TamaWall

TamaWall is the cargo ship between Tamaki Amajiki and the wall from the My Hero Academia fandom.

Canon
When we are first introduced to Tamaki, he is visiting Class 1-A to discuss work studies. Mr. Aizawa requests that he introduce himself and, after trying to imagine the students as potatoes to calm his nerves, he immediately turns around and presses his head against the wall. The students later move to the gym so that Mirio Togata can show off his Quirk and, again, Tamaki is seen with his head presses against the wall.

In season four we get to see Tamaki in action while on a mission with Eijiro Kirishima and Fat Gum. Although it is clear that he's an incredibly strong hero, his self-esteem is still rather low. When one of the villains calls him "Chicken Foot", he reacts by immediately finding the nearest wall and pressing his forehead against it.

In the "Hero League Baseball" OVA, Tamaki is put in the position of an out-fielder. Partway through the game, he is seen with his head pressed against the stadium wall, muttering about how he wants to go home.

Fanon
TamaWall is a crackship and, as such, does not have very much in the way of fandom works. Much of the TamaWall content comes from joke videos on YouTube or TikTok, or joke posts on sites like Tumblr or Reddit. Still, many people appreciate the running gag of Tamaki always putting his head up against walls. Cosplayers even utilizes the joke when dressing up as Tamaki.
