Quote1 Kardiak, you're under arrest! Quote2
-- Robin src

Kardiak showed up one day to kidnap children from a playground and trap them within its arterial chambers for unknown purposes. The Teen Titans managed to defeat and destroy this mechanical heart entity, but that didn't end its threat; it managed to regenerate itself and go after other children, requiring the Titans to intervene yet again.


Kardiak can hover in mid-air and project valves that can suck up anything and anyone, trapping them within its arterial chambers. It is also capable of regenerating itself when damaged or destroyed.
