Yeah, this is the first really big fight that the Parasite's been in ever since both the Unity and Lex Luthor upgraded him into Parasite 3.0.
That's why he's not having mental problems any more, why his white stripes and circular mouth are gone, and why he's smarter.
And as for the whole "shoot girders and anything else that's handy at Rudy routine," I'm seriously trying to avoid doing the blatantly obvious and have the Parasite just simply absorb the inertia of whatever's being shot at him. The baseball thing with Hal and Kyle is fine, but just shooting multiple girders at him, without giving me time to respond, and then moving onto a completely new form of assault by multiple opponents simultaneously, uhh... okaaay...
This is like the time that Batman tried to physically take on the Parasite and I had to bite my lip and try not to laugh and instantly zap Batman into dust just by being within a few feet of the character, which was forcing me to disregard what my character can and would do.
I realize that the Parasite is a difficult opponent to face, but his defeat is not Kyle, J'onn, Hal, or Sinestro's responsibility. It's already been planned out, and it only occurs after his current fight is complete and he takes on Superman. It's perfectly fine if you guys tire him out a little bit in this scuffle, I have zero problem with that, but note that he is not going to be beaten in the current fight.
