The Silver Age was Glorious in an Odd Way

Arsenal, Lightning Lad and Ultra Boy with a little.... extra something to them. XD

As pointed out to me when bringing up the idea of drawing this, this actually happened in the Silver Age, though not to these three, rather to Matter-Eater Lad.
I've been looking for an excuse to draw Arsenal and Lightning Lad for a while (because apparently I need an excuse to draw) so this little idea was very much welcomed.
You'll also notice there's a bit of a difference to the colouring on each figure.
...Moving on.
Haha! Legs? What are those?
