Sky-Chis are special abilities of Senseis, first appearing in Skylanders: Imaginators. They have a meter that fills up over time and as they defeat enemies, and when full, can be used to unleash a devastating technique that deals great damage, each unique to each Sensei. Sky-Chis must be unlocked from Sensei Shrines, and only the ones that correspond to its Battle Class.
The Sky-Chi also has its own button to be activated unlike most Skylander moves, and must be held down for several seconds to be activated, as to keep players from accidentally using up the meter.
Though all are thematically different, Sky-Chis from the same classes play similar, such as Cortex, Pit Boss and Golden Queen all summoning attacks from afar.
The ghostly skeleton turns her blades into a lightning tether that connects to Juju Junior like a rope, and both become covered in static. Juju Junior can be controlled to run into enemies, and the tether also electrifies any targets between them, At the end, her blades and Junior come back in a lightning strike around her.
Chopscotch transforms her axe into a jumprope, which goes through her "neck" each time she jumps, causing her skull to launch at enemies. While decapitated skulls persist, the skull on her torso always replenishes between jumps. As a finishing move, she reforms her axe and slams the ground, creating a vortex that turns the skulls into explosive undead energy.
Cortex inserts coordinates into his weapon and transforms it into a staff-beacon-like device, which then draws in satellite strikes. A target reticle can be controlled to indicate the general area of the attacks. Oddly, at the end of it, the reticle itself explodes, scaring Cortex into vulnerability.
Hood Sickle summons a gravity well beneath his feet and uses its power to spin around, firing dark spheres every few seconds. The reaper's movement can be controlled though not the direction he fires at.
Wolfgang summons an audience of skeletal hands, and crowdsurfs on them while playing his theme. The hands are summoned and dismissed according to his movement.
Though Sky-Chi is the first special move tied to a figure gimmick, they are not the first one in the series. In the 3DS version of Skylanders: Trap Team, Trap Masters can use Trap Attacks after filling up their Trap Meter, and they are cinematic moves that always attack in an area of effect for considerable damage. Unlike Sky-Chis, they always have the same effect no matter the animation.
Quickshot Sky-Chis are similar to the Death Blossom Secret Technique.
Sentinel Sky-Chis are similar to the Top Spin Secret Technique.
