looks like someone from Marvel Cinematic Universe has become guest for Sora, Riku, Kairi, Donald, and Goofy (Kingdom Hearts); Ash, Misty, Tracey, and Melody (Pokemon anime); Robin, Starfire, Beast Boy, and Raven (original Teen Titans cartoon); Taichi, Yamato, Sora, Mimi, Koshiro, Joe, Takeru, and Hikari (Digimon); Recca, Domon, Fuko, Mikagami, and Koganei (Flame of Recca); and Isami, Toshi, and Soshi (Isami Shinsengumi), and he's Groot(sorry for making him looks like his baby self, this is my first time I ever drawing Groot in his teenage form)

Groot: I'am Groot!

Mimi: telepathically translates Groot he says Hello

Koganei: is that you Mokuren?

Groot: I'am Groot!

Mimi: telepathically translates Groot he says No!
