Frankenstein is Eunice's husband and one of Dracula's best friends who acts as an uncle to Mavis.
Frank has light blue skin, green eyes, and black hair. He wears a blue suit with a white stripped shirt, red tie, and black boots. Comparing with humans, his limbs are relatively large.
Frankenstein is friendly, easygoing, kind, lovable, gentle but also uncontrollable sometimes. Generally, Frankenstein, or Frank to his friends, has an easygoing personality and gets along well with the others. His one outstanding quirk is his stereotypical fear of fire. Even a lit match is enough to send him out of control in a panic. His pyrophobia is so great, that he refuses to travel by plane and sends his body parts and that of his wife Eunice through the mail. The reason for this is that he's scared that the plane's engines might catch on fire.
When Dracula married Martha, Frank along with Murray, Wayne, & Griffin the Invisible Man play music for them. When Martha gave birth to Mavis, he cried & blew his nose on Murray much to his annoyance. After Martha was killed & Dracula's house was burned by humans, Dracula lived alone with Mavis & built a hotel for monsters to be safe.
Arriving at the Hotel
Years later, in 2012, Frank along with his wife Eunice arrived at the Hotel by postal shipping to attend Mavis' 118th Birthday. When the Werewolf Kids knocked the Zombies, his head came out and was greeted by Dracula. When Murray arrived, he made fun of Frank's weight which leads Frank into moving his legs and let out a terrible gas-passing framing Murray.
He and Eunice went up to Mavis's room to greet her. When Mavis tells them that Dracula is letting her go to a human village, they were shocked as they still believed they're violent, But Mavis suggested that they might have changed. When everyone tells her to be safe, Frank supported the idea of Dracula allowing Mavis the freedom to see the outside world, but whispers to watch out for fire. After Mavis flies to the human village, Frank praises Dracula of how proud he was for letting Mavis go, but he discovered that Dracula was gone not knowing that the village was Dracula's plan to make Mavis believe that humans are bad.
After Dracula returned & discovered that his plan lead a human named, Johnny into the Hotel, Frank spotted Dracula, wanting to ask how Mavis' visit to the village was, but he was unable to find him when Dracula hid behind some luggages.
When Dracula was trying to get Johnny out of the hotel with his secret exits, he sees Murray, Frank & Wayne fighting Zombie Mozart, Bach andBeethoven after the zombies wouldn't let them sing for Mavis' party. Frank saw Dracula & ask what he's been doing, but Dracula wants to know what they've been doing first. After hearing the reason of their fighting with the zombies, Dracula orders them to put down the Zombies. Frank and the group tried to convince Dracula to sing with them, Dracula tells them that he hasn't sang since Martha's death. Frank tried to push Dracula some more to make him sing knowing that Mavis would love it, but Dracula scares them when he explodes with anger, "I said NO! Don't ask me again!" he said. When Johnny got out of the secret entrance, Frank stomps towards Johnny as Dracula protects him & Frank demands to know who he was. Johnny acts like Frankenstein, who Frank though he was making fun of him, but Mavis tells him he was his cousin, "Johnnystein" after meeting him. But Frank was confused knowing that he doesn't have a cousin, but Dracula & Johnny made him believed it & that Johnny was his right arm's cousin. Frank greets Johnny shacking hands & lifting him up & down. Continuing the lie of being a party planner, Johnny decides to see how good Drac's friends are; he finds their musical talent "good, but a little old school." Borrowing Murray's guitar, Johnny improvises a rock song for Mavis, impressing her and the crowd; everyone wants Johnny to help with something, but Dracula says they have to stay on schedule. Annoying Drac, everyone wants Johnny to join in.
The first activity was bingo & everyone except Dracula was bored. He participated in a game of charades in the auditorium. The game is inturrupted, however, when Johnny shows off his scooter. At the pool, when everyone particapated in a game of "Chicken Fight", Frank jumps off of the Giant Octopus' tentacles to dive into the pool, resulting in letting his parts come off.
After Johnny was kicking out of the hotel by Dracula, Frank relaxes in the Sauna with the monsters. He admires of Johnny, and that he enjoyed seeing Mavis spending time with him but Dracula said that she would be with someone of his kind. When hearing this, he think that Dracula is saying no one's kind is good enough for him & gets mad. Dracula tells everyone that Johnny left & lies that he didn't like Mavis & all the monsters. But Johnny fell from a weak part of the roof landing on Dracula after showing Mavis her first sunrise. Frank thinks that Johnny had second thoughts.
Learning The Truth
On the night of Mavis' birthday party, Frank along with, Murray, Wayne & Griffin sang & played music. After Dracula had an argument with Mavis after seeing that he thought that Johnny kissed Mavis, he yells out that the village that Mavis went didn't exist. Hearing all this, Frank demanded to know what he did & Dracula revealed that he built the town she visited the night before to scare her into staying at the hotel. To make things worst, the chief of the hotel, Quasimodo arrived along with his pet rat, Esmeralda to tell everyone about everything, but was frozen by Dracula earlier, but The Fly speaks frozen & tells everyone that he said that Dracula brought a human into the hotel & that the human was Johnny. Frank still believes that Johnny was his right arm's cousin & that Quasimodo was lying, but after Esmeralda reveals Johnny's identity, Frank was shocked by this as everyone panics. When Johnny rejects Mavis for Dracula's respect, lies that he hates monsters, & Mavis blamed Dracula for everything & flies away. Frank & Euncie gave Dracula a dirty look & gets in their boxes to leave the hotel.
Getting Johnny Back
When everyone was trying to check out of the hotel, Murray was trying to mail the Steins. When Dracula arrives at the lobby, he apologizes for lying, telling them that Johnny wasn't bad & that he think that humans aren't bad anymore. Frank comes out of the box saying that he really liked Johnny, & that he told fun stories if he's his cousin or not. When hearing from Dracula that Mavis & Johnny zinged & that he got in the way, Frank started to cry stating the you only Zing once in your life while he was short circuiting, but doesn't care, so He, Murray, Griffin, Frankenstien and Dracula rush to find Johnny. With the help of Winnie smelling Johnny's shirt, it was revealed that Johnny was at the Airport leaving at 8:00am. Dracula and the group were confused when they arrive at the town where they are greeted by the humans & by a sign advertising a "Monster Festival"; they are shocked to find humans dressed up as monsters and several banners with pun-related cheers for them. Unfortunately, the way to the airport is blocked, so they walked through the crowd. Frank gives Dracula a hat to protect him from the sun. Murray gets an idea to show everyone who they really are, but sense they haven't scared anyone in years, Frank forgot how to scare people.
Griffin uses Frank's pyrophobia to try scaring the humans; however, they cheer as they idolize the monsters. Frank yells that he's trying to scare them, & that he's real, but everyone knows & loves him. Frank shows everyone the real Dracula & explains the situation, so several humans dressed as vampires uses their capes to provide shade for Dracula all the way to the airport.
After Dracula got Mavis & Johnny back together, Frank was seen along with Eunice, celebrating Mavis & Johnny's relationship & He, Mavis, Johnny, Wayne & Murray, even Dracula sang a song about Zing.
Frank goes to the D.J. booth and scratches Wayne's stomach like a record then Wayne is last seen dancing on the flying tables.
