Alright. There is so much confusion I'm just gonna spew facts now.
 * Jerry can delay the end of an attack.
 * Sans can do this indefinitely, somehow.
 * There are no buttons in the first Flowey encounter.
 * You never get your turn against Flowey, Omega Flowey, or Sans (after his special attack).
 * You do get your turn against Asriel.
 * Flowey's only known trait is determination.
 * You get your turn against Undyne the Undying also, and against the Amalgamates.
 * Asgore can attack the MERCY button.
 * Related to above and #3, the MERCY button is no longer provided at Genocide Asgore.
 * The only monsters to inflict unavoidable damage in a way clearly by choice are Omega Flowey, Asriel, and Sans.
