Deadman's Coffin

Seeing as I am a fan of Yasuhiro Nightow, I wanted to give my character Deadman a unique weapon reminiscent of Nicholas Wolfwood's Punisher cross weapon and Fangoram's Cerberus Center Head cross gun. The coffin is actually a large rifle that fires super large caliber bullets. It is very heavy and can only be carried by Deadman himself, even with just one hand. Not only that, but the cross on the coffin can be taken off and turned to a sword by a switchblade mechanism on the long side of the cross. =3
