Recover Lanturn: This is a good idea at first sight, but it's not as amazing as I first thought of it. With Recover, Lanturn can take on Mega Manectric, Thundurus, and Greninja more reliably, and having a method to heal off entry hazard damage is nice. But I still would rather use Rotom-W, simply because its stats, aside from HP of course, are superior to Lanturn's, since it's much faster and hits much harder. Will-O-Wisp is more reliable for burning foes than Scald, and having Levitate to flip off Ground-types lacking Mold Breaker makes it really hard for me to use Lanturn. The only thing I see working for it is a cleric set with Heal Bell, and even then, I would have to seriously weigh my other options before choosing Lanturn. It's not a bad idea by any means, I just don't see the appeal to this is all.
Extreme Speed Hitmonlee: This one had potential, being like a half breed between Lucario and Hawlucha, but kind of comes up short. While Hitmonlee's Special Defense is impressive, it can't take a hit from the physical side worth beans, and it also doesn't have a lot of resistances to take advantage of, so it only inherits Extreme Speed and immediate power from Lucario. As for inheriting Hawlucha's traits, Unburden can go a long way, but it's a one-shot deal that can blow up in your face if someone manages to force a switch. What's worse, Hitmonlee doesn't get Swords Dance, which would have made it a lot more interesting. Normal Gen shenanigans could possibly work, since Extreme Speed would be easy setup for Unburden to take effect, though Extreme Speed is kind of a wasted moveslot after that, since lacking an offensive item AND a setup move aside from Bulk Up makes it weaker than one would think. I'm not so sure about this one to be honest. It might be the other Theorymons on this slate making me bias, but as a whole, not my favorite idea that we've had so far.
Solid Rock Rhydon: Massive defenses? Check. Eviolite compatible? Check. Solid Rock? Well, it's a check now! With Solid Rock, Eviolite Rhydon would pretty much make Rhyperior the new Blissey on OU terms, as the extra bulk from Eviolite greatly exceeds the recovery from Leftovers in this case, and if something is replacing Rhyperior for its role, and Rhyperior is already a pretty good Pokemon, then it's hard to imagine Solid Rock Rhydon doing anything other than succeeding. There really isn't much to say here except that this Theorymon would be amazing, and I can see this one winning.
Parting Shot Absol: I can't tell if this is a buff to Absol or to Parting Shot lol. I mean, Parting Shot is such a cool move, but being learned only by the Pangoro family sucks big time, so seeing it on ANYTHING that's even remotely viable in OU is already one hell of an improvement. Absol really needed this though, since he doesn't have to stay in on a threat to Mega Evolve now, and the ability to scout with it and weaken foes is amazing. Weakening something for a wall to safely wall it and letting a more frail Pokemon have a chance at sucking up a hit is invaluable team support; it's kind of like instant Reflect/Light Screen support, just not making things as durable as the actual screens and switching instantly removes it. Love this one, and I wouldn't be surprised if this Theorymon won.
