Surume Ika no Yari

Known as the Dried Squid Spears, these are the eight polearms carried by the giant-squid fish-man Ikaros Much, one clutched in each of his hands. Holding officer rank among the New Fish-Man Pirates, he brandishes all of them at once, so their sheer count alone can give him an edge over most opponents even though he rarely fights with them at length.

What makes the weapons dangerous is their tips: every spearhead is a dried squid that pulls the water straight out of any body it pierces, reverting to an ordinary squid as it feeds. Ikaros put this to use when he skewered a fellow pirate who had offended him, leaving the target completely drained. The flaw in the design shows against enemies that hold no moisture to steal, which is why the spears do nothing to the skeletal Brook or to Franky while he is sealed inside his General Franky exoskeleton.

Ikaros Much is the only wielder of these spears. Beyond the eight-spear set, his hair is secretly styled into a single hidden spear beneath his helmet, which he saves as a final measure. That concealed weapon, called Usubon no Yari, glows with light and can supposedly bore through undersea mountains, though his attempt to drive it into Franky never connected. During the Fish-Man Island conflict he tried to stab Nami with one of the squid spears while Zeo pinned her, only for Brook to block the strike, after which Ikaros was blindsided by Franky and eventually defeated by the Franky Radical Beam.
