No, you can get both. I see what I wrote there, d'oh. If Vicks is when you when you claim the reward, you get the Paradigm. You can still defeat it with Cid and Reeve and claim the reward after the party reunites.
This is one of my favorite battles in the game so far. Being that he's a zombie and is called Still Going, he is passively under Fury status and he will constantly revive with Reraise randomly up to five times, lol.
He can also inflict Curse, Zombie, and Disease status with his abilities, and when he activates Growing Threat (which all Mission Marks do) he starts using some nasty physical attacks.
