Barry Allen (Earth-90)

The Flash is a speedster from earth ninety.

After an intense battle, the flash is seen dragging himself towards a giant book that glowed with purple energy. Before he could reach it, it was picked up by a very imposing figure in armor. When the speedster asked why he was doing this the figure said that they had done this to themselves, and now they will perish, he then opened the book while the flash ran off to parts unknown.
