What was team aqua and magma doing after the events of pokemon omega ruby and sapphire?

Team Aqua and Team Magma were still active as rival villain teams during the events of Pokémon Omega Ruby and Alpha Sapphire , but the games do not give them a big “afterward” storyline beyond that conflict. Their roles in Hoenn are focused on their opposing goals: Team Aqua wants to expand the sea, and Team Magma wants to expand the land, with Archie and Maxie leading those efforts.

What happened to them after

There isn’t a major canon update in Omega Ruby/Alpha Sapphire showing a brand-new postgame plan for either group. The story mainly treats them as still functioning organizations whose ambitions are stopped by the player, rather than teams that go on to a completely new phase immediately afterward.

In practice

• Team Aqua continues to appear as Archie’s group, pushing its ocean-expansion goal.

• Team Magma continues to appear as Maxie’s group, pushing its land-expansion goal.

• Their conflict is framed as ongoing rivalry inside the Hoenn storyline, not as a settled “what they did next” epilogue.

Simple read

So the safest answer is: they didn’t get a clearly defined new post-ORAS activity in the games themselves; they were simply defeated/stopped and remain known as Hoenn’s rival villain teams.

Quick scoop: there’s no official, detailed “after the events” mission for either team in Omega Ruby /Alpha Sapphire —just their same old ocean-vs- land conflict.

TL;DR: Team Aqua and Team Magma were still operating during ORAS, but the games don’t spell out a separate long-term plan after the main story; they’re basically left as Hoenn’s recurring rival organizations.
