Malc is Luke Harding's Booty Buddy. Malc, although non gender-specific, is referred to by Luke and the narrator as a 'he'. Malc has been severely damaged and repaired on more than one occasion.
Being a machine, Malc doesn't have an emotional relationship with any of the other characters. However, he still has strange relationships with a number of the main characters.
Malc cannot 'get on' with his assigned FI because he doesn't have the capacity to. However, he has been programmed to protect Luke and has been seen to risk his own 'life' in order to do so on at least two occasions. For further information on those incedences, see Ms Kee's Funeral and Marylebone Freeway Incident. Malc is shown some affection by Luke, but realises that he cannot treat Malc in the same way as the would treat other humans like Jade Vernon.
He has the following capabilities/features:
Short-range X-ray probe
Identity card scanner
Bullet-proofing in some areas
Maximum Defense mode
