The Lock

The Lock ((錠前/じょうまえ) ザ・ロック) is the Stand of Tamami Kobayashi featured in Part IV: Diamond is Unbreakable.

Appearance/Personality
The Lock appears as a giant U-Shaped Lock hooked onto the target's heart. As with most Stands, only people with Stand powers can see it. Even the afflicted has no idea it is there. It has no apparent personality. Tamami can also hold The Lock as a tangible item, as shown when he is called by Rohan Kishibe to confirm that Josuke is cheating in their game of dice.



Abilities


Guilt-tripping: By making someone feel guilt, Tamami can then summon The Lock and hook it to the person. Afterward, their guilt on it is multiplied continuously, represented by The Lock growing bigger and heavier, until the victim becomes so guilty they commit suicide. This does not even require the victim to be guilty about something they did, rather, he is able to make Koichi's mother almost commit suicide by making her feel guilty about her son. The Lock's weight, growing with the guilty, can kill the victim if she doesn't commit suicide. However, if the person doesn't feel guilty at all, The Lock doesn't work on him. Also, Tamami Kobayashi says that if someone with a lock on them attacks him, the damage will be reflected on the attacker, but this is never shown.
