- In the second series anime only, this monster is supposed to be the embodiment of Mako Tsunami's father, indicating that the "The Legendary Fisherman" looks similar to him.
- This monster appears in the artwork of "Sea Stealth Attack".
- The idea behind this card's effect is likely that "The Legendary Fisherman" hides beneath the waters of "Umi", which protect it from attacks and Spell effects, but hiding below the water's surface also keeps it from protecting the player.
- This card's design may be inspired by a real man named Filomeno Patacsil, a Hawaiian fisherman who, in 1957, rode an 800-pound Tiger Shark in an attempt to free it from one of his fishing nets. Furthermore, in Hawaiian culture, sharks are highly respected creatures which may explain the normally odd combination of the fisherman himself and the shark he rides in this card's artwork.
- In the manga, this card was a level 4 monster rather than a level 5 monster.
