Oh wow, is that a new 52 scan of Adam? Looks pretty awesome...
1 to BA I think. Adam should be too much for Thor to handle without mjolnir.
With Mjolnir then I think Thor can take the other two.
Now I usually end up using Adam as he appeared in WWIII, so I may have a slightly skewed view of his abilites overall, which I wuld be open to adjusting...
