Unexpected Yet Effective Counters

I think many are aware of situations such as Spiral countering Serpent or Spider Woman countering the Enchantress, but has anyone found surprising counters to some of the more difficult defenders? I'll share one here - -
Cyclops (Blue) counters Mr. Sinister - Cyclops is obviously much better than he was prior to the buff, and damage to Mr. Sinister from his optic blast attacks can not be recovered

Cheeilth is great for Red Skull and Arcade

Bastion is great for Photon and Zola

Okoye is great for Majority of Cosmic Class

Silk Destroys Zola and Onslaught

Kushala destroys Jean Grey and Dust

Crossbones vs sinister

BRB against Yelena are my non-obvious ones

Iron og and gladiator take photon easily

Luke takes dark phoenix quite well just get the concussion up

Terrax isn’t very common anymore apart from raids but mr knight takes him well

Punisher 2099 is a great counter to bullseye. Just stall till you enter overdrive and throw sp2 for the armor break. Bullseye will never enter sp1 if you play it right

An old-school favorite: Bishop counters Nimrod.

Nimrod deals energy damage, granting Prowess to Bishop. This gets turned into a Shock, which triggers Bishop's feedback, which kills Nimrod.

archangel can reliably parry stun Red skull .

zemo takes Spiderwoman pretty well and can take on knull too in bgs with a sp3 rotation . Knull has crazy light reach though so I parry at the start as you can’t hit him first at the start of the match . Knull takes yelena well too

I like these sort of discussions so I’ll add some of my own:

QS is pretty good for Dark Phoenix. The big draws are that his Whiplash and Trauma damage seems to bypass Dark Phoenix’s Safeguard and Damaging effect resistance, plus the fact that his multihits means you’ll practically never suffer from her post-special Nova Flames. Wither and Slow also help. The only downside is he can’t counter the Immortality and its accompanying Nova Flame, but that’s a whole lot better than most champs can offer.

Not fast enough in BGs, but in War Gorr is a very safe Yelena counter for much the same reasons he’s good against Bullseye; the constant Bleed triggers through block just feed him a ton of Regen Buffs that make him immortal if you’re not absurdly reckless. This includes working on Node 49 with Polka Dot Power. I’m not sure if this one is really unexpected per se, but I don’t ever see anyone mention it so I’m throwing it out there.

Masacre’s big damage moment being a non-crit sp2 into block lets him pull a Crossbones and potentially take down a defending Mr. Sinister. Just make sure to keep him from throwing sp1, or the reflected Incinerates will eat you alive.

If you’re caught against a duped Medusa without a Buff or Auto-Block counter, Yondu works fine. ML to trigger her Auto-Block with Yondu’s Yaka Arrow, which is non-contact and thus doesn’t get you Parry Stunned. The Auto-Blocks don’t even really slow him down much since he still inflicts his Ruptures through block.

Awakened Doc Ock is one of the only champs in the game who can prevent Enchantress from ever throwing a single special and thus activating her Spells, meaning you’ll only ever have to deal with the set of Spells she starts with. This isn’t usually possible since Enchantress is Immune to Power Lock and gains back all Power she loses from things like Drain or Steal over time, but Doc Ock’s Physics Breakthrough immediately Drains all Power the opponent would gain from any source, so it gets around her safeguards and prevents her from gaining power once active.
