Where are Abomination and the Leader?

Since we mentioned these two, the first point can be this one: what happened to all those characters from the Incredible Hulk? Quite a few times, the MCU has brought back secondary characters from the solo movies in subsequent installments. For example, Peggy Carter still appears in the Captain America series (as well as in some others). Erik Selvig has popped up in both of the Thor movies, as well as in both of the Avengers flicks. Even Coulson got the chance to appear in quite a few solo flicks, until his untimely death in the first Avengers.
We always knew that The Incredible Hulk was like an outsider movie that somehow managed to make its way into the MCU.  But this year the Civil War will show that it is indeed one of the recognized movies of the shared universe – General Ross will be brought back, being one of the men behind the Sokovia Accords.
If he’s back, there are a couple of questions we could ask that the silver screen movies of the MCUÂ haven’t answered, including these: Where is Abomination? Where is the Leader? And where is Betty Ross?
As far as the latter is concerned, knowing her past relationship with Bruce Banner, it is inexplicable how she hasn’t appeared again thus far. Pepper Potts did on a number of occasions, and so did Jane Foster and Peggy Carter. Can’t the big guy catch a break?!?
