I've thought a lot about super bosses. a giant boss coming up from the ground (not all the way) and having a limited circle to move around him (if you get knocked away too far, you fall into blue super lava).
he would have a giant hammer that he smashes down frequently, but eventually his hammer gets stuck. That is when you climb up to hit him once, getting knocked back and having to do it all over again (he gets more frequent every time you hit him). the giant dies in a cool way the 3 and final time he gets hit, exploding and sinking into the blue super lava.
