Personally, I'd completely cut out the "come back to life" part of Manhunter Grandmaster; I know people we're arguing for it for thematic reasons, but I don't like it on there because: 1) it's a lot of text that takes up a lot of space, 2) it adds a third (and complex) mechanic to a single power which it doesn't even seem to fit into (the first two parts of Manhunter Grandmaster interact with the Manhunting power; this part doesn't at all), 3) it makes a tough unit even tougher, making him arguably annoying to face.
Even without that part he'd be a fun and very unique design.
SirG: Kryptonian DNA is an existing power, and I believe your suggested wording strays from the existing power.
As to Yellow Power Blast SA, I personally like it that he can continue to use it even after he's out of batteries (with it staying at 3 range and 3 attack); it represents him still being able to use his eye beams.
