The first event includes reclaiming a Manaphy egg which was stolen by the Pokémon Pinchers. It is called 'Protect The Blue Sphere!' and can be played early in the game. When the egg hatches, the Manaphy will be at level 1.

The second event is called 'Deoxys and the Odd Temple', and is a multi-player mission. Only the host of the mission gets the Dexoys, which is at level 50 when sent over. The Forme of Deoxys which you receive depends on the time you take to capture it:

1 minute remaining = Normal Forme
1 to 3 minutes remaining = Speed Forme
3 to 5 minutes remaining = Defense Forme
At least 5 minutes remaining = Attack Forme (comes with an exclusive move, Meteor Mash)

The third and final event is called 'Investigate the Odd Eruption!', where you need to capture a Heatran in order to save tourists from a volcanic eruption. Heatran is at level 50 when sent over to another Pokémon game, and it knows the moves Eruption, Magma Storm, Earth Power and AncientPower.

EDIT: Shaymin mystery gift is out. It can change into it sky form. The event is called Rescue the Shaymin.
