Triple Finish

Triple Finish (, Trinity) is the Pokémon Trainer's Final Smash.

In Super Smash Bros. Brawl


Pokémon Trainer calls out all three of his Pokémon to perform a synchronized team attack. Squirtle uses, a multi-directional spray of water. Ivysaur uses, a narrow beam of concentrated light, to create a wide projectile that holds targets in place. Charizard uses, firing six large flames in the shape of the Japanese character "" that also act as the move's finishing blow. Once the attack has ended, Pokémon Trainer recalls the two inactive Pokémon, and the Final Smash ends.

During Triple Finish, Pokémon Trainer shouts, "Take this! Triple Finish!" with an accompanying dialogue box (which incorrectly reads "Take that!" instead of "Take this!") like in the Pokémon games. A moment later, the text changes to "It's super effective!", even if it doesn't hit any opponents. The text box hides damage meters and appears in Snapshots. The camera zooms in on the trio at the start of the move, zooming out as it progresses.

The move does more damage to opponents that are closer to the Pokémon, where they can take up to 58% damage. However, if the opponent is too close, they will be sent straight up and out of the attack by a concentrated ball of energy in front of the Pokémon. It can also be used in mid-air.

In Super Smash Bros. Ultimate
The move functions very similarly to how it worked in Brawl. The maximum damage dealt has decreased to 51.8%. Opponents now get properly trapped in the attack as long as it connects, fixing the issue of opponents being launched upwards when used point-blank.

The male Pokémon Trainer now properly says "Take that! Triple Finish!" to match the dialogue box and the new female Pokémon Trainer says "Go! Triple Finish!", with her own dialogue box reflecting this. Also, Squirtle's Hydro Pump has been reworked into a whirlpool, Ivysaur's Solar Beam is wider, and Charizard fires five Fire Blasts instead of six.

During the attack, all three Pokémon will have glowing yellow eyes, but only the active one will have the glowing Final Smash aura.

Origin
The concept of Triple Finish is based on a common occurrence in the Pokémon franchise outside the main series games, most notably the, in which multiple Pokémon are instructed to attack in tandem, usually to defeat a larger threat. Most pertinently, the of the  manga has Blastoise, Venusaur, Charizard and the other starter Pokémon final forms from the first three generations use their ultimate attacks in tandem to defeat a monstrous Kyogre.

All three of the attacks used in this Final Smash, Hydro Pump, Solar Beam and Fire Blast, have been featured in every main installment in the franchise, and have always been learnable by Squirtle, Ivysaur, and Charizard, respectively. Prior to Generation III, these moves were known for being the strongest moves of their types (Water, Grass, and Fire respectively). They are each Special moves with a very high base power of 110 (120 for Solar Beam and prior to Generation VI), but Hydro Pump and Fire Blast have low accuracy values (80% and 85%, respectively), and Solar Beam requires a full turn to charge. Fire Blast originally had a 30.1% chance to inflict a burn on the opponent, but this was nerfed to 10% in Generation II. Squirtle can learn Hydro Pump at Level 42 in and has been able to learn it since. Ivysaur learns Solar Beam at Level 54 in Generation I, but can also obtain it via TM22. Charizard and other Fire-types could not learn Fire Blast naturally in Generation I, but could learn it via TM38 after defeating Blaine, the seventh Gym Leader.

The concept of three Pokémon being active at once was not possible in the Pokémon series at the time of Brawl's release; the most legally allowed in a Pokémon battle was two. However, s and s were introduced in the Pokémon series in Generation V, where each Trainer sends out three Pokémon at once; the former functioned similarly to a Double Battle, and the latter allowed trainers to switch between three active Pokémon without using up a turn to switch. An episode of the Pokémon anime prior to Brawl additionally featured the first non-official Triple Battle in the series. Generation VI kept Triple Battles and Rotation Battles, though both were dropped in Generation VII.

The text box that appears resembles the ones that appear during battles in the Pokémon series, describing what actions are taken and their effects. The style of the text box resembles the latest installment of the series in each game the move is featured in: Diamond and Pearl in Brawl and Sun and Moon in Ultimate. Ironically, neither installment features a battle format for three Pokémon at a time.

The phrase "It's super effective!" is used when the type of a move used by a Pokémon is strong against the type of the opposing Pokémon (for example, a Fire-type move against a Grass-type Pokémon). In these instances, the attack will deal double or quadruple (if the target Pokémon has two types with the same weakness) the normal amount of damage, and is accompanied by a different damage sound effect.

Trivia

 * This Final Smash can be used to view off-camera pieces of scenery on stages without pausing and changing the angle. If one stands at the edge of the screen and faces away from any stage before activating the attack, the zooming effect will show graphics that one would not ordinarily see mid-match.
 * In Brawl, the text box present when using this move is identical in appearance to those from the Generation IV Pokémon games. In Ultimate, the text box was updated to match the appearance of those in the Generation VII games.
 * The star-like symbols fired by Charizard are the kanji "dai", meaning "great" or "large", referencing Fire Blast's Japanese name, "Daimonji".
 * Hydro Pump is also used as Greninja's up special move, with a completely different function and animation from Squirtle's use in Triple Finish.
 * While the move is mostly functionally identical regardless of which Pokémon was in play at the time of activation, when gained through the Final Smash Meter, Squirtle's variation deals a negligible amount less of knockback than Ivysaur or Charizard (1.009x knockback multiplier, as opposed to the other two's 1.01x, all compensated by an equal reduction in damage).
