One of those green lantern amps is I'm pretty sure. There is several gl's tho each with different amps and versions. I was thinking Yat was like a tier below like Spectre or something. Isn't he a highly amped Kyle or Hal?
Most of my knowledge about GL's is from here to so that's why I usually ask questions first before I answer or choose a side. And if it's something I care enough about to debate then I will eventually check out their respect thread.
