Gonna add Capcom's most iconic beat em up, Final Fight.
Holy shit the elites are a menace.
(same Hugo in Street Fighter) Andore, Poison/Roxy (Roxy is lesser health variant), El Gado/Bollywood (Bollywood is lesser health variant, though low health enemy that throws molotovs is also called Bollywood). Challenging enemies, life threatening in group.
First what makes them dangerous AF is they get basic privileges that every Final Fight fodder gets: if they are close enough they are happy to stunlock you in place or knock your ass down with unreactable attacks. Since you can only attack left or right at a time it's especially dangerous to get cornered from two sides by multiple enemies. In that case you can't fight back and the damage stack is so high you die in seconds. Now what's unique about the elites?
1) Hugo stands his ground in Final Fight: he has comparable normal attack range to you and has some very high priority attacks. They are the choking grab, grab into piledriver, the ground pound and running chest bump, latter especially is difficult to avoid. If he does any of other three signature attacks you are fucked.
2) Poison is really mobile jumping around and casually trying to divekick you. Your back is a high priority target for her so it's best if you don't let her jump over you OR grab her immediately on landing and throw her back. One Poison is perfectly manageable but if there's more they can easily jump around and stun you from both sides. When approaching carelessly she may do spin kick that knocks you down.
3) El Gado is the most asinine enemy in this lineup, no contest. With his knife out his normal range is superior to yours, ready to stablock you. He also throws knives when you are not quite close enough to hit him back. His signature attacks are the unreactable sweep in close range and screenwide leap where he stabs you while getting behind simulatenously. He also has high health comparable to Hugo, which is insane for a ranged enemy. There is an encounter entirely consisting of El Gados and Bollywoods with total number of 8 or so, the death is guaranteed.
Final Fight is a fantastic game, play it and face the legendary bastards of Capcom. You can see really similar enemies in God Hand, particularly fat guys or the knive dudes.
