Someone tell me why Pyroar is here. Please. It may not have the greatest typing, and it is SR weak, but really. 106 speed? YES PLEASE. 109 Spec Attack? YES. It may have lack of coverage, but I can see a Scarf or Specs set with Overheat, Fire Blast, Hyper Voice and filler be a decent set. Remember, this is a Pokemon with better offensive stats AND speed AND bulk than Manectric, albeit with a worse typing and coverage. Either it will be banned outright, or number one in NU.
Really? Hell, Jynx has a sleep move, fantastic dual STAB, good coverage, Dry Skin, Trick, Nasty Plot, great Speed, fantastic Special Attack, etc. and doesn't break the tier. So why would a Pokemon with a mediocre movepool, less Special Attack, no good abilities, less Special Attack, less swag, etc. break NU? Also, if we're comparing it to Manectric, it wouldn't have even been that great in BW NU, and it had Lightningrod, better Speed, better Special Attack, Volt Switch, and Switcheroo on its side. There are a lot of components to Pokemon, and good Speed and dual STAB doesn't break it at all.
I also wanted to bring up some other possibilities for NU Pokemon. I'm thinking that Manectric/Houndoom both have potential to come down to NU. They have really, really underwhelming Mega Evolutions, and their base forms aren't anything to write home about either. To be honest, I think Manectric and Houndoom both would have been ok in BW NU lol. What really, really hurts these two, though, is that they are competing with other Mega Evolutions for a spot on every team. Why use Mega Manectric or Mega Houndoom in UU over something like Mega Absol or Mega Heracross? And in RU, obviously this is pure speculation, but I'd think that we'll see Mega Aerodactyl, Mega Medicham (which is incredibly similar to its base form), perhaps Mega Gardevoir (this one might be a stretch because it could very well end up in UU), Mega Banette, etc. I'd imagine that they'll still see a lot of competition from superior Mega Evolutions, even in RU, so it -could- be that we see these two down here.
I also really think Heliolisk is going to end up down in NU. Dry Skin is a really cool ability, but outside of that and its good Speed, it really doesn't have a whole lot to make it stellar. 109 SpA is good, but with only Thunderbolt and no Hyper Voice for STAB, it doesn't seem like a high quality wallbreaker. It does have Surf and Grass Knot for coverage, but again, I'm not sure if it makes it stand out much as a top-tier threat.
Of course, the above examples of possible NU Pokemon are definitely more of a stretch than what was outlined in the OP, but the only other Pokemon in the OP that's not obvious NU material is Aurorus. I think there's potential for these three to end up in NU, and while Heliolisk probably wouldn't (imo) make a huge splash in the meta, the Mega Evos might. I think it'd be interesting to see NU with the least appealing of all the Mega Evos.
