Everybody outs their autism in very different ways, but Lego-autists do it by actually building with it the most ofcourse. There are Waifubots and Moe-onicles and stuff, but building those actually requires some skill. Waifigs and Husbandos are easier, but often require rare parts from whole different eras if you want to do something crazy.

Last time i checked, there are minimal lego related works on r34 and the likes. But as character and theme specific things go, there are more Ninjago, Nexoknights and TLM drawings than others. But in the end it's still a very small amount compared to just how insanely popular and widespread Lego is as a phenomenon.
