Idea: During the inevitable confrontation between the good Avatars and the extended Union, Andrew actually shatters Olimar's helmet, by this point knowing full well what the oxygen would do to him, and what happens when an Avatar dies. Even the rogue avatars are shocked by this(except Ramagog because he's evil) because really!? You'd doom an entire universe just because your kid found a better father than you?
This'd probably happen due to him snapping after the reveal that Tulip ran away long before becoming an Avatar, and Olimar jumping in to defend her from him again.
Thankfully Olimar survives thanks to an experimental emergency atmosphere filter Alph installed in his suit for testing purposes, but nobody knew it was there at the time.
