Adam's Greninja

This Greninja is a Water/Dark-type Pokémon that is owned by Adam and was the first Pokémon he obtained in the Kalos region.

Greninja is one of Adam's (if not the) most powerful Pokémon overall.

Personality
Greninja seems to be a tough and strict Pokémon in reference to his personality.

During his time at the breeding facility as a Froakie, he preferred to train alone instead of socializing with his kind.

Because of this, the other Froakie attacked and injured him.

After he was healed by Nurse Joy, he realized that in order to become strong, he need a trainer he could trust.

He ended up going through several trainers, but they all failed to live up to his standards.

He finally chose Adam after seeing his bravery and being shown love.

Greninja even has the tendency to blush when he is thanked and praised by other Pokémon and people.

For example, when he used its Frubbles to tidy up Fennekin's tail, she thanked Froakie for his thoughtfulness.

Greninja is also very protective towards others and is willing to keep them protected from harm.

For example, when everyone got separated after an attack from angry Pangoro, Frogadier stepped forth and protected Serena and Chespin.

One of Greninja's greatest insecurities was his close bond with Adam, as failing to perfect the Adam-Greninja form took a toll on both Adam and Greninja alike.

When Adam left Greninja in the Pokémon Center out of guilt for losing against Wulfric, Greninja gave chase to look for his trainer.

While Greninja was recovering from the battle, he also felt responsible for making Adam lose the battle.

However, after fully synchronizing their feelings to save a Spewpa from falling, Adam explained to Greninja why he chose to be a Pokémon master and he views Pokémon as friends.

After that, Greninja and Adam fully came to understand each other.

Greninja became a unique Pokémon of Adam after its hidden potential was unleashed; in its Adam-Greninja form, he gained considerably more power, endurance and speed.

Adam-Greninja has been very successful in helping Adam win his battles, with feats including overpowering Diantha's Mega Gardevoir, defeating Wulfric's Mega Abomasnow by slamming into the ice ceiling with Aerial Ace and easily defeating Tomo's Altaria with a single Water Shuriken.

He soundly defeated Sawyer's Mega Sceptile despite being at a type disadvantage, slicing through Sceptile's Frenzy Plant with Cut and overcoming he with a massive Water Shuriken, and went toe-to-toe with Alain's Mega Charizard X, an opponent that had once defeated 10 Mega-Evolved Pokémon in a row and went on par with a 50% Zygarde.

Before he joins with Adam while he was a Froakie, he is highly observant and a risk taker when he saves Pikachu when Jessie's Wobbuffet's Mirror Coat rebounded his Electro Ball against him.

In one episode, Greninja while he was still a Froakie has a short fierce rivalry with Adam's Hawlucha when they are not getting along during the double battle with both Clemont's Bunnelby and Chespin and they are usually seen arguing during Adam's special training of combining their moves.

But they later settle their difference after seeing Adam risking his life to save them from being hit on Trevenant's Will O Wisp and became best friends after they teamed up to stop Team Rocket's Pokémon.

Both Hawlucha and Froakie who is now evolved into a Frogadier team up against both Sawyer's Treecko and his Bagon.

Later, they play each other in the river stream and teaming up again to find the wild Eevee in both land and air but ends up in a failure until Will captures it. T

herefore, after evolving into Greninja, he and Hawlucha are seen doing some exercise during the break.

Aside from his strong friendship with Hawlucha, Greninja is another Pokémon who is briefly seen trying to stop Chespin and Pancham from fighting one another, seemingly aware of their rivalry.

Pikachu and Braixen are considered Greninja's other best friends as well as being very close friends with Talonflame, Goodra and Noivern.

At the start of A Fashionable Battle! and onward, Greninja while he was a Frogadier gains a friendly rivalry towards Sawyer's Treecko who is furious not to give up the fight after being hit from his Water Pulse twice and leading its evolution to Grovyle followed by Sceptile and its mega evolve form, Mega Sceptile.

Their long-standing rivalry was demonstrated during the 3 on 3 battles between Adam and Sawyer as their fight were equally matched and both of their Pokémon are seen either of the two will win or lose.

This also happens when both competed each other in the Kalos League Lumiose Conference.

Their rivalry soon ended where Adam defeats Sawyer at the semi-finals using Greninja as Adam-Greninja against Sceptile as Mega Sceptile.

Just like Sceptile, Buizel, Snivy and Hawlucha, Greninja is very cool, calm, collected and can get very serious when he comes to situations.
