Heartless Tsum

The Heartless Tsum is an Emblem Heartless that was introduced in Kingdom Hearts Union χ during the cross event in 2017.

Design
This giant Heartless has two attacks: one in which a gloved hand materializes behind it to give it a poke, causing all the stacked Tsums to tumble and crash down onto its opponent. The second attack takes elements from the LINE:  mobile game; a symbol of a Shadow Tsum appears in the center of the screen, causing the stack of Tsums to all turn into Shadows. Then, the previously mentioned gloved hand plays a "" game with the Tsums, causing them to crash down on their opponent in a similar manner, followed by a magic bomb that falls from the sky and explodes. The Heartless Tsum is composed of multiple Tsums based on pre-existing Heartless, including (in no particular order): One Shadow, two Bandits, two Soldiers, two Powerwilds, two Aeroplanes, two Air Soldiers, one Darkling, one White Mushroom, two Minute Bombs, one Pirate, and one Burrfish.
