What is a esey way to fined LATIOS please help me?

It appears randomly sorry but there is no easy way to find him

Well you could use sweet sent,with that if you are at the location where it's at it might come to you.

Haha, ok, one of two ways, I restarted mine, I had like EVERYTHING but heres how I did it the first round. After it appeared to me the first time, I think I had already used my masterball or something, not sure, or I was still saving it for Rayquaza, but yea, either use the master ball the VERY first time it appears, trust me EASIEST, might as well get it done, and/or if you choose to save your masterball for Rayquaza, which is SMART, run around with a Wobbuffet or a Golbat as the first Pokemon that has the attribute that prevents a Pokemon from escaping. I also believe some Trapinch have that attribute. Anywho, make sure the Pokemon that you choose is no more then level 40. Then all you gotta do is check your pokedex to see where it's nesting and follow it until your in the same area, use a repel, but ONLY if your first Pokemon is no more then level 40, because it wont be repeled as long as thier the same level. Then run around in the grass or water and you should run into it. Use your masterball, or slowly wittle it's HPs down with each encounter. My advice is after each encounter save right after, just in case you accidently knock it out, you can restart and it's back. Once you've encountered it enough you should be able to get it asleep or paralyzed by switching out Pokemon, then catching it with an ultraball or something. But heres what i've learned. Just because Ultra and great balls claim to be better doesn't mean they will be. In other versions i've caught legendary Pokemon with normal pokeballs. So chyea. ;)
