One of the more interesting facets of Minifigure collecting are civilian identities, the thing being that many are just ordinary blokes and where you draw the line. Not many have come out officially, just the likes of Peter Parker and Clarke Kent before the Lego Batman Movie put a few more on the table. Bruce Banner hasn't been one of them however, despite a prominent role as himself in the Avengers movies rather than just being the Hulk the whole time.
This Minifigure therefore appears to be another Chinese copy of a custom figure, the fun thing being that Bruce is depicted mid-transfomartion, with one arm, half of the torso and the corresponding leg just starting to go green and rip through his clothes (though the tear on his trousers is basically at his crotch, which could make for an interesting change). Further adding to it is a grimacing face (which can be turned for a more neutral look, though as the rest of the figure can't be changed this seems a bit pointless) and a syringe, presumably after just injecting himself with the Hulk serum.
The look seems to be modelled on the Mark Ruffalo version, which is a shame - a nice pair of specs for that classic Bruce look would have been nice. The other thing is that it could really do with there being a fully civilian version to model the transformation with this as a middle stage but it does the job it sets out to do nicely.
