Injustice Gods Among Us-Mortal Kombat X Scorpion Gameplay Elite VII

Mortal Kombat X Scorpion can be unlocked during his challenge; otherwise, he can be found as a random drop from the above packs as said, but neither will unlock him for direct promotions.
Rivaling Ares' damage and having a passive that grants health surpassing even the mighty Shazam, Mortal Kombat X Scorpion is an unmovable tank that can deal incredible amounts of damage if used well.

Strategy

His light combo ender and special 1 will inflict burning damage. His special 2 will inflict bleeding. All of these - including the possibility to crit - are not counted as part of his passive and will work in Dead Zone, making him a powerful character in this field. The damage over time will not apply life drain.

Doom Slice: Part of it deals fixed damage. It can be unblockable if used shortly after his heavy combo. Only the last hit, a tap and shoot with a widened and easier to hit 200% damage like Deathstroke/Arkham Origins' SP1, deal variable damage. Because of this, and that damage over time specials usually have a 0.5x damage penalty, his SP2 only does 40%~60% of his damage stat, instead of the normal 60%~120%. The bleed damage deals 6% of his damage stat 6 times (36% total) at 100%, but at 200% it is a rather impressive 18% (108% total), for a theoretical maximum of 168% of his damage stat as total damage.Other damage over time effects applied by Scorpion will also crit while a crit damage over time effect is running. This includes even the burn from his light basic combo, as well as The Ibistick. The crit (+50%) and the bleed (+20%) (in the case of his SP2) stack multiplicatively for +80% damage. In the case of the Ibistick, this will increase its maximum damage from 10% of enemy maximum health to 17.4% (the crit period is very slightly longer than the bleed period, so the fifth hit will crit but would not benefit from the bleed).
Note that while Mortal Kombat X Scorpion's base damage is extremely high, it is somewhat misleading, as his Doom Slice deals reduced upfront damage by virtue of being a bleed special, and his heavy basic combo only does 2 hits but is not compensated in damage like Shazam or Doomsday/Prime (it only does 4% of his damage stat as damage twice, as opposed to 5% + 7%).

Interactions
Please note that battles are highly situational: this section only mentions cards that have mechanics that, for any reason, are particularly effective with/against, or particularly ineffective against Scorpion. Having a card that "counters" Scorpion does not mean it is always a good choice.

Good With
Hawkgirl:Her snare on tag in (both versions have it) prevents opponents from tagging to avoid MKX Scorpion's potent damage over time.

Catwoman/Batman Returns: Her +100% damage boost to DoT will greatly amplify Scorpion's specials, allowing him to deal a dangerous amount of damage.

Wonder Woman/Dawn of Justice: When Scorpion applies a DoT to his opponent, especially a critical one, if Wonder Woman immediately tags in after and performs a special, the DoT will be added to the teamwide lifedrain.

Good Against

Characters with low health such as Bane/Luchador for they can be easily wiped out by Scorpion's powerful Burn and Bleed DOT - even more unrelenting when it Crits.

Slow characters, particularly Killer Croc/Arkham and Solomon Grundy: Since their basic attack speed is slow - even more so with Killer Croc's case - Scorpion can easily outpace them and deal massive Burn and Bleed damage.

Contrary to popular belief, Green Lantern/Red Son cannot prevent MKX Scorpion from dealing critical damage through his specials.

Abilities
Reborn Spectre: Reaching 200% Damage on a Special Attack makes its DAMAGE-OVER-TIME damage automatically CRIT. Bonus 8% HEALTH per promotion.
