I received this set together with 0217 - 0222. I think you would never want to scroll too far down so I separate review for both of the set.
Name of the characters printed on the box:
0223 - Nick Fury
0224 - Vision
0225 - Maria Hill
0226 - Baron Von Strucker
0227 - Iron Legion
0228 - Ultimate Ultron
Catalog and trading/game cards from this set and Decool 0217-0222:
Catalog provided in each box.
Assembled minifigures:
Forgive me for not taking pictures of every minifigures with their accessories and weapons. Here is a picture of the extra parts/accessories/weapons (from this set and Decool 0217-0222).
Each minifigure comes with a super jumper. Super jumper in the picture below is from 2 sets. 0217-0222 and 0223 - 0228.
Comparison with original Lego figure on right.
I'm sorry for the inconvenience below. I do not have the original figure for Nick Fury and Maria Hill. Therefore, I have photoshop image from bricklink and put it in my photos. As far as i can remember, I always put the original lego figure on the right when i do the comparison but there was a mix-up in the following images:
I almost forgot to mention that Maria Hill from Decool has the same curved waist on the torso, similar to Supergirl from Decool 0200.
Is it correct to say this marked the end of the imitation for Avengers 2 AOU Lego figure? So far we've seen these characters have been copied by Sheng Yuan, Dargo and Duo Le Pin:
Sheng Yuan - SY275 & SY276
Sheng Yuan - SY271
Duo Le Pin - DLP9005
Dargo - No.852
Decool - 0217-0222
Enough with the AOU. There are many more new sets produced by Lego recently. hehe. please... no more AOU figure ya >_<.

I feel really lucky and grateful to @JC for his help with list of other China brands that also produced these AOU figure. Here is the information that has been submitted by him through the comment section. Thanks @JC :)
About the other imitation AOU figures, I actually got obsessed about it last week and made some research. There are actually1112 brands that made AOU figures! It's insane! I'm not gonna post the pictures, but I'll include the links. And basically, SY & Decool are the only sets that are good. The other 9 brands are not good even on pictures.
Bootleg brands:
1. Decool
2. Sheng Yuan
3. Duo Le Pin
4. Dargo - they still have some upcoming AOU figures. You can see them on that picture with the 47 figures they're releasing
