Onslaught behind the floor...

[Tiger-Boy]

Now that Onslaught by Sludge is out, I still have a thing for the fact that in his giant form, his body is in front of the floor. I know it may be a small detail to some, but the same thing happens with the Apocalipse char, and he has a floor already in front of him. Is there a way to copy this process, or to edit a certain stage to make Onslaught's body get behind the floor?

Thanks in advanced!
