So, here is a nice conspiracy theory / exercise in debate.
At the end of XY, Bonnie says to Zygarde that one day she will become a trainer, and will come and get him. Zygarde agrees. With Zygarde (and Dedenne) by her side, Bonnie would be unstoppable. Also, Zygarde has the ability to convince other Pokémon in the necessity of some actions, and make them help him. For this reason, it seems reasonable that if the cause was just enough, neutral/kind Pokémon like Celebii and Latios would agree to cooperate with Zygarde. Darkrai is slightly more evil, in my idea, but I'm sure that with Latios and Zygarde, he would be conquerable. Zygarde knows that Ash's and his Grenninja's help in the Kalos conflict is aboslutely necessary. Now, if Ash, for some reason, would not be around Kalos at that time, then things would be rather bad. Looking back on history, Zygarde realizes that there was such opportunity, when Ash was at Sinnoh league (which many fans consider to be his best or second best (after Kalos) league). If Ash won that, he might not have gotten to Kalos at all, and that would be bad. Zygarde must make sure that Ash will lose in Sinnoh. The obvious solution is to travel back in time, register Bonnie to the Sinnoh league, and had her beat Ash. This is also consistent with Bonnie's desire to fight Ash when she will be a trainer, and fighting Sinnoh-Ash would be one of the greater challanges she could ask for. Bonnie masquarades as "Tobias", so that Ash will not recognize her when he gets to Kalos, and change his behavior, obviously.
And from there - everything is history. Bonnie/Tobias hammers Ash, causing him to lose, and move on to Unova. Why did she not intervene in Unova? Maybe because Zygarde realized Ash would have lost there anyway, and he did not need to intervene. After all, Zygarde is aware of the results of those leagues already, as they did already happen. This gives us the motivation, and a means to place Bonnie in the finals of Sinnoh league. Therefore, Tobias = Bonnie is an inevtiable fact (barring the fact that they look nothing alike, but hey, who knows how Bonnie will look like when she grows, eh?). This would imply that Tobias' team is Darkrai, Latios, Zygarde, Celebi, Dedene, and one more Pokemon. Maybe the Heatran from the opening ceremony episode? Doesn't matter really. After the did was done, it is entirely reasonable that Bonnie freed the legendaries, since holding them was no longer necessary (unless they wanted to stay with Bonnie - I guess that's also technically possible).
The only downside of this theory is that it requires a stable time loop. Other than that - you are cordially invited to attack and destroy this theory from all possible directions, but I think it will be a nice exercise in debate :}
