|“||Are we sure he's a vampire? I mean not that it's a bad thing, but shouldn't he have fangs and that pasty skin you guys have?||”|
— Linda questioning whether Dennis is a vampire or not.
Michael "Mike" and Linda Loughran are Jonathan's parents. They appeared in Hotel Transylvania 2. Mike is voiced by Nick Offerman and his wife Linda was voiced by Megan Mullally. Linda is funny, hilarious, clumsy, goofy and hyperactive. Mike is grumpy, cranky, smart-mouthed, ill-tempered and intelligent.
After Dennis was born, they both became concerned for his well-being and morals. Though they mean well, they end up accidentally insulting Dracula and Mavis. Primary example is when Johnny and Mavis came to visit and they made a makeshift coffin for her to sleep in.
They later show up to attend Dennis' fifth birthday dressed up as Zombies to hide their human identity from Vlad. After Johnny reveals that he is a human to Vlad, Mike and the rest of the family stands up to Vlad by removing their costume makeup and revealing they are human too.
Later, the two of them a long with everyone else journey into the nearby forest to look for Dennis after he ran away. The two of them and help in fighting off Bela's army.
They are last seen attending and dancing at Dennis' fifth birthday party.
Linda is the happy and perky wife of Mike. She is also nice to Mavis when she and Jonathan first arrive in California by giving Mavis a new sunhat to wear to protect her from the sun, and even invites over some other monster/human couples to make Mavis and Johnny feel better. Unknown to her that it makes Mavis feel uncomfortable.
When Vlad comments that Mike and Linda smell funny, Linda just assures him that it's because he's European and doesn't know what deodorant is. Her husband Mike sighs at this comment, sounding annoyed as he comments back "Nothing like insulting an entire continent, Linda."
Mike is the grumpy but caring husband of Linda. Like his sons, he's ginger. Mike doesn't seem to mind the Monster culture as much as his wife, Linda. For most of the film he is perfectly fine with the monster lifestyle and does his best to respect it. However, he does seem to not like Dracula that much at first. He's annoyed at how Dracula calls his grandson, Dennis, Denisovich. He also thinks that Dennis should move to Santa Cruz with him and the rest of the family where he'd be more safe and accepted since Dennis shows more signs of being a human rather than vampire.
