Tentacruel can use one of two Abilities: Clear Body, which prevents opponents from lowering its Statistics by way of moves or Abilities, but its own Moves can still reduce its Statistics; or Liquid Ooze, which causes opponents that use Energy-Draining attacks against it to lose HP instead of recovering HP.

In Tentacool and Tentacruel, an episode that has since been banned, a Wild Tentacool would have a barrel of Team Rocket's "Super Secret Stun Sauce" land on it, causing to evolve into a ginormous Tentacruel. It would proceed to lead an attack on the city, destroying the hotel that was in construction over their habitat amongst other damage until the words from Pikachu and Misty got through to Tentacruel, ending the rampage.
A villain named Captain Crook would use Tentacruel to try and poach the same Wild Lapras that is also in the same family as Ash's Lapras in Viva Las Lapras. Not the only time that a criminal would utilize a Tentacruel, as Cassidy of Team Rocket would use her own Tentacruel in The Search For A Legend. Kim, Kai and Kail would also use Tentacruel for trouble-making purposes in Gotta Catch Ya Later! and Cerulean Blue.
A trainer named Fergus would appear with a Tentacruel in Mewtwo Strikes Back, which was subsequently cloned, with the clone making a subsequent appearance in Mewtwo Returns. Wild Tentacruel make an appearance in The Power of One and Zoroark: Master of Illusions, along with the Pikachu Short "Pikachu's Vacation."

Tentacruel resides in the Underused (UU) tier of competitive battling. With a great defensive typing, solid bulk, and some great utility moves in Rapid Spin and Toxic Spikes, Tentacruel makes for a standout utility Pokémon that is the most reliable spinner in the tier. Since Tentacruel brings immense utility, it can find itself on many different team archetypes in the UU tier. It also has a good Speed stat for a defensive Pokémon and is not complete set-up bait with decent offensive prowess and the threat to burn an opposing Pokémon with Scald, which includes spinblockers like Doublade and Sableye that try to prevent it from getting rid of the entry hazards. It checks threats like Cobalion, Infernape, and Doublade relatively well, and a resistance to Fairy allows for it to check Florges and Sylveon pretty well. Moves like Haze and Acid Spray add to Tentacruel's utility, as the former allows for it to remove boosts against certain foes and the latter can make it so Tentacruel is not easy set up bait against bulkier Calm Mind sweepers and allow for it to break through troublesome Ghost-types like Sableye. It can even deviate from the normal defensive spinner set to run an offensive set that can break through some of its typical counters. However, Tentacruel does not have the best physical bulk, leading to it struggling against physical Fire-types like Entei, which can wear it down through Sacred Fire burns. It also is not as consistent against teams that utilize Spikes due to it being affected by the entry hazards itself and being worn down in the process if it cannot get past a Ghost-type like Sableye.
Tentacruel is also a viable option in the Overused (OU) tier of competitive battling. With a defensive typing that allows it to check numerous threats such as Keldeo, Azumarill, and Clefable, Tentacruel is certainly capable of holding its own in the OU tier. Tentacruel is one of few Rapid Spin users that can beat Mega Sableye with Acid Spray and Scald to wear it down immensely. Tentacruel does suffer from having weaknesses to common attacking types, such as Electric, Psychic, and Ground. It also faces fierce competition as a Rapid Spin user from Starmie, which has access to reliable recovery in Recover, a better Speed tier than Tentacruel, and the ability to go offensive, but Tentacruel does offer some unique resistances and and lacks a Pursuit weakness.
