Cloaker

The Cloaking Dagger is a special weapon for Dr. Nefarious and what it can do is that he turns invisible and if you press the melee button he'll do a super powerful melee attack. It can be used in any situation like if your on Planet Magnes and a scanner is blocking the way then Nefarious can use the Cloaking Dagger to sneek in front of it and destroy it.
