Alright, let's do some calcs, then.  Let's see...for fun, I'm just going to list every single Fire type (and Seikamater cuz of Elementalist)

Alright, now let's hit them all with various moves while Stealth Rock is up.  I'll assume this is at Level 100 and our Metalynx has 252 Atk/4 Def/252 Spe with an Adamant nature.  Moveset is going to be Leaf Blade, Meteor Mash, Earthquake, and Swords Dance (this is the set from Jabuloso's Metalynx guide from ages ago).  For the defending pokemon, I'm going to assume they have speedy offensive sets for all of them except Antarki (248 HP/252 Def/8 Sp Def), Inflagetah, M-Inflagetah, Beliaddon, and Seikamater (Latter four will have 248 HP/252 Offensive Stat/8 Defense).  None of them will be holding any items in these examples (with the exception of mega stones)

Leaf Blade and Meteor Mash

Leaf Blade and Meteor Mash both have 90 power, so I'll categorize the calcs into neutral, 2x resistance, and 4x resistance for those moves.

Earthquake

I'll do something similar for EQ, too.  SE EQ, Resisted EQ, and Neutral EQ.  Pajay lucks out here, not being weak to any of Metalynx's moves at all.

SE Earthquake

Chimaconda: 252+ Atk M-Metalynx Earthquake vs. 0 HP / 4 Def Chimaconda: 552-652 (166.7 - 196.9%) -- guaranteed OHKO

Krilvolver: 252+ Atk M-Metalynx Earthquake vs. 0 HP / 4 Def Krilvolver: 288-340 (100.3 - 118.4%) -- guaranteed OHKO

Beliaddon (Defiant/Disenchant): 252+ Atk M-Metalynx Earthquake vs. 248 HP / 8 Def Beliaddon: 250-296 (57.7 - 68.3%) -- guaranteed 2HKO after Stealth Rock

Beliaddon (Intimidate): -1 252+ Atk M-Metalynx Earthquake vs. 248 HP / 8 Def Beliaddon: 168-198 (38.7 - 45.7%) -- guaranteed 2HKO after Stealth Rock

Baitatao: 252+ Atk M-Metalynx Earthquake vs. 0 HP / 4 Def Baitatao: 232-274 (72.2 - 85.3%) -- 75% chance to OHKO after Stealth Rock

Resisted EQ

Seikamater: 252+ Atk M-Metalynx Earthquake vs. 248 HP / 8 Def Seikamater: 68-81 (13.2 - 15.7%) -- possible 5HKO after Stealth Rock

Neutral EQ

Firoke: 252+ Atk M-Metalynx Earthquake vs. 0 HP / 4 Def Firoke: 190-224 (63.1 - 74.4%) -- guaranteed OHKO after Stealth Rock

Frikitiki: 252+ Atk M-Metalynx Earthquake vs. 0 HP / 4 Def Frikitiki: 169-199 (58 - 68.3%) -- guaranteed 2HKO after Stealth Rock

Now, this is all just from M-Metalynx's side of the equation.  This isn't factoring in how fast and powerful its opponents are.  Still interesting data to look at, though.
