Crowd Control (commonly shortened to CC) is a blanket term used in MMORPGs (Massive Multiplayer Online Role-Playing Games) and MOBAs (Multiplayer Online Battle Arenas) to describe abilities or spells that remove or diminish the control a target unit has over aspects of itself - aspects such as being able to cast spells or initiate movement commands. As crowd controls impact a unit's combat ability, they are essentially more specialized forms of debuffs - however, this ability to directly hinder a unit's ability to fight means that crowd controls are often given significantly more importance in regular gameplay than normal debuffs, resulting in their special classification.
Slow
The most common form of CC, Slow effect reduces the target's Movement Speed by a certain percent, up to 90%. Most heroes in the game possess some form of Slow effect. People that can inflict slow effect include:
Stun
Heroes that are stunned cannot move, use their basic attack or use skills. Stun effect can last from less than 1 second to 2 whole seconds. Some examples are 
Eudora's 
Ball Lightning, 
Rafaela's 
Holy Baptism or 
Gord's 
Mystic Projectile.
People that can inflict stun effect include:
Immobilize
A form of CC that prevents the enemy from moving, locking them in place. It does not prevent them from using Basic Attack or skills except for most Blink skills or other movement abilities. Some examples are 
Esmeralda's 
Falling Starmoon, 
Miya's 
Arrow of Eclipse or 
Angela's 
Puppet-on-a-String.
Heroes that can inflict this type of CC include:
Taunt
A special form of CC that forces affected targets to get close to the caster and use Basic Attacks against them. The only heroes that can inflict this form of CC are:
Silence
A form of CC that prevents the target from using skills, without hindering Movement or Basic Attacks. Some examples are 
Akai's 
Hurricane Dance, 
Helcurt's 
Shadow Transition (during 
ultimate) or 
Natalia's 
Assassin Instinct.
The only characters that can inflict Silence effect are:
Suppression
A powerful form of CC that disables all sorts of actions.
It will ignore CC Immunity effects like 
Badang's 
Fist Crack, 
Guinevere's 
Violet Requiem and 
Benedetta's 
An Eye for An Eye despite still keeping the invincibility period.
Suppression cannot be removed by:
- Spell
Purify, - Crowd Control removing skills (like Wanwan's Needles in Flowers and Valir's Vengeance Flame)
- Time Controlled Reduction (like Tough Boots).
Heroes that can inflict this form of CC are:
Knock Up / Airborne
A type of CC that launches the target in the air, preventing them from moving or attacking for a few moments, this CC isn't affected by Resilience and can be removed using the 
Purify Battle Spell or other skills that clear CC effects. Some examples are Guinevere's 
Spatial Migration, 
Jawhead's 
Ejector, 
Kadita's 
Breath of the Ocean or 
Ling's 
Tempest of Blades.
Several characters can inflict knock up / airborne effects, including:
Pull
A form of displacement CC that displaces an enemy by dragging them towards the caster or towards a designated location.
Some forms of Pull will have a continuous effect over time while others will pull the targets only once.
Most Pull skills have an AoE effect, except for 
Franco's 
Iron Hook , 
Minsitthar's 
Spear of Glory or 
Diggie's 
Reverse Time, which can only pull a single enemy.
Heroes that can pull enemies towards themselves include:
Heroes that can pull enemies towards a location include:
Knockback
A form of CC that displaces an enemy by knocking them away from the caster or pushing them in the same direction that the caster is traveling. Knock Back distance ranges from barely noticeable, such as 
Balmond's 
Soul Lock or 
Hilda's 
Art Of Hunting, to very long distances, such as 
Chou's 
The Way Of Dragon or 
Valir's 
Searing Torrent, and even slightly knock enemies in the air, such as 
Bane's 
Deadly Catch or 
Lesley's 
Tactical Grenade. Independently from its strenght, Knock Back is a form of istantaneous CC that will stop enemy heroes from casting skills by very briefly stunning them, but won't usually have lasting effects.
