How to catch latios and latias

[Asppirhyne]

Hello, i followed the quest for latios and latias, but when fighting them i couldn't throw a ball because it was a boss fight, now what ? can i refind them and catch them or it's only for pokedex entry ?

 

All the quests wiki i found stopped there saying about low catchrate so i'm worried.

 

Thanks for help

Hello @Asppirhyne. 

 

During the quest, you will be tasked with battling both Latias and Latios in their Mega form.

Can you provide a screenshot of what the TV in Littleroot Town says?

Hello @Epithet,

 

I only fought them in their normal form.

The wikis being quite old all the images are now corrupted 

 

Thanks for your help

Hello, 

 

It appears you do not meet the requirements needed to do the Latios & Latias quest. One of the requirements is having all non-legendary Hoenn caught data, which you are missing quite a lot of.

Once you meet those requirements, you can do the quest and catch your pick of two. Here is a guide to the quest, which also outlines the requirements needed.

Let me know if you have further questions.
