Much like other summons, fiends are crazy characters that can appear midmatch and cause havok.

Fiends appear as tiny voodoo dolls, which will bounce around until eventually coming to a stand-still (they are suprisingly bouncy). When that happens, the fiend itself appears from the doll in a puff of smoke. The fiends do not have any allegiance and will simply attack whoever they can. The dolls can be attacked and launched, and are as heavy as the Soccer ball item. Since the fiends are extremely powerful, most players will team up to launch the doll off-stage, in order to prevent the fiend appearing. Only one fiend can be in battle at any one time.

In addition to the listed Fiends, any Story Mode boss can come out as a fiend, whereupon they will do their (normal difficulty) thing for 12 seconds.
