- Antonov is the second host to not have evil intentions for the tournament, the first being Chizuru Kagura.
- The two characters also are the only sub-bosses who returns in a regular team in future KOF games.
- However, unlike Chizuru, he didn't have any kind of a hidden agenda behind him hosting a KOF tournament.
- The game's composers shout his name during his Type-2 theme song and Antonov himself proclaims "I am the King of Fighters!" in the intro of the theme song, as well as saying "Thank you!" and "Okay, one more!" near the end before looping.
- The other version of his theme, Type-1, doesn't have this sayings, playing only the instrumental version.
- The exclusive theme in The King of Fighters XV, "I Was THE KING OF FIGHTERS", is based on Type-2 of his song in KOF XIV.
- All the music themes of Antonov are sung by his voice actor, Moriyuki Hishida.
- Antonov is likely based on WWE American wrestler Triple H (alias of Paul Michael Levesque).
- His redesign for The King of Fighters XV is likely inspired on late WWE American wrestler Randy Savage (alias of Randall Mario Poffo).
- His story concept is based on the story of Mr. Satan, from the Dragon Ball series.
- Antonov and King of Dinosaurs are the only characters in the series to break physically the fourth wall.
- The other character to use the feature in the series is Yuri Sakazaki: in her win pose against Gai Tendo in KOF XI, she suggests he try saying "Hurricane Upper!", referencing the fact that Gai and Joe Higashi have the same voice actor (that voices Joe until KOF XIII and Gai until KOF XI).
- The Samurai Shodown series also uses the break of the fourth wall with the characters Yoshitora Tokugawa (during his fatefull battle with Jubei Yagyu [another fourth wall breaker] in Samurai Shodown (2019), he looks to the player), Wan-Fu and Iroha.
