This Comic's Cast:

There is a difference, though. I do feel nerdy writing this, but:
Elastic Man (aka the Elongated Man) can stretch and contort his limbs to extreme lengths, although he does have limits to how far he can bend and stretch (as per the finite amount of natural mass to his body.
Plastic Man can stretch and contort as he sees fit, making himself into just about any shape he wants.
Both are DC characters, though, so it's not as if there's a trademark issue.
And, of course, Batman could beat them both. Batman is just that good.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
