Chiyome gains a Fire Sub-Attribute and +100 HP, +50 ATK, and +30 RCV at max level. (seems like they're really trying to drive home her Balanced type with these stat gains.) LS: 2x HP and 2.5x ATK to Balanced type monsters.
Fuma Kotaro gains a Light Sub-Attribute and +500 HP at max level. LS: 2x ATK/1.5x HP and RCV to Physical type monsters.
Hanzo gains a Dark Sub-Attribute and +150 ATK at max level. LS: 2x ATK/1.5x HP and RCV to Attacker type monsters.
CAD gains a Fire Sub-Attribute, Physical Sub-Type, and +800 HP at max level. LS: Decrease damage from Water att. enemies by 55%.
Skill Buffs:
Hydra's Poison will be buffed from 5x ATK in Poison damage each turn to 10x ATK in Poison damage each turn.
All single-color Orb Enhance skills (Enhanced Fire Orbs, Enhanced Water Orbs, Enhanced Wood Orbs, Enhanced Light Orbs, and Enhanced Dark Orbs) will have their max CD reduced from 10 turns to 5 turns.
EDIT: Something random also added to the JP version:
It is a Light attribute Enhance Material monster with 832 in every stat. He gives 83200 EXP when fed to a monster, his Active Skill heals you by 832 HP, and his Leader Skill is interesting: It's 3.5x ATK to Enhance Material monsters. Too bad none of the Enhance Materials have high ATK...
