>No human antagonists, or at least none that interfere with this plot point>Big bad is the box legend itself>This hypothetical pokemon would be feared and dreaded in the story>Known to have caused disasters and havoc before, gives a sense of looming danger in the story>Starts running amok again, not caused by being awakened/controlled by some stupid evil team leader>Damage is actually shows in the overworld (maybe ruins a city or something, idk)>It's up to the player (and maybe rival) to beat it>You don't catch it at first, just defeat it battle>It's like a totem boss in that it's strong enough to contest with your whole party by itself>Bigger disaster averted when beaten, but not gone for good>Post-game gives opportunity for player to finally catch it, effectively getting rid of the danger once and for all
