Intriguing. I wonder how far this power goes, and if it is dependent on any item, device, tech, etc. I hope it's not like Gladiator's super strength where there is some invisible beam that greatly enhances his power from afar.
I still want Namor's sea-life influence to be explored. DC does not own that power, anymore than they own somebody flying or having eye-beams.
I am still unclear on the overall end-game that Namor is angling for here. Has he still declared absolute war on any human presence in the seas?
