So you're making this wild claim based on the fact that a near halfdead Loki got knocked down by Luffy when he was still in seastones? It's the contrast, Loki was so fucked up and he still managed to pull such an attack on these circumstances.
Bold: Sure, maybe wait till it's his turn as the antagonist of this arc? Loki is known to be a trickster and just like he'll trick the sh, he's already tricking you.
Kaido was near death when he took Oden's attack; Loki got tortured by a HK for 30 minutes at least and then Shamrock, another top tier, stabbed Loki multiple times with his Cerberus sword.
