Mimic

It is said "Imitation is the sincerest form of flattery". They obviously didn't meet the Mimic. A true copycat in her own right, she can learn an opponent's technique instantly and use it against them.

Appearance
The Mimic's attire seems rather plain at first, as it is only a form-fitting black bodysuit. However when using her copying abilities, the suit gains a colorful aura that gives her a see through version of the outfit that matches the Okuni she is copying.

Weakness
Despite having such an awesome ability, a Mimics can only use a technique at 80% the strength of the Okuni she copied it from. She also cannot copy abilities from creatures that aren't Okuni. She also cannot copy an Okuni's Special Ability.
