This looks like a meme but CHOICE BAND GIGA IMPACT LOL YOU KILL META MEGAGROSS IN 2 SHOTS LMFAO
STUPID ASS VERLISFY LOOKING MEGA WARTORTLE ALSO GETS SHOT IN THE HEAD BY IT.CORVIKNIGHT EH,SCREW THAT BIRD 2HKO LMAFOOXXXDXXD
nah all seriousness though Slaking does have a tiny nice as an absolute nuke
I won't be too harsh on you, seeing as you just joined about an hour ago, but here is some advice:
For starters, big damage is nothing if you aren't consistently dealing it our about to sweep.
For Slaking, almost any Pokemon that can survive one of its hits (if not immune depending on what it is locked into) can be counter-productive at best or detrimental at worst.
With Slaking and Giga Impact/Hyper Beam, you let your opponent do what the next turn always (and that's if they don't just protect).
Take a this match-up of Slaking vs Slowbro, facing off in a 1v1.
252 Atk Choice Band Slaking Giga Impact vs. 248 HP / 96+ Def Slowbro: 328-387 (83.4 - 98.4%) -- guaranteed 2HKO after Leftovers recovery
Normally, if a Pokemon without Truant using a regular move did this sort of damage, it would be unstoppable.
But since Slaking has Truant, the Slowbro in this scenario can do a lot.
-Slowbro can just Slack Off all the damage, knowing Slaking can't move the turn after.
-Slowbro can try to Scald Slaking twice, which has a 51% chance that either hit will burn
-A combination of those 2 things
-Slowbro can do any of the above, then can just switch into a Resist like Corviknight or a Ghost type like Dragapult, who will force Slaking out, giving them a free turn to do damage, set up, or have the advantage in a double switch (well, Corviknight would actually get 2 free turns, where it can bulk up).
Secondly, understand the term diminishing returns and "effective damage".
In Pokemon, most things are balanced by external factors like their BST distribution, negative effects, ect.
Obviously, a Pokemon with 255/255/255/255/255/255 stats is going to be better than 250/255/255/255/255/255, assuming that they are identical in every other way.
Problem is that it isn't by much, since the numbers are just so high.
An other example is the BP of Max moves vs the BP of Z-moves.
Z-moves in general would often be about 175 BP, give or take, while Max moves would be 130 BP-140 BP.
It's a 35-45 BP difference, but you already are doing so much damage with Max moves that the extra 40 BP rarely makes a difference.
That brings me to my other point in "effective damage".
By Effective Damage, I mean "How much of X moves can Y Pokemon take?"
To wrap back around to the topic, in the scenario before, Slowbro can take 2 CB Giga Impacts from Jolly Slaking, not even fully invested.
You know what else can kill a Slowbro in 2 hits while not being as detrimental?
Well aside from Special Attackers;
Mega Charizard X:
252 Atk Tough Claws Charizard-Mega-X Outrage vs. 248 HP / 96+ Def Slowbro: 195-231 (49.6 - 58.7%) -- 71.1% chance to 2HKO after Leftovers recovery
Darmanitan-G:
252 Atk Choice Band Gorilla Tactics Darmanitan-Galar Earthquake vs. 248 HP / 96+ Def Slowbro: 198-234 (50.3 - 59.5%) -- 82.4% chance to 2HKO after Leftovers recovery
Weavile:
252 Atk Weavile Knock Off (97.5 BP) vs. 248 HP / 96+ Def Slowbro: 230-272 (58.5 - 69.2%) -- guaranteed 2HKO
252 Atk Weavile Knock Off vs. 248 HP / 96+ Def Slowbro: 156-186 (39.6 - 47.3%) -- guaranteed 3HKO
(the cumulative damage it still a 2HKO)
Ferrothorn:
0 Atk Ferrothorn Power Whip vs. 248 HP / 96+ Def Slowbro: 188-224 (47.8 - 56.9%) -- 38.7% chance to 2HKO after Leftovers recovery
MelMetal:
252+ Atk Choice Band Iron Fist Melmetal Thunder Punch vs. 248 HP / 96+ Def Slowbro: 266-314 (67.6 - 79.8%) -- guaranteed 2HKO after Leftovers recovery
Mamoswine:
252+ Atk Choice Band Mamoswine Earthquake vs. 248 HP / 96+ Def Slowbro: 207-244 (52.6 - 62%) -- 99.6% chance to 2HKO after Leftovers recovery
Tyranitar (locked into Stone Edge, not even needing Crunch):
252+ Atk Choice Band Tyranitar Stone Edge vs. 248 HP / 96+ Def Slowbro: 211-249 (53.6 - 63.3%) -- guaranteed 2HKO after sandstorm damage and Leftovers recovery
Dragapult (which actually OHKOs):
252+ Atk Dragapult Never-Ending Nightmare (175 BP) vs. 248 HP / 96+ Def Slowbro: 456-536 (116 - 136.3%) -- guaranteed OHKO
Not only do these Pokemon have the same ability to 2HKO Slowbro, they can actually kill Slowbro without crits, and they provide other positives as well.
Zard can utilize its typing to tank powerful fire attacks.
Darmanitan-G is one scary S.O.B. and can force switches.
Weavile is fast, has priority when it's too slow, and can cripple walls.
Ferrothorn can soak up powerful attacks it resists, lay hazards, and punish fast Pokemon/Contact abusers with Gyro Ball and Iron Barbs.
Melmetal is physically tanky with a steel typing and hits really hard.
Mamoswine can set up rocks while threatening out Defoggers and other rock setters.
Tyranitar has a surprisingly good typing, mixed with a Spd boost, provides Sand for its teammates and sand to nullify leftovers, and hits hard too.
And Dragapult is super fast, can dip both ways, and being a Ghost provides immunities to 2 types.
Slaking does not provide any of these besides being tanky (which is nullified when Truant gives your opponent a free turn, which could be 2 attacks).
The extra fire power Slaking does only really matters in this scenario if you had done chip damage prior, which kind of contradicts the point of running a Pokemon solely for massive damage.
Hopefully this helps you in the future with discussion and explains why Slaking should remain unranked.
