While I quite like the artwork (and I think they potrayed Taiki pretty well), I don't really like that they put Taichi from Tri. They artwork is meant to show us all of the google boys and the main protagonists. But is Taichi from Tri really the main character and a google boy? To be honest I can't tell who among the kids in Tri is the main character, but if I had to choose someone, I would choose either Koushirou or Takeru. Koushirou because in Tri pretty much he's the one that moves the storyline forward, and Takeru because he's the link between Adventure, Zero Two, and Tri (and unlike Hikari, he had much more screentime and been shown to have a rather mischievous sense of humour - and he is the character that changed the most in the series (from a crybaby, and super serious character to a mischievous devil)). And this why on that artwork we would have just two Agumons instead of three.
