Dr. Thomas James aka Drill Finger is a recurring antagonist on the TV show Henry Danger. He is a mad dentist who enjoys ruining people's teeth. He was first mentioned in the episode "Substitute Teacher", and a supporting antagonist of later episodes "Danger & Thunder" and "Double Date Danger".
3 years ago (prior to the events of Substitute Teacher) he took all the teeth out of the mayor's mouth. He was later arrested by Captain Man; as he was taken away he vowed to "Take care of Captain Man". After 3 weeks past, he was released from jail and was in Nebraska dumping megatons of sugar into the water supply to give people cavities (the action was done offscreen); meanwhile Captain Man, Kid Danger and Charlotte Page were dealing with mistaking the new student Ortho and his father as the supposed son of Drill Finger and the villain himself.
In Danger & Thunder, he was one of the villains present in the meeting the Toddler had made about destroying Captain Man, and his sidekick Kid Danger. When trying to figure out who called the meeting, Drill Finger guessed the The Three Muchachos. He disappeared when Man had broken the lights of the lair.
Avoiding capture, Drill Finger returns in Double Date Danger to help Noelle pull out Jasper Dunlop, Piper Hart and Kale's teeth. He was defeated by Captain Man and Kid Danger when Captain Man broke his "drill finger" and started calling him "Finger", which he complains isn't as good a name. He was then taken to jail.
- Though not proven, he may be the very one that gave the Phone Shark his sharp metal teeth.
- He is 6'2" and weighs 185 pounds.
- While his mugshot in Substitute Teacher shows him with perfect hands, in Danger & Thunder, he is given a drill on his left index finger.
- Drill Finger and Jeff are the only villains who make an appearance in the Henry Danger: Motion Comics.
- Noelle might be Drill Finger's daughter.
- His name might be a reference to Auric "Goldfinger", a villain from the James Bond film respectively titled Goldfinger.
- He may be wearing a mask because of a past accident or he may be hiding his true identity.
- If Noelle is Drill Finger's daughter, he's likely Sharona Shapen's brother. However, due to his last name being James, it's likely he's Sharona's step/half brother.
- In the cartoons, his mouth and eyes are visible and his mouth can move.
- Since Captain Man broke of Drill Finger's finger drill, it's likely he won't make another appearance.
