Ero-Sennin Orochimaru
Mystery: They're mine!
Orochimaru gives a buff up to three Curse Mark shinobi on the team, granting them a 30% increase in ninjutsu, resistance, and attack as well as making them immune to debuffs that lasts for 1 turn.
Standard: Charming Snake
Attacks front row units that has a chance to cause chaos and knock-down.
Chase: Oh my..
Chases and attacks a knocked-down unit, causes knock-down and immobile.
Chase: Oh dear..
Triggered with atleast 30 combos, causes damage to 3 random units and has a chance to lower defense by 10%
Passive: Be one with me!
This unit's resistance and ninjutsu are increased by 20% for every Uchiha on the field.
Passive: Beautiful, aren't they?
This unit creates a shield for ninja with a 'Curse Mark' tag that's based off their resistance.
I don't know why, but I just imagine a creepily perverted Orochimaru who has a weird affection for his curse mark ninjas. His 'Oh my' chase would be him coiling around a target in a seductive manner, and the 'oh dear' basically being a group hug in white snake form.
