For those of you who are having trouble with any bosses or any notable enemies, you are reading the right guide (I hope). This is a guide designed for people who are having trouble with any of the classes battles in Sonny 2 (meaning this is for all classes; Hydraulic, Biological, Psychological).
My Builds were:
1. Cold Hydraulic
2. Psycho Shocker
3. Brute Biological
Let's get going, shall we?
--------------------------------------------------------------------
Felecity (Zone 1, New Alcatraz)
Some say she's hard, as a boss. Of course, bosses are supposed to be hard, right? WRONG! Bosses can be defeated easily, with the right strategy, of course. Felecity doesn't require a strategy, although you may have to be careful from her Black Metal de-buff.
For Hydraulics: She is still hard, but it the de-buff above can be stopped, because you have a Freeze combo (consisting of Mind Freeze 4/4, and Flash Freeze 4/4). This is useful because if you use Mind Freeze, the only she can use is her pitiful Leading Strike. Keep using the combo until she gives you the tape.
For Biological: This still can be a hard battle, because Biologicals don't have a Mind Freeze or Flash Freeze of some sort. I'm just going to say it, but there is no strategy. But the abilities you should get is:
Integrity
Break
Vicious Strike
Integrity gives you both HP and Focus, and if you have at full 4/4, it restores 3% health and 25 focus. Break is useful, somewhat. It gets her stunned for one round. Vicious Strike is also useful because it heals you if you use it.
For Psychological: There is no strategy required, although you should get Electrical Storm, Shock Therapy, and Dark Echoes. Equip them all to their maximum use on the action bar. Use this combo:
1. Dark Echoes, Electrical Storm, Shock Therapy
This should work, since it did for me
--------------------------------------------------------------------
Baron Brixius (Zone 2, Oberusel)
People say he is hard. I laugh in their face, because I say he is one of the most notably easiest boss, EVER. Let's get the cheap stuff around, shall we?
For Hydraulics: There is no way to drain his focus, although you should have full Ice Wall, Flash Freeze, and Mind Freeze. Ice Wall is good because in case he ever casts Tick-Tock on anyone, it's good just for that because it lowers damage done on you. Flash Freeze can be good because, well, it just stuns him. Mind Freeze, I cast it whenever he uses his deep burning move, so he can't use Tick-Tock while his Deep Burning move is activated, because even if you did lower his focus, it's all 100 focus. So ya, all he can use it Electrical Storm, which restores focus to him, but he already has 100 focus! So use this combo:
Flash Freeze (every 2nd turn), Mind Freeze (every 10th turn)
---------------------------------------------------------------------
Captain Hunt & ZPCI Sniper and Medic (Zone 2, Oberusel)
These guys maybe the hardest boss, ever. Because the sniper has 2 buffs which allow him to hit this awful criticals. What did I do?
For Hydraulics: Use everything you got on the Sniper. Same old Freeze Combo. But Captain Hunt can be bit of a bugger sometimes, so I also have Ice Wall in my action bar. I use Ice Wall when someone on the team gets low on HP, then I put both of my team mates on Phalanx so they could heal up. Roald's Greater Purpose and Ice Wall combined on any character, when hit, only hits one damage. It's useful. When you take out the sniper, take the medic. Then Captain Hunt.
For Biological: This maybe a bit easier, since you are stronger in physical combat. As I said before, take out the sniper. First, use destroy. Then Wound. But when he uses his Lock and Load buff, use Break, and hope that was the first buff he used, because Lock and Load lasts for two turns. When you take him out, take the Medic, and Captain Hunt. It's okay for Roald to die before you take out the Medic.
For Psychological: This can be hard, but make sure you have Shock Therapy, Electrical Storm, Dark Echoes, and you may also want Wraith Form, because it enhances your speed and damage, which are important for Psychologicals. Whenever he uses his Lock and Load and Crouch buff, uses Shock Therapy, as it dispels his buffs. Use Wraith form, whenever you can, as it can cause massive damage whenever you cast any spell.
---------------------------------------------------------------------
Gregor (Zone 4, Labyrinth: Tunnel of Illusions)
OMG, this freakin' bug, well, bugs me. This is an easier battle both for Hydraulics and Biologicals, but is hell for Psychologicals. I shall explain.
For Hydraulics: This is so easy. Just use the Freeze Combo on him, Mind Freeze (when it runs out, ---> Flash Freeze (when it runs out ---> Mind Freeze (when it runs out ---> Flash Freeze, then repeat.
For Biologicals: This is a bit more difficult, but not at all. Just have a 2/2 Disrupt handy, and maybe a Destroy. Keep on using Disrupt, and keep Veradux and Roald on Relentless, and in no time, he will be dead.
For Psychological: I just barely made out of this one. For Psychological, you may want Traumatize, Dark Echoes, Electrical Storm, Shock Therapy, and Dark Echoes handy. Also have Wraith form. When Gregor uses Roach Vitality, wait it out, then use Traumatize. The pour out everything you got , until his stun runs out. Use it again, then pour out everything you got. And use Wraith form whenever possible. In a lot of time, he is dead.
---------------------------------------------------------------------
The Hydra and Fire Claws (Zone 4, Labyrinth: Tunnel of Illusions)
This battle did not give a problem, except I died so many times because of Envenom from the Hydra, so you may want to be careful. The Fire Claws are easy, although the Hydra is difficult. Here we go.
For Hydraulics: Beating them all was easy, only because Fire Claws are super weak to Vapour Cannon, so use it against the Fire Claws. Once beaten, focus on the Hydra. Use the Freeze Combo, same old thing. All he will do is replenish his focus, as that is the only move he can use.
For Biologicals: Not even a problem. Fire Claws are super weak to poison attacks, so you may have to re-spec for this battle. Get all the poison attacks, such as Envenom, Infect, Anesthetic, and you will need Toxicant Form. Toxicant form replenishes 20% of your health, and increases your poison piercing. Use the poison attacks against the Fire Claws, but then don't even bother using the poison attacks against the Hydra, as he is super immune to poison attacks. Just use your normal attacks, Leading Strike and Destroy.
For Psychologicals: This is somewhat an easy battle, because Fire Claws are super weak against electric attacks. So have a Shock Therapy and Electrical Storm handy. And a Wraith Form. Then you have everything from there. Just keep watch of the poison de-buffs.
---------------------------------------------------------------------
Specialists and Android Guards (Zone 5, Hew: The Dystopia)
There are many of these in this Zone. They usually come in pairs of two, but then there is one occasion where there is one Specialist and two Android Guards. Android Guards are the body-bags in this situation. But the Specialist is the stronger one, except he has extremely low HP, so you might want to go for him first. Then focus on the Android Guard(s) after he's dead. There is no strategy required for this type of battles.
---------------------------------------------------------------------
Police Colonel (Zone 5: Hew, The Dystopia)
This guy is some what hard, because he has a buff which allows him to deal hard, critical hits. When ever he does, here's what to do:
For Hydraulics: You may just want Flash Freeze. Because he uses this buff where he glows orange (I forgot the name, lol). In this case, you might want Flash Freeze him. Then usually he shoots a red bolt when the glow wears off, then it will lead right where you want him to be (glowing blue), which is a de-buff called Reloading. When he does, shoot out everything you have at him. Repeat when glows orange, then blue.
For Biologicals: Not easier, because you don't have 2 turn stun move, and all you have is break. So, use it on the last turn of the buff, then when he glows blue, pour everything you got. Basically, all you need is Break, Leading Strike, and Destroy. Easy as that.
For Psychologicals: Easier, because you can use Traumatize to wear off his glowing-orange buff, then when he glows blue, use everything. Same thing.
---------------------------------------------------------------------
Mayor (Zone 5, Hew: The Dystopia)
No strategy required, although take out the Guardian Cannon first, because he can be a pest. Once he is done for, take out the Mayor. Easy as that.

There you go. That's my guide. Pretty short. If you like more information (like how to beat the 4 Zone 6 units), feel free to ask.
Thanks.
