!!Tropes common to IC Japan
* HeyItsThatGuy: ''VideoGame/{{MOTHER}}'' series creator ShigesatoItoi made his appearance in only four episodes.
* MissingEpisode: Due to a combination of Food Network not licensing all the episodes and no official DVD or archive of the episodes, many episodes are considered missing, including, tragically enough, a few of the specials. There is a website dedicated to finding as many of the missing episodes as possible from old VCR recordings, but per the KeepCirculatingTheTapes rules, it can't be linked.
* NoExportForYou: Most Nakamura-era and Ishinabe-era battles.

!!Tropes common to IC (Western)
* BadExportForYou: The UK version used a confusing 4 vs 1 two-round format.
** Someone described it as '[=MasterChef=] with the Iron Chef label slapped on'.
* PromotedFanboy: Michael Symon is clearly a big fan of his fellow Iron Chefs. On both ''[=ICA=]'' and ''Cook Like An Iron Chef'' he makes regular references to their habits and styles (e.g. he mentions Morimoto every time he's chopping up a lot of ingredients).

!!Tropes common to all versions
* FanNickname: Bimbo du Jour (for the younger female guests), The East German Judge (Hosoki or Kishi - whoever's in the fourth seat that day and Jeffery Steingarten in that role in ICA)
** Chairman Mark is also one, as ICA generally refers to him as just [[NoNameGiven the Chairman]], and the fanbase needs a way to differentiate between the two Chairmen.
** A bit of an in-universe example, but some of the Iron Chefs have monikers of their own: Sakai is known as "Fish Sakai" or the "Delacroix of French cuisine", Kobe's the "Prince of Pasta", and Chen is the "Szechuan Sage".
* HeyItsThatGuy: [[Series/StarTrekVoyager Seven of Nine]] was a judge!
** So was [[Series/DrQuinnMedicineWoman Dr. Quinn!]] And [[Film/KillBill Sofie Fatale]] did it in the original!
** Um, that's not the Chairman... that's [[VideoGame/WingCommander Troy "Catscratch" Carter]]!
*** Really? I thought it was [[VideoGame/DoubleDragon Jimmy Lee]].
*** You're both wrong, he's [[Series/KamenRiderDragonKnight Eubulon the Advent Master]].
''Series/HellsKitchen'' competitor Ralph Pagano shows up on ICA.
** Anthony Anderson has also shown up as a judge, as has Julie White. Even Dave Batista from WWE appeared as a judge once, where he admitted he was a big fan of the show, got served bigger portions than the others, and admitted to being rather nervous that he ends up being a judge in the episode where the secret ingredient was snails.
** And now they're crossing the network streams: [[Series/ManVFood Adam Richman]] was a judge for Marc Forgione's first battle (Battle Bell Pepper).
** As far as the chefs go, several ''Series/TopChef'' competitors have either been sous-chefs (eg. Arianne from season 5 and Ed from season 7) or competitors (eg. Spike from season 4) in ICA.
* KeepCirculatingTheTapes: Sadly, due to length/licensing issues, ''Iron Chef'' will likely never make it to DVD, leaving people to keep their old recorded tapes or search the net.
** Peculiarly enough, ditto for ''Iron Chef America'': only the Battle of the Masters is out on DVD.
** Averted in Australia: You Can Buy DVD's of the Dubbed Japanese version from SBS.
* ThePeteBest: Iron Chef Ishinabe.
** And for American audiences, Nakamura.
** In ICA, Wolfgang Puck.
