I don't think Rankanshu even needs a Evo. because he is better than gongrashu( the ghost made or somthing
)
Haha, this post seriously won the thread. Congratulations!
Anyway, why would they evolve?
Rankurusu and Gochiruzeru are equal to eachother, if one doesn't evolve the other won't evolve either. These two are like the version exclusives as seen a lot in RSE (Sableye & Mawile, Volbeat & Illumise, Seviper & Zangoose etc.). I don't think they will evolve (pre-evo possible but unlikely).
Gigaiasu won't evolve either. Again, pre-evo possible but I don't think so, although still more chance than the previous 2 having pre-evolutions. Neither will he evolve from either Nosepass or Probopass. Probopass would be impossible for several reasons;
1. Probopass is evolved by a special method, Pokemon which have evolved by a special method never evolve again (except Porygon, although Porygon is artificial, thus different).
2. Probopass is Rock/Steel. It hasn't happened before that Pokemon first gain a new type and lose them later in the evolution (that wouldn't make sense either).
And the reason that it won't be a Nosepass split-evo is simply because of their abilities. Nosepass has Sturdy and Magnet Pull. Since we know that Gigaiasu has only Sturdy, one may ask what would happen to the Magnet Pull? Further they don't share any similarities apart from their color.
But (just to say), the last reason can't be applied to Luvdisc/Mamanbou. Yes we know that Mamanbou has Hydration and Healing Heart, while Luvdisc only has Swift Swim. But we don't know what will happen to Luvdisc's abilities in the 5th gen. Since Healing Heart is a new ability, it might be possible that Luvdisc also gets Healing Heart. And so making only the Swift Swim turning into Hydration upon evolving (what could be possible).
And no, even though Pokemon are able to gain abilities, it is impossible for them to lose abilities, so we do know that Nosepass also has Sturdy and Magnet Pull in generation 5.
