Comment by thatandthis on One Piece - Chapter 1150

atleast in Wano they had the excuse that all the Samuri were either killed or in prison and thats why there was only lame villaigers in the country.

@thatandthis Giant Warriors being Passive Giants aside... 
Is there even an explaination of G** Knight powers/abilities and such somewhere? There has to be some sort of restriction on this cr**... otherwise they would have just done this sh** from the start!

@thatandthis It's OP as heck. It also seems to steal their lifespan and could possibly be the reason why Imu has lived for so long. Just constantly draining others. Also what the fu** is with this arc? I was expecting way more of a fight from the Giants. If two Gods Knights plus an Imu possessed lady can subjugate an entire country, why even bother making an offer to Loki or try to play nice? There has to be a drawback to this or else the arc crashes on its side.

@Lazarus Lucifer I'm thinking the Gods Knights are trained from a very young age, but I'm struggling to see how they get to where they're at unless there's a much bigger batch of potential Gods Knights and they have a live or death match to force the knights to push their limits as much as possible. But the telepathy, teleportation, and immortality BS stems from Imu. I have a creepy theory that Imu steals half of their lifespan or close to it (IIRC Oda said humans can live up to 140, yet we don't see many older Gods Knights) and the farther away from Imu they are, the more using those abilities takes a toll on their already chopped lifespan.
