The Riddler is rarely seen without some manner of staff or cane, typically topped by a question mark.
History
While some versions have no functions beyond the aesthetic (and serving as an emergency melee weapon), most contain some remote-control device through which the Riddler can trigger one of his many gadgets.
More advanced versions could also deliver a powerful electric shock, or even contain a built-in rifle.[1]
