Previous Post I'm not sure how I feel about the show. I seen a few episodes & I'm not sure how I feel about the show. There are things I liked about the show (like as you mentioned the references to the wider MU) but then there was stuff I don't like (The art style among other things). I will say this It's better then the Super Hero Squad show & the old '90's Avengers cartoon (which I kind of liked but knew it was bad).

According to Wikipedia:

Disney XD is a brand of children's TV channels worldwide targeting young males,[1] owned by The Walt Disney Company. The channel was formerly known as Toon Disney and/or Jetix in most areas. According to Gary Marsh, President of Entertainment for Disney Channel Worldwide, "XD" does not "stand for anything" and was chosen simply because it looked "cool". Marsh notes that "the letter X has many cool associations" and that "the beauty of it is the audience can imbue it with all sorts of positive attributes."[2] The "XD" in the Disney XD logo is written in the Exablock font, even though the font made its official debut a couple months after the channel's US launch.

So apparently it doesn't mean anything at all.

I saw that Avengers show while in Florida a few weeks ago. It was ok, but nothing that made me rush to add it to the DVR.
