Chara's soul was absorbed by Asriel in his grief when Chara killed themself. It's what allowed Asriel through the barrier to take Chara's body up to the Surface and ultimately be attacked by Humans, because they thought he killed Chara. Asriel made it back just in time to die in the castle, his ashes scattering over some golden flowers and causing them to absorb his essence. When Alphys experiments on these flowers with Determination you get Flowey and... well, we all know what happens next.

Ultimately, it was all part of Chara's plan to get ASGORE to wage war on mankind, screwed up little shit that they are.
