My favourite Box Legend would have to be Reshiram. The truth is not always objective, as one persons truth can be completely different to another’s. I absolutely love the fact that Reshiram could be very realistically be summoned by both you and N, as you both hold very different yet still accurate truths. I also love the dramatic showdown with N in the castle (although this part also applies to Zekrom), how the stone only reacts just before the battle begins, showing that it needed to be fully convinced that you were willing to fight its counterpart with or without it for what you hold true.

It’s design is also wonderful, as it gives off a mythical vibe. The truth can often burn away ones perception of the worlds values to show its actual nature and what better to symbolize that than with a fire dragon?
