When Greninja was a Froakie, he was very playful and friendly. As Bloom saved his life, Froakie was very grateful and started to bond with her. However, when Kommissar helped Equestrian Empire warriors to stop The Chaos Lords and later evolves into Frogadier, a tension started to go in between them. Since he evolved into Frogadier, he became docile, calm, and more focused on completing his tasks. During Bloom's absence, he believed that Bloom responded him and taking care for him ever since she saved him. Nevertheless, when Bloom defended Frogadier from King Sombra, he realized the error of his misunderstandings and regained his trust for Bloom. Greninja is also shown to be loyal and always wanted to be with Bloom after the years of teaming up, which gave Komissar General Bloom the opportunity to catch him so they'll be together once more.
Like Piggy and Totodile, Greninja is very cool, calm, collected and can get very serious when he comes to situations.
