Kahhori and Byrdie are playing foosball where the players are figures of the following popular Marvel characters: Kahhori's hero team: Captain America (goalie), Iron Fist and Luke Cage (defenders), Wolverine, Scarlet Witch, Invisible Woman, Black Panther, and She-Hulk (midfielders), and Beta Ray Bill, Iron Man, and Rogue (strikers). Byrdie's villain team: Galactus (goalie), Ultron and Magneto (defenders), Mystique, Loki, Dr.Doom, Hela, and Baron Zemo (midfielders), and Kang, Thanos, and Red Skull (strikers).
Iron Fist and Luke Cage are positioned on the foosball table as defenders. Both were members of the Defenders in the comics, as well as in the 2017 Netflix series, The Defenders.
This marks the first MCU appearance of the following Marvel characters: the Almighty Storm (Goddess of Thunder), and Byrdie (created for this show just as Kahhori was in season 2). Other characters having their first appearance in the MCU include the following, whose images are used as players on a foosball table: Galactus, Magneto, Rogue, Mystique, Dr. Doom, Invisible Woman. The other foosball players have already appeared in MCU movies and/or shows.
Mystique is placed as a member of the villain team on the foosball table which could hint at her reintroduction in a live action MCU role. In the comics and previous X-men movies, she has been both a villain and a hero (or anti-hero).
