Bond Phenomenon

The is where a Pokémon can bond with its Trainer to activate an ability which is similar to Mega Evolution.
==History==
Not much known about this Ability, but according to Professor Sycamore, it said that the phenomenon once occurred several hundred years ago and rarely happens. When it does the mutual trust between Trainer and its Pokémon is high and they master it. Sycamore also noted that the phenomenon was related to the Pokémon's potential ability and it doesn't happen to just any Pokémon.
==Appearance==
===Ash-Greninja===
One example of the evolution is shown by Ash's Greninja. During the battle against Heidayu, Greninja's strong bond with Ash temporarily activates the Ash-Greninja phenomenon and allows them to defeat Bisharp before reverting to normal.
According to Clemont, when Ash and Greninja have resonated their feelings, Greninja's appearance will resemble Ash's. Serena even recalls Olympia had told them that Greninja will receive full power, which would prevail over greatness.
===Abilities===
In the games, the Bond Phenomenon is introduced in Generation VII as the Ability Battle Bond. When the Ability is activated, Greninja transforms into Ash-Greninja, increasing its Attack, Sp. Atk, and Speed stats, as well as making Water Shuriken more powerful.
In the anime, Trainer and Pokémon also share each other's point of view. In his second form, Ash's Greninja has a full form that can surpasses even the strongest Mega-Evolved Pokémon, even if it is a Pokémon that he has type disadvantage against, with the Water Fuma Shuriken on his back, which can deal massive damage to, if not defeat the strongest of his opponents in one hit, Greninja was able to defeat Mega Sceptile with just one hit from Water Fuma Shuriken; despite the fact that -type moves have little effect against -type Pokémon. It also turn his Cut attacks into blue kunai blades.
====Enhanced power====
Comparable to Mega evolution, the Pokémon's strength would leap in levels of power to the point of overpowering experienced Pokémon.
====Telepathic link====
Due to their connection, both trainer and Pokémon are able to communicate with their thoughts and share their sense of sight with one another.
==Weakness==
===Ash-Greninja===
Despite increasing Greninja's speed and power, it comes with the side-effect; if Greninja was attacked and takes damage, Ash will feel his pain as they shares each other's pulse, so if it is pushed too hard, Ash may collapse from exhaustion. It was soon revealed that the main reason why Ash and Greninja were having trouble with this form is because both of them didn't have complete faith and trust in each other. However, the other reasons they were having trouble perfecting this form is that Ash has a fear of losing any of his Pokémon for different reasons and Greninja was insecure of their close bond. After realizing how far they let their flaws get to them, Ash and Greninja resolved it as they made amends for their actions. After that, the weakness became more bearable for Ash as he maintains the pain whenever Greninja takes damage from an attack.
