It's the same logic that Loki doesn't want Ragnir to be his shield. Not that deep.
So he prefers to die than to have Ragnir as his shield. I would understand this logic if Ragnir tried to sacrifice for him, which is my point here btw.
At this point it's just laughable that you guys are even reducing Loki to a spoiled brat just cause of agenda, but okay.
Unbreakable diamond level ice, I say this puts Ragnir surely very high in terms of power.
So what, I never denied anything about his mythicals attributes, still It doesnt mean he is top tier.
Now, if you want to discuss Loki being a god tier, Loki actually forced Imu to use multiple named moves, some of which didn't even faze him, and to pump himself with Omen. And that was base Loki alone.
Which named moves? I'm not trying to downplay Loki's efforts, which were amazing, especially AoE and AP, but Imu defeated Loki in his weaked form, without using totally his powers, neither his real sword, which I suppose it's even stronger than Nemesis.
There's a fucking huge gap here, I even think neither Loki or Luffy are above Shanks, especially because I think Shanks fully masterized his Conquerors.
