トップハム・ハット卿
In the television series, The Fat Controller is always the same man, with the same wife and grandchildren. He is in his mid 60s (as evident in a newspaper article in the Great Discovery), although his voice in the UK versions sometimes hint at old age, and he has even appeared with a white moustache in certain episodes. Very little of his history is revealed, although we do see more of his extended family, including his mother (Dowager Hatt), and his mischievous twin brother (Sir Lowham Hatt). In the first season, he and all the other human characters were made out of lead. From the second season onwards, they were made out of resin so they could move around more easily.
