Luigi's Mansion: Dark Moon

[Chaoxys]

Honestly we haven't seen any ghosts with real character. The portrait ghosts of the first game seemed like real people... who died. They had their own distinct look and background story.

Idk, the minor enemy ghosts seems to have more personality than the original minor ghosts in LM (I mean, from what I've seen, you can usually see them goofing off and what not before they notice you). The bosses we've seen on the other hand seems rather basic, although to be fair, all we've seen is about 5 seconds on the brainy ghost, and 3 second of the giant spider, so I think it's far to early to judge them.
