Humanoid Bosses (most information taken from various GameFAQs guides)
Sora's Average Damage: Damage: 1 Combo = ~20
Axel 1
320 HP
Weakness: Ice
Absorbs: Fire
Nullifies: Gravity
Speed: High (skips many turns, but that's his AI)
Attacks:
Slash - Low damage, usually about 3 hits.
Blade Blink - Low-medium damage
Fire Wall (sleight) - Low-medium damage (Multi-Target) (Fire)
Teleport (doesn't use a card or a turn)
Comment: Off the top of my head the damage was pathetic. Second form blows this one out of the water. Puny
Now that I think about it, he's probably a Low Light. His damage is more like 10-14HKO.
Cloud
275-375 HP
Weakness: None
Absorbs: None
Nullifies: Gravity
Speed: High
Attacks:
Attack - Medium damage
Cross-Slash (sleight) - Medium-high damage
Omnislash (sleight) - High damage
Comment: Surprisngly solid for such an early game boss. Omnislash is a pain in the ass, but he doesn't have a whole lot else. Not that he needs it however. High Middle.
Hades (a.k.a. Sir Overpowered A Lot)
440-600 HP
Weakness: Ice
Absorbs: Fire
Nullifies: Gravity
Speed: Very high
Attacks:
Fire Poke - Low-medium damage (Fire)
Fire Bash - Medium damage (Fire)
Temper Flare (sleight) (enters Temper Flare mode) (stays in Temper Flare mode for a certain number of attacks around 30)
------
Flamethrower (Normal attack in Temper Flare mode) - High damage (Fire)
Firaga Ball (sleight) (must be in Temper Flare mode) - Very high damage (Fire)
Comment: He's pretty mean normally, but Temper Flare mode is just insane. Flamethrower rapes with it's quick speed and decent damage, and alternatively Fiarga Ball is around 2HKO. His durability is pretty good too. He's like Rubicante with a tiny bit less durability and damage in exchange for mountains of extra speed. High Heavy.
Larxene 1
1120 HP
Weakness: Special attacks
Absorbs: None
Nullifies: Gravity, Thunder
Speed: Second Game's best (you'll never guess who's first!)
Attacks:
Feral Slash - Low damage; 3(?) * 2 hits = 6
Flick - Low damage; 5-6(?)
Thunder - Low-medium damage (Thunder) (Multi-Target); 8-10(?)
Lightning Bolt (sleight) - Low-medium damage (binds opponent during attack) (Stuns for about two turns after attack, but getting hit ends the stun) (Thunder); 3(?) * 3-4
Teleport (doesn't use a card or a turn)
Comment: Nice HP, and probably the (second) fastest in the game. Pretty much doubles anyone. Too bad her damage is pitiful. Her second form doesn't fare much better, but this form doesn't really kill anyone. Puny to Low Light.
Riku Replica 1
1120 HP
Weakness: None
Absorbs: None
Nullifies: Gravity. Resists every element.
Speed: Above average
Attacks:
Hop Bash - Low to Low-Medium damage; 5-10
Slash - Medium damage; 15-20
X-Slash - Medium damage (Stuns for about two turns, but stun ends when hit); 20
Shadow (Raises value of cards by two)
Sora Level: 29
Sora HP: 245
Comment: Damage is better than Larxene's, but not by much. Speed is above average. High Light
Riku Replica 2
1120 HP
Weakness: None
Absorbs: None
Nullifies: Gravity. Resists every element.
Speed: Above average
Attacks:
Hop Bash - Low-medium damage
Slash - Medium damage
X-Slash - Medium damage (Stuns for about two turns, but stun ends when hit)
Dark Firaga (sleight) - Medium damage
Shadow (Raises value of cards by two)
Comment: Same HP (the number may be wrong actually though), as well as same everything else, but Dark Fiarga (which is NOT Fire based) is a nice add-on. Now he's more of a Low Middle.
Captain Hook
640-760 HP
Weakness: None
Absorbs: None
Nullifies: Gravity, Thunder
Speed: Average
Attacks:
Slash - Medium-high damage
Ticking Gift - High damage (explodes a couple seconds after being thrown) (Throws Hook off balance for about two seconds)
Rush & Present (sleight) - Very high damage
Combo & Present (sleight) - High damage (Multi-Target)
Hook - Second Chance enemy effect
Comment: HP is rather sad, but awesome damage. Second chance is very nice too. Not very versatile though. Still a good Heavy.
Vexen 1
1120 HP
Weakness: Fire
Absorbs: Ice
Nullifies: Gravity, frontal physical attacks
Speed: Tiny bit below-average
Attacks:
Shield Strike - Medium damage
Blizzard - Low-medium damage (Ice)
Freeze (sleight) - No damage (Freezes enemy for 2-3 turns, or until hit) (Ice, though it having an element at all is irrelevent)
Blue Rhapsody - Blizzard Boost enemy effect
Teleport (doesn't use a card or a turn)
Comment: Nothing special. Weakness to Fire hurts, and who really uses Ice nowadays? Not being able to attack from the front can be frusturating, but I'm not sure how that translates to the DL. Seems to fit in perfectly in Middle.
Vexen 2
1120 HP
Weakness: Fire
Absorbs: Ice
Nullifies: Gravity, frontal physical attacks
Speed: Average, maybe a bit above average
Attacks:
Shield Strike - Medium damage
Blizzard - Low-medium damage (Ice)
Freeze (sleight) - No damage (Freezes enemy for 2-3 turns, or until hit) (Ice, though it having an element at all is irrelevent)
Iceburn (sleight) - No damage (Creates patches of ice around the battlefield, that when walked on, make you slip and become defenseless for about two turns (or until you're hit of course)) (Ice, but again, element is irrelevent)
Diamond Dust (sleight) - Continuous low damage for around three turns (Multi-Target) (Ice)
Blue Rhapsody - Blizzard Boost enemy effect
Teleport (doesn't use a card or a turn)
Comment: Faster, and Diamond Dust is a small bit of help. A solid Middle.
Riku Replica 3
1120 HP
Weakness: None
Absorbs: None
Nullifies: Gravity. Resists every element.
Speed: High
Attacks:
Hop Bash - Medium damage
Slash - High-medium damage
X-Slash - High-medium damage (Stuns for about two turns, but stun ends when hit)
Dark Firaga (sleight) - High-medium damage
Shadow (Raises value of cards by two)
Comment: Little has changed, yet he's much better than before. First off he's faster. Second he does decent damage now. No new sleights, but still a High Middle or Low Heavy.
Riku Replica 4
1680 HP
Weakness: None
Absorbs: None
Nullifies: Gravity. Resists every element.
Speed: Higher than last time
Attacks:
Hop Bash - Medium damage
Slash - High-medium damage
X-Slash - High-medium damage (Stuns for about two turns, but stun ends when hit)
Dark Firaga (sleight) - High-medium damage
Dark Aura (sleight) - Very VERY high damage (confuses opponent at end)
Shadow (Raises value of cards by two)
Comment: Insane. HP is nice and high, faster than ever, better damage than before, and Dark Aura which is about 2HKO (which is damn impressive by this game's standards). Not sure if he's got the oomph to win in (Low) Godlike, but he'd be a damn fearsome High Heavy.
Larxene 2
1680 HP
Weakness: Special attacks
Absorbs: None
Nullifies: Gravity, Thunder
Speed: Game's best
Attacks:
Feral Slash - Medium-high damage (fast enough to combo around four or five of these together in a turn)
Flick - Medium-high damage
Thunder - Medium-high damage (Thunder)
Lightning Bolt (sleight) - Low-medium to medium damage (binds opponent during attack) (Stuns for about two turns after attack, but getting hit ends the stun) (Thunder)
Teleport Rush (sleight) - High damage
Teleport (doesn't use a card or a turn)
Comment: Talk about upgrade. I was wrong about the damage not getting much better for this form. Feral Slash is not only powerful, but fast enough to have her use about four in one turn. That's like 12 slashes of pain. Teleport Rush is just murder. Not dependant on Thunder either. I don't think it would be too much of a stretch to say Low Godlike.
Axel 2
1680 HP
Weakness: Ice
Absorbs: Fire
Nullifies: Gravity
Speed: Very High
Attacks:
Slash - High damage (Can combo about three into each other for big damage)
Blade Blink - High damage
Fire Wall (sleight) - High damage (Multi-Target) (Fire)
Firetooth (sleight) - Very VERY high damage (Multi-Target) (Fire)
Teleport (doesn't use a card or a turn)
Comment: Huge jump as well. Organization members can be scary when they try. Slash does insane damage when comboed together, making even Feral Slash combo seem average. Firetooth is almost overkill. Not entirely reliant on Fire either. Godlike
Marluxia Replica (Technically not the real Marluxia, though you may as well count them as the same person)
2240 HP
Weakness: Physical attacks
Absorbs: None
Nullifies: Gravity. Resists Fire, Ice, Thunder, and special attacks
Speed: Above Average
Attacks:
Phantasmal Slash - Very VERY High Damage (Kind of has to skip the second turn because of how slow it is)
Shockwave - High damage (Multi-Target)
Air Cleaver - Very High damage
Blossom Shower (sleight) - High damage (Multi-Target)
Deathscythe (sleight) - Very VERY high damage
Marluxia - Double Sleight enemy effect
Comment: Insane. Huge HP, resistance to all magic and sleights, godly damage, only weakness is gets owned to hell by a fast melee. High Godlike
Marluxia's final form is inferior, so forget that. >_>
More later, as well as average damages maybe.
Riku mode bosses coming soon.
