Is it possible to change Deerling's form in later generations?

Question

Or is it impossible outside of Gen 5, as seasons did not return?

Comments

That's a pretty good question, actually. I'm fairly certain I've heard about Deerling's form being able to change in Gen 6 onward, but I can't remember how it happens.

Answer 1

Deerling changes its appearance depending on the current season. However, this change in form does not occur after capture, unless it is present in the player's party at the time of a season change. This applies to Eggs as well.

When the month is January, May, or September, the season is Spring, and it becomes Spring Form.
When the month is February, June, or October, the season is Summer, and it becomes Summer Form.
When the month is March, July, or November, the season is Autumn, and it becomes Autumn Form.
When the month is April, August, or December, the season is Winter, and it becomes Winter Form.

From Generation VI onwards, Deerling can be bred in any form at any time if the parent is of that form
