>Ghost types are made manifest mainly by the regret of others. Especially powerful ones like [redacted] only come into existence when the regret is so strong that without it the individual in question would lose their memory. Regret becomes a manifestation. This can happen when someone dies really angrily or simply when their feelings are drained from a Psychic move or some other siphoning method.TL;DR Ghosts are formed from the regret of their forebearer.
