2nd Gen Suicune

In Crystal, Suicune's role was expanded. It will roam around in the overworld, until it returns to the Tin Tower where you can catch it normally. Suicune kept its expanded role within the remakes, but it will appear somewhere else for you to capture it within the Kanto region instead.

What did you think of Suicune's expanded role within Pokemon Crystal?

That in-game event added some lore to one of my fave legendarys. Very cool.
