Detolf's have 15" of clearance per shelf and Groot's 15.35", so he will need to do the head leaning thing or crouch to fit. Personally I would mod the height of the shelves (just using those U screws w/bolts) since I think he needs a bit of head room to breathe and some poses (e.g., glowing hand) will look best with him able to stretch his arm up past his head.
