While DC universe has always been into the multiverse scenes and always eager to mash them together, it seems that Marvel universe has done it before DC. They brought in their 2 previous versions of Spiderman together. Another mash up would probably be some out of the screen events. Disney Marvel has brought in the Netflix Marvel Daredevil character for a brief cameo. Matt Murdock will show up for a short scene. All these while Disney have always separate other Marvel characters that they doesn't use in their movies. It was a surprise that they put in the Netflix's Daredevil character for a short cameo.
