About: We don't know much about Dex, except that his obsessive behavior makes the men he's set his sights on feel uneasy. He has a tendency to say it's passion, and not obsession, that drives him. Non-stop complaints from the people he's followed everywhere regularly get put him behind bars. But he always finds a way out...
Dex wearing the same villain outfit as Dabi, and being villainous as well, though not as destructive and cruel like Dabi. Dex is also shown using Dabi's power, the Quirk called Blueflame, which as its name suggests, produce fires that are blue in color. Most of Dex's poses are referencing various anime concept arts of Dabi, and the 4-star pose is a reference to My Hero Academia's Volume 30 cover.
