dollar bounty reward on Robyn, and returned the ice cream vehicle back to its owner.
