A '''Jyk''' is an electric, six-spiked orb that moves vertically or horizontally in mid-air. It is encountered in the [[Super_Smash_Bros._Brawl#Subspace_Emissary|Subspace Emissary]] mode of ''[[Super Smash Bros. Brawl]]''. Jyks also go around the perimeter of floating platforms. It cannot be defeated. Some Jyks are coated with fire or a water-like effect rather than electricity.
Jyks cannot be turned into trophies with a [[Trophy Stand]]; players have to clear Boss Battles with 20 characters to unlock its trophy.
| ''A six-spiked enemy. Attacking a Jyk will do no damage, as they can't be defeated. But you'd better believe that a Jyk will deal out damage to you if you get too close. This foe epitomizes player-hindering obstacles--it gets in your way... and it hurts. It definitely isn't thought fondly of by the characters in the game. It may have something to do with its SHARP SPIKES! Ouch.''
