Friend's of Ash 3 from Pokemon

Zoey (ノゾミ Nozomi)
Zoey is an experienced Pokémon coordinator from Snowpoint City and Dawn's main rival. Unlike most rivals, she often gives out helpful advice, and helps out in certain situations instead of fighting and taunting Dawn all the time. Zoey is initially disdainful of those who participate in both Gym battles and contests because she believes that trainers who divide their efforts do not full-heartedly compete in both disciplines. However, she changes her outlook as she meets trainers who are able to successfully manage both while respecting the hard work required. Zoey first appears in the episode of "Mounting a Coordinator Assault". The Pokémon she has with her are Glameow, Mismagius, Gastrodon, Lumineon, Gallade, and Leafeon. In "A Grand Fight for Winning", she defeats Dawn in the final stage of the Grand Festival and wins the Ribbon Cup.
Zoey becomes a very helpful addition to The Ketchum Alliance, Due to wanting to never lose her Friend and Rival, Dawn.
Zoey has been chosen by the Go Princess Pretty Cure's and Maho Girls Pretty Cure's to be part of the Dream Warriors, With Kari holding the Wish Maker Whistle that will allow the Dream Warriors to have powers that they like, In Zoey's case, She gains the Abilities of a Cat to match her Glameow, So you could say Zoey going by the Alias the Cat-Girl of Snowpoint City is the Pokémon Worlds version of DC's Catwomen and Marvel's Blackcat.

Kenny (ケンゴ Kengo)
Kenny is one of Dawn's childhood friends and a rival coordinator. He frequently calls her by her nickname, 'Dee Dee' and is best friends with Barry. Kenny makes his debut in Getting the Pre-Contest Titters and Settling a Not-So-Old Score, where he and Dawn enter the Floaroma Pokémon Contest. Eventually, he is able to qualify for the Sinnoh Grand Festival, but misses the cut of 32 in the Grand Festival, causing him to leave Lake Valor to improve his training. Kenny is revealed to have romantic feelings towards Dawn and eventually challenges Ash to a battle with the outcome determining who Dawn would travel with. Though he wins the battle, Dawn leaves him a note stating that she wishes to remain with Ash.

Barry (ジュン Jun)
Barry is Ash's newest rival in Sinnoh, an impatient and overconfident boy who, while competent and skilled, tends to lose most of his battles against Ash. He is an admirer of Paul, and uses the same technique though he cares for his Pokémon. He dreams of being the strongest Pokémon trainer in the world. Barry is best friends with Kenny and the son of Palmer, the Tower Tycoon of Sinnoh's Frontier Brains. He is based on the rival in Pokémon Diamond and Pearl. He originally owns an Empoleon, a Staraptor, a Roserade and a Heracross and later gains a Hitmonlee and a Skarmory.

Nando (ナオシ Naoshi)
A talented Pokémon trainer and wandering minstrel, Nando is a calm young man deeply conflicted as to whether he should challenge gyms or become a Pokémon Coordinator. After battling both Ash and Dawn, he chooses to pursue both paths, regardless of the difficulty. By the time of the Sinnoh Grand Festival, he has acquired seven Gym Badges and five Contest Ribbons. In the Grand Festival, he is able to reach the Top 4, losing to Zoey. After the Grand Festival, he obtains the necessary badges to compete in the Sinnoh League; he is Ash's first opponent but is eliminated after putting up a good battle. Nando make his debut appearance in Dawn of a New Era!. He owns a Roserade (evolved from his Budew), a Sunflora, a Kricketune, an Altaria, a Kricketot, an Armaldo, and a Lopunny. He is usually seen playing his golden Mew harp. The harp has often been shown to attract large groups of wild Pokémon, although it is unknown if Nando is aware of this.

Angie (アオイ Aoi)
Angie is a girl who lives in Sinnoh. She was first seen in the episode when Ash, Brock, and Dawn, attended a Week-Long Summer School program for Pokémon Trainers. She showed her confident side by testing Monferno (as a test of the Summer Academy), telling it to hit her with Ember and Mach Punch. While doing so, she dodged the practice attacks and taunted Monferno, sparking frustration. The result was that its power grew, and it beat her up to the point of bruises, which she didn't mind. She served as the tomboyish rival/friend for Ash, even though she develops a friendship with him and had a crush on him later on.
When Angie hears of Ash telling about other Dimensions, She wonders if there are some worlds that are hostel and would invade, Ash thought of it long and hard, So He made Angie Second in command of The Ketchum Alliance for when he is not around.

Tobias (タクト Takuto)
An incredibly powerful trainer, Tobias is mysterious, silent, and unbelievably skilled, who apparently earned all eight of his gym badges only using his Darkrai. He competes in the Sinnoh League where, up until his battle with Ash, he manages to single-handedly defeat all of his opponents with just Darkrai. Ash battles him in the semi-finals, during which Darkrai ends up losing to Sceptile, only for him to send out Latios. Despite Latios' battle with Pikachu ending in a draw, Tobias still earns the victory losing only two Pokémon. He later wins the Sinnoh League with, once again, just his Darkrai. His only known Pokémon are Darkrai and Latios. He is arguably the most powerful rival Ash has ever faced.
After Ash was impressed with his skills, He offered to recruit Tobias into the Ketchum Alliance, Leaving some to question how the hell did he capture Darkrai and Latios in the first place.
