EraserDeku

Dekuhead is the SLASH ship between Izuku Midoriya and Aizawa Shouta from the My Hero Academia fandom.

Canon
Izuku Midoriya goes to UA Highschool, his main  homeroom teacher  being Shouta Aizawa. At first Shouta had his doubts about Izuku passing the Hero course, but after seeing him channel his power and eventually have complete control over One for All.

Fanon
People definitely ship this, and it's disgusting. Its a pedophilic ship, just like Starker from the MCU Fandom. This paints Shouta Aizawa as a gross pedophile, it's something nobody should be shipping. It doesn't have a lot of popularity, thankfully, but the small majority who do probably live in hiding on Discord. Seriously this stuff is not okay.

Trivia

 * Their ship name is a mashup of their hero names: Deku and EraserHead.
