In The Matrix Reloaded there is fight scene between Neo and the Merovingian’s supernatural minions. One of the minions, wearing white, (I’ve setup the YouTube link to start at the relevant time marker.) is using something that looks like a pike with a lot of spikes close to the business end. (Neo eventually takes it away from and kills him with it.)
Looks like a larger than usual morningstar to me. Morningstars were typically one-handed weapons, but I don’t see any particular reason why there wouldn’t have been polearm versions of them, since more or less every other one hander has been declined into a polearm at some point (polehammers, poleaxes, swordstaves, mauls and flails…).
