Thug - Regular (Type 1)
First appearance: Stage 1-1
HP: Low
Projectiles: None
Grab attacks: Suplex
Weapon: Can pick up wooden planks, steel pipes, sledgehammers, torches

This is the first and weakest of all regular thugs. They're common only in stages 1 and 2. You can easily escape their suplex attack by shaking the left analog.

Thug - Regular (Type 2)
First appearance: Stage 1-1
HP: Low
Projectiles: None
Grab attacks: Knee kick
Weapon: Can pick up wooden planks, steel pipes, sledgehammers

Characterized by their bandana, these thugs are more annoying than type 1 regular thugs thanks to their knee kicking grab attack. You can struggle out of it but the first hit is likely to hit.

Thug - Regular (Type 3)
First appearance: Stage 1-1
HP: Low
Projectiles: None
Grab attacks: ???
Weapon: Can pick up wooden planks, steel pipes, sledgehammers, torches

This one's highly similar to type 1. Unfortunately at the moment I can't remember anything special about them. >_>"

Thug - Regular (Type 4)
First appearance: Stage 2-1
HP: Low
Projectiles: None
Grab attacks: Suplex
Weapon: Can pick up wooden planks, steel pipes, sledgehammers, torches, spiked club

This type is characterized by their blond Mohawk. They first appear in stage 2-1 but eventually they become the most common regular thugs in the game. Like type 1, you can easily struggle out of their suplex attack to your advantage.

Thug - Robot
First appearance: Little Devil challenge in Stage 3-1
HP: Low
Projectiles: None
Grab attacks: Suplex
Weapon: Can pick up electric rods

These are the android version of the regular thugs (exclude type 2). They appear only in stage 4.

Skinny Ass - Regular
First appearance: Stage 2-2
HP: Low
Projectiles: Flying daggers
Grab attacks: None
Weapon: Dual blades

This is the most common "skinny ass" thug in the game. They are cowardly by nature and would often run or back flip away from your attacks. They also throw daggers (duck to avoid) and do slide kicks a lot (back flip or side dodge to avoid). If they appear in a group, it might be best taking them out first.

Skinny Ass - Desert
First appearance: Stage 7-1
HP: Low
Projectiles: Flying daggers
Grab attacks: None
Weapon: Dual blades, cutlass

The desert skinny asses are almost no different to the regular ones. All they have in addition is a cutlass hung on their back which they sometimes use. In fact, that cutlass is the best thing about them... since they drop it when they die. *_*

Skinny Ass - Robot
First appearance: Stage 4-6
HP: Low
Projectiles: Flying daggers
Grab attacks: None
Weapon: Dual blades

The android version of a regular skinny ass, they only appear in stage 4.

Chinese Thug
First appearance: Stage 5-2
HP: Low
Projectiles: None
Grab attacks: Suplex
Weapon: None

These are the annoying kung fu masters with long combo sequences consisting of both high and mid attacks (must back flip/side dodge the last hit). They have low HP but in numbers they easily get very frustrating.
