Game-Breaker: Biological class happens to have one when the player combines Predator Form, Toxicant Form, Shadow Blend, Crystallize, Agile Exposure, and most importantly, Withdrawal. Almost always kills the victim in one shot of Withdrawal.
An Electric Psychological can be very powerful. The bread and butter spell of the build, Shock Therapy, not only deals heavy damage but also removes buffs from enemies, and Electric Storm restores the Focus you waste on Shocking right back. There's also a skill providing a substantial passive increase for Electric damage, and Wraith Form gives so much speed that almost every spell crits for massive damage. In addition, weapons providing massive boosts to electric damage are everywhere, as opposed to weapons with boosts to dark damage, which are very few and far between (and none at all in the endgame). The Achilles' Heel of a Psychological is the health, but the Force of Will shield and the aforementioned Wraith Form speed boost will take care of that - most enemy attacks miss and those that hit get absorbed. Putting enough points into the dark spec to achieve Psychopath form results in incredible pain for the enemies if you assume both forms at once.
For those who just want to cheese bosses, hit them with High Voltage twice, which doubles their healing taken, then two shock comas (each healing them for 12% of their max health per turn), then another High Voltage. This combo means that for the next 2 turns, the boss will heal for over 100% of their max health. Now reverse healing and damage with Retrograde and watch the boss promptly die, after having exactly 2 turns to do anything.
Goddamned Bats: Potentially every enemy on higher difficulty levels. The monsters have just as many tricky spells as you do, and even a pair of lowly prison guards can keep one of your characters stun-locked for the entire battle. And that's not getting into all the healing and ablative shields being thrown around...
In Sonny 1, only your Guest-Star Party MemberLightning Bruiser can do enough damage to get the Baron's HP down to 0 in anywhere under 100 turns, which means that Sonny and Veradux are pretty much stuck with the jobs of keeping him healthy and helping him do more damage. Then you get Player Punched when said Guest-Star Party Member becomes the Final Bossin the very next fight (thankfully he's not hitting for thousands upon thousands of damage anymore).
He's even worse in Sonny 2. First of all, you don't get a Guest-Star Party Member to help you. Furthermore, the Baron has some very annoying new tricks. First and foremost among these is Tick Tock, a debuff which lasts for 10 turns, takes away 10% of the victim's life every turn, and reduces all healing done to them by 50%.And it can't be dispelled. And just to make this worse, Baron Brixius loves to use it as much as he can... which is about every 6 turns. And he has just as much health as he did the last time (48,269... and that's in the easy mode.) Your only hope is to whittle down the Baron's Focus to nothing in order to force him to use Deep Burning, a move which fully restores his Focus at the cost of about 10% of his life.note Note that he has access to Electrical Storm, which regenerates his Focus. And once he can no longer use Deep Burning, he starts wasting his turns with actions which do nothing but weaken him. Good luck getting him to that point, though - unless you've maxed out Disrupt (a move that you can only get with the Biological class,) you'll need it.note Oh, and just to insult you, Baron Brixius is an imitation of Tim Curry, and the epitome of Ambiguously Gay. Who the hell is his voice actor?!
The electric robot birds in the Electric Zone are extremely fast, and they gain power whenever they dodge an attack.
The Plague Assassins in the sixth zone are Gradual GrinderFragile Speedsters that can attack almost twice as much as any of your characters, spams an attack that reduces your hit chance, and gains power every time he dodges your attacks. Clearly he wasn't meant to be a fun experience.
First of all, one of the Frost Strain's strongest abilities is Frost Charge, which heals the user, restores 100 Focus, reduces the cooldown of the previously used ability by five turns, and grants Clarity (increases critical strike chance for one turn). These characteristics are all extremely powerful, but the game-breaking part comes from the Mutation system. If you evolve Frost Charge with Diffusion, then Frost Charge will restore health and focus for all allies while reducing the cooldowns of the user's previous ability and the Frost Charge ability, creating an infinite loop of damage and healing. This can be combined with Kara's EMP Blast (deals heavy damage to all enemies while draining 100 focus from each enemy) for even more power. However, the Mutation system relies on luck, and the upgraded Frost Charge becomes less effective if an ally falls in battle.
The Ice Wall ability is, quite frankly, complete bullshit. It stuns the entire enemy party for two turns, letting you wail on them to your heart's content. Technically speaking, it does also increase their defense by 300%... but that's worthless when you have attacks that ignore defense entirely, such as Sonny's Drill Strike, Dr. Herregods' Eco Strike, and Kara's Shadow Blade (and basic attacks, courtesy of armor piercing weapons). It can also be combined with Sonny's Break, Snap Kick, and the aforementioned Frost Charge to cause a total party stunlock for the poor bastards on the other side of the battlefield. The only enemies capable of standing up to you at this point are Templar Arcanis and the ZPCI Praetor (who have stun resistance) and Baroness Marie and Dr. Klima (who reflect some of your damage back at you).
Porting Disaster: The iOS and PC ports certainly look better than the original flash games, but they also removed all animations as well as 90% of the voices, which was one of the main draws and most liked aspects of the originals.
To be fair, the reboot has significantly more dialogue than the original games, so the difference between the amount of voice-acted dialogue in the flash games and in the reboot is actually very small, if not nonexistent.
That One Attack: When you finally fight Captain Vendara for real, he uses an extremely irritating combination where he will 1. use Frost Nova to empty your entire party's Focus and slow them down by 35%, 2. use Scatter Shot to empty your entire party's Focus AGAIN, and 3. attack and kill someone. God help you if he is able to outspeed you.
