I just finished my second full playthrough of White 2, at least the main story before the post-game, that is, and I still love the game as much as I did back in 2013, it's such a great game. But anyway, I used a loot of mons for my White 2 playthrough, but one of the most out of the box ones I decided to try out for fun is this little machine of gears we call Klinklang, which I of course caught as a Klink in Chargestone Cave and spent a lot of the playthrough raising it alongside my many other mons.
This thing is one of the most overlooked Pokemon in Unova, partially because it's a bunch of gears which some people were turned away from, the other partially because it doesn't strike as immediately awesome to use like the other Chargestone Cave mons: compared to Galvantula's Compound Eyes Thunder, Ferrothorn's god tier bulk and Curse+Gyro Ball hitting like a truck, or Eelektross's wide movepool, Klinklang has a fairly barren movepool. However, like its fellow Chargestone Cave brethren, Klinklang does fortunately have a unique battle gimmick of its own that is fun: Shift Gear! A Dragon Dance amplified, with Klinklang boosting its Attack and sharply boosting its Speed in one turn. Unfortunately, this didn't come until very late in the game, but that aside.
I found this mon to be surprisingly fun to use. While it doesn't get its Shift Gear gimmick until very late in the game at Level 54, it proved itself a surprisingly valuable member of my team. As a Klink, it was pretty weak, but its Steel typing still came in handy at times, and as Klang, it was also a pretty decent Pokemon, and its Dragon resistance came in handy at Opelucid. Aside from its STAB Gear Grind, it could weaken the opponent's Defense with Screech and then hit hard with Gear Grind, or another thing is that Klink or Klang could also act as a pseudo Electric-type with its Electric moves in ThunderShock, Charge Beam, and later Discharge, which meant I could use it to pick off Flying and Water-types with a Discharge every now and then.
But it is once Klang evolved into Klinklang that it really hit its stride. Even though it still had to wait five levels to get Shift Gear, it was such a useful mon and I was pleasantly surprised. The big thing about it is that its Steel type, combined with its usable bulk on both sides, especially physical, made it incredibly useful with its many resistances while it could hit back with either Gear Grind or Discharge, and it proved useful against a myriad of opponents during the Team Plasma takedown, especially Zinzolin and his Ice-types, which Klinklang could single handedly take on and wall, and later on, it proved its usefulness against Ghetsis really well: first walling Cofagrigus, not giving a damn about Toxic at all, and I wore it down with Metal Sound+Discharge to pick on its weaker special bulk, and later on it also completely walled Ghetsis's Hydreigon, taking its onslaught of LO boosted physical attacks while retaliating with Gear Grind to wear it down.
I eventually did manage to get Klinklang to Level 54 and above during Victory Road, and from there it really proved a valuable member of my team for the endgame. I also grabbed the Wild Charge TM there and that helped a lot, and gave it Magnet Rise from the Move Tutors. It managed to set up on and defeat a few of the E4's mons such as Shauntal's Drifblim, Grimsley's Liepard, and it could also use Caitlin's Sigilyph as setup bait though I didn't need to since my Krookodile was wiping the floor with Caitlin anyway. It was the biggest and most clutch member of my team against Iris, however, and it managed to cleanly sweep half of her team once she was down to Archeops, Haxorus, and Lapras. I used Archeops as setup, then swept by KOing Archeops with Gear Grind, using Magnet Rise on Haxorus so it couldn't hit Klinklang with Earthquake, then 2HKOing with Gear Grind (great thing is if I had boosted a bit more, it would've bypassed the Focus Sash and KOed Haxorus cleanly), and then KOing Lapras with Wild Charge. It ended up being a great endgame member and raising it from humble little Klink was very much worth it.
I'm only beginning the post-game, but I fully expect Klinklang to continue being a fun sweeper for the post-game portion.
