List of Shortland Street characters (2012)
Kronos appeared in several guest stints in both 2012 and 2014. He was named after the cat owned by a relative of the shows head writer. Kronos was the household cat owned by Luke Durville (Gerald Urquhart). Luke's girlfriend Bella (Amelia Reid-Meredith) disliked the cat and Luke was shocked in February 2012 when he ate her pet mouse. He bought a substitute mouse in the hope Bella would not realise, only for Kronos to kill it as well. Brooke Freeman (Beth Allen) and her sister Bree (Rachael Blampied) later tried to kidnap the cat to scare Luke into moving out, only to fail after Kronos savagely attacked them. On Halloween 2014, Bella was shocked when Kronos arrived to the Cooper household, making her believe that Luke's spirit opposed to her engagement to Dallas Adams (Cameron Jones). Dallas clashed heavily with Kronos and matters came to a head when he had the cat neutered out of spite. Ultimately, Bella realised the presence of Kronos was too much of a reminder of the past and let Lucy (Grace Palmer) adopt the cat.
