Here is my take on hydroman, as I don't think Hasbro will be producing another hydroman anytime soon. The recipe is as follows

The base body is Scott Steiner from the TNA series with sculpted bottoms for his trousers
The head is HML Banshee
The water effect arms are small bits of clear rubber hose covered in hot glue. They are easy to fit over his hands but as the hands are removeable I prefer to put them on his lower arms.
Other than that the hands, blade, hammer and wrecking ball all come from a Spiderman 3 sandman. It isnt shown on the pictures but I superglued the ends of the sandmans arms to the rubber hose so the parts are all interchangeable.

The only thing left to do was paint the figure - chaos black for the t shirt and also the base coat for the trousers. I then drybrushed iced blue over the trousers a few times till I was happy.

The arms were fun to do using a mixture of painting and drybrushing iced blue, white and then a combination of the two colours to lighten up some areas

I am over the moon as to how it has came out and I hope you like it as well

Any comments are always welcome. Now I will start work on that base for him
