Avengero  Suggeriti da moviefan2k4 

The main logos all seem to be custom jobs, done by Marvel. That said, there's several fonts which get pretty close. I came across a recent one maybe a week ago, created last year. Its called Avengero, available at a website called FontStruct. The creator of that typeface also did a variety called Avengero Disassembled, where the letters look like they're dissolving.
