Frankenlady is one of the new characters set to appear in Hotel Transylvania 3.
Frankenlady is Frank's cousin... from his right hand's side. Literally. In the film, she is set up with Drac during a wedding dance, and things seem to go well. Until Drac is put off by her freakishly strong, and big, right arm. Luckily during a quick dance, Drac pulls away, but leaves Frankenlady wanting more.
