The Pokémon Trainer is a playable character in the game, Super Smash Bros. Brawl. He is the main male character of the games in the Pokémon series that took place in the Kanto region, portrayed in the Pokémon Red and Pokémon Green, Pokémon Blue, Pokémon Yellow, Pokémon FireRed, and Pokémon LeafGreen games. Canonically, in the Pokémon series, the character the Pokémon Trainer is modeled after is actually called Red, with "Pokémon Trainer" being just the name of his occupation.
The Pokémon Trainer is the first playable Pokémon representative in the Super Smash Bros. series who is not an actual Pokémon. Though a selectable character, he is not an actual fighter, instead commanding either of his three Pokémon in the background of the stage.
In Super Smash Bros. for Nintendo 3DS / Wii U, transforming during battle is omitted, so Charizard was made into a separate character, while the Pokémon Trainer, Squirtle, and Ivysaur are no longer playable. He, Squirtle, and Ivysaur appear as collectable trophies, however.

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, he will stay in the background and use three Pokémon to fight for him: Squirtle, Ivysaur, and Charizard. His down special move, Pokémon Change, will switch out between these three Pokémon. The players choose the Pokémon to start with, and they will then be changed in the order Squirtle → Ivysaur → Charizard → Squirtle, and so forth. This is the first time this kind of fighting style has been used in the Super Smash Bros. series.

The Subspace Emissary
In the Subspace Emissary, he allies with Lucas who helps him find his Charizard and Ivysaur. The two also encounter Wario and a large Subspace Army robot, Galleom. They are saved from the robot's detonation by Meta Knight, and they team with him, Marth and Ike afterwards. When encountering a huge Subspace Army group on the foothills of a mountain (Meta Knight has left to retake the Halberd), they are saved by Mario and his team (Link, Yoshi, Pit, and Kirby).
Pokémon's Special Moves
Pokémon Change is a move used by the Pokémon Trainer in the game Super Smash Bros. Brawl. It is his Down special move. Once used, the Pokémon Trainer withdraws his current Pokémon into its Poké Ball, and sends out another one. For example, if he starts off with Charizard in the beginning of the battle, when he uses Pokémon Change for the first time, he would switch his Charizard with Squirtle. If he uses it again, he will send out Ivysaur. Afterwards, Charizard re-enters the battle, and the order starts over again. This attack has many more strategy options, as players can now switch between three characters, and no damage can be taken between switches. This is similar to Zelda and Sheik's Transform move. Like Transform, each Pokémon shares the same HP.
Changing Pokémon can be crucial since each Pokémon has their own set stamina. As the Pokémon's stamina drops, its attacks will pack less power than normal. When the Pokémon is tired out, that's the time to use Pokémon Change. However, the player must not use this move too quickly or else the Pokémon won't have enough time to recover, and will get tired more quickly.
On a side note, if the Pokémon gets KO'd, Pokémon Trainer will automatically bring out the next Pokémon (unless he loses all of his stock lives in a Stock match).
Triple Finish is Pokémon Trainer's Final Smash in the Wii game, Super Smash Bros. Brawl. It is unique in the fact that all three Pokémon - Squirtle, Ivysaur, and Charizard - are used in the attack. When the Smash Ball is collected by the Pokémon currently being used, Pokémon Trainer sends out his two other Pokémon. Then, a text box appears at the bottom of the screen (exactly the same style of text box used in Diamond & Pearl), and the three Pokémon use Hydro Pump (Squirtle), SolarBeam (Ivysaur), and Fire Blast (Charizard), which are all powerful attacks. No matter who it is used against, it will be "super effective" on the opponent, according to the text box. The attack is particularly powerful when a player is close up.
