i haven't beaten all of zone 4 but i have gotten to the last boss. here are some tips for each of its bosses:
Ignition: This guy mainly requires a lot of luck since he has the really powerful ability. just try to keep your guys alive and deal as much damage as possible.
The Samurai Dude: i don't remember his exact name, but i beat him in one try every time. he has a lot of health, but bad attacks. basically the trick is to do as much damage as possible. when he uses a move on himself that says that "he will do lots of damage next turn but is taking a lot more damage this turn," attack him with break. it will do a lot of damage and stun him, so he will not be able to use his extra powerful attack next turn.
Doctor Heregods: Don't be intimidated by the fact that he has 1,000,000 health. if you do exactly what i say you will defeat him no problem. the key to this battle is the move "subversion." make sure you have this. now start attacking him. keep attacking him until right when he is about to get under 1,000,000 health. when he has just under 1,000,000 health, put subversion on him. he will heal for 2,000,000 health. but if you put subversion on him before he heals, he will do 2,000,000 damage to himself, killing him instantly. if you don't do this the battle will go on forever since he will just kep doing huge heals everytime his health is under 1,000,000.
Sinjid: I still haven't beaten him. really hard. but i know the trick to this battle. use corruption. everytime he has 100 focus he will use his most powerful attack which kills instantly and almost never misses. make sure to use corruption on him before he uses it and you will make him lose some focus. i think that if you can do good damage on him and keep him from using that move then you will eventually win.
for sonny 1 there is a cheat/glitch where you bring your items to the settings menu and drop them there.... what will happen is that all of the atibutes of that item will be put on sonny (the character)

The Samurai is called Omen. He uses a move called Dark Omen.
You do not use a move called corruption. The move is called disruption. Corruption is a move in Sonny 2, not Sonny.
