Heavy Bouncer
From Ratchet & Clank wiki
The Heavy Bouncer launched an even bigger bomb than its predecessor, which exploded into bombs about the same size as the normal Bouncer shots that could whiteout the screen. It was possible to use the Heavy Bouncer to kill Chainblade, although not in challenge mode, with one bomb if all the bomblets were accurate enough. This also worked on the B2 Brawler.
