I shouldn't consider members of the Legion of Substitute Heroes as candidates for "Bad Costumes", because the whole point of the group was to get laughs. But I dare you -- nay, I double dog dare you! -- to look at this costume for "Chlorophyll Kid" and not make some sort of "He's got wood!" joke:

I know I'm going out on a limb here, barking up the wrong tree. And I ought to stem the tide of bad jokes, and just leaf him alone.I'd go on in this vein forever, without having to branch out too far, but UGO would probably make me petal my bad puns elsewhere if I did. And so I will quit in the full flower of my mockery, without being a complete sap, packing my trunk for home. I'll give you a ring or two before long, from the safety of my arbor, and hope I get you on the vine. Line. Whichever.

funny puns
Hey Jeff, I noticed most of your bad super hero costumes seem to come from the same publisher. With the super hero in front and random red inking in the background, am I right or are my eyes deceving me. Wood (haha) you please tell me if I’m right in my theory?

Most of the images are from either “Who’s Who in the DC Universe” or “The Official Handbook of the Marvel Universe”, both of which are collections of every significant player in those universes at the time of publishing. The DC set features really nice illustrations, both in the background and for the main figure, and that’s what you’re noticing Ashton.
Others (like the original one, Truk) are from back issues I happen to have lying around, but the collections are just so darn useful, I mostly pull from there.
