Looking at their roles alone, two of these five could be from mafia: Foggy, Weak, Notty, Pink, Myu. Five people is a lot when we have 9 players on the field, so I'm pretty confused now.
The following are eliminated from the list of potential mafia: Ltin, since even though his role might have to do with alien abductions, I doubt it because his visits involve going to someone's house, instead of abducting someone away from their house. Unu, because mafia doesn't need two roleblockers. Iggish, because his role is very town-esque. Mulbery, because I know myself best, woof. Now among those five people I don't think Myu is part of mafia because I think that Fog is mafia and Fog has pointed out himself of Ender the medic's ability to heal people. For Pink, I don't think she's mafia either, which leaves me with three players: Foggy, Weak and Notty.
I was rethinking about Iggish's role and that perhaps he might be some sort of Alien President. But since it seems like alien roles have the word "alien" in them, for Iggy to be mafia would require Pink to be mafia as well for her to intentionally hide the alien aspect of the president role. Also, due to that Freudian slip from Foggy a while ago I don't think Iggy and Fog can possibly be from the same Mafia team. Weak and Notty can't be part of the same mafia team either because that wouldn't make sense, which leaves me with the following mafia teams left: (I know I'm doing this the second time but this is after some extra thinking so bear with me)
1. HK, Oog, Fog, Weak
2. HK, Oog, Fog, Notty
3. HK, Oog, Iggy, Pink
in that order of probability. I honestly doubt #3 or #2 but I'm leaving them in there for the sake of completion and I don't want to rule them out completely.
