In my incredibles au!the show goes on, there is a couple song(for each stage in my au) that I've found to define them all here they are(also their biggest fear/regret):
----------------------------------------------------------
Start(1954-1955):last words of a shooting star-mitski. (Felt a severe lack of purpose beyond raising his children and didn't really have anymore self preservation, which is why he went to syndrome's a Island he wasn't thinking straight.)
Middle(1956-1957):down by the water-PJ Harvey. (This is basically him feeling like he failed to protect his children especially when Ross and Rudolph joined a super team.)
End(1958-1959): never love an anchor-The crane wives. (Due to his fear of hurting his children, especially after he found out about the syndrome situation)
biggest regret: leaving Italy, going to syndrome's island not protecting Ross and Viktor.
Fear: losing and/or failing the people he loves, becoming his mother and mirrors.
----------------------------------------------------------
Rudolph(the green phoenix):
Start(1954-1955): harpy hare-Yaelokre. (When he found out Viktor and Ross were missing, his first thought was to go to his father and let’s just say it was not a pretty site)
Middle(1956-1957): Andrew in drag-the magnetic fields. (Straight up because he fell in love with Alix(gasleak) when he saw them drag.)
End(1958-1959): the Phoenix-fall out boys. (generally for the actual reason, his powers are being a Phoenix also when he was training Ross to be a hero after her villain stunt.)
Biggest regret: not taking Ross out of her spiral sooner, not asking Alix out sooner.
Biggest fear: losing his family(Simon, Ross, Alexander, Viktor and even though he doesn’t want to admit it his father Morgan), failing his team and water.
----------------------------------------------------------
Start(1954-1955): You're a big girl now-the stylistics.(first time she was ever truly on her own and looking after friends, the first time she was a "big girl")
Middle(1956-1957): seventeen going under-sam fender. (Right after she killed syndrome and Mirage, also during the time of her "villain" stunt(it was three months at most), then she proceeded to join Rudolph's team) 
End(1958-1959): 500 miles-Peter, Paul and Mary. (When she left America to Italy for the second time and then she left Italy and went to live in France with her girlfriend. She doesn't regret a thing but she does miss it.)
Biggest regret: going on her villain stunt for two-three months, going to the NSA(this girl hates the NSA)
Biggest fear: Pyrophobia, loud noise(possible relation to her deafness), water(will fry hear aids), her own powers, when family or friends are at risk(especially if because of her) and reflective surfaces.
----------------------------------------------------------
Start(1954-1955): Seasons in the sun-Black Box Recorder. (Just felt right, also describes his relationship with his dad)
Middle(1956-1957): made in Japan-Buck Owens and the Buckaroos.(yearning king final boss)
End(1958-1959): I'll believe in anything-Wolf Parade. (Yearning king final boss part two.)
Biggest regret: going to Syndrome's island, letting Ross go, not getting with Rowan(he lays awake thinking about him)
Biggest fear: heights, air vents(irrational phobia), arachnophobia very extreme, public speaking, public situations without people he knows and kids.
----------------------------------------------------------
Start(1954-1955): Fable-Gigi Perez.(internalized homophobia is a bitch) 
Middle(1956-1957): late nights & heartbreaks-Hannah Williams & the Affirmations.(he constantly feels like he failed Vikki.)
End(1958-1959): Can't catch me now-Olivia Rodrigo.(straight up disappears, they didn't catch nothing)
Biggest regret: staying with Vikki for so long and going to Syndrome's island.
Biggest fear: Loud noise, deep water, his mother finding out, Everseer and Syndrome.
----------------------------------------------------------
Start(1954-1955): Re-Do -Modern Baseball.(Idk it just felt right for some reason)
Middle(1956-1957): Late & Heartbreak-Hannah Williams & The Affirmations.(during the situationship arc be between him and Simon)
End(1958-1959): Earrings-Malcolm Todd.(When he finally got with Simon, pretty much the honeymoon stage)
Biggest regret: not getting with Simon sooner(dear Lord they make me sick),
biggest fear: losing/failing Macoburst(aka Mac), disease, dying and squirrels/rodents.
