Despite the villain image of Dokuta Egguman, he is actually an old urchin with a good sense of humor, romance, narcissism and childishness. This seems to stem from the fact that several actors who voiced him have such a personality (although several have passed away). And he's very gentlemanly-though it's hard to tell from his appearance.

For his family, Dokuta Egguman respects his grandfather Professor Gerald and is determined to be like his grandfather. He hopes to make intelligent robots like his grandfather, but he will only turn them into fighting weapons every time.

What Dokuta Egguman hates most is naturally that Sonik and others sabotage his plans, but he has never looked down on these positive roles. Many machines he made imitated the characteristics of his opponents. In addition, he likes Tals very much, and Tals has the same high IQ, but Dokuta Egguman never allows anyone to surpass his invention.
