An information gathering and assassination focused Shinobi, he infiltrates through possession & transformation, marks locations with Raijin seals for later infil/exfiltration and places observatory seals to listen in and watch top secret locales. He mind-raids targets for the information he can't otherwise steal and often times will even remove himself from his targets memory afterwards.  When assassinating others, he tries to do so while in possession of a trusted aide or colleague.

As an overview, his primary gimmicks are memory manipulation/possession as well as Seals. He uses Seals for everything from Sealing enemies, to laying traps through stored jutsu. He is particularly fond of Clones & Substitutions, and having them either explode (Paper Bomb Clone) or Trap enemies (Earth Clone + Sealing Tags) or even Mind-Puppet Switch Technique.

He intersperses Genjutsu, Taijutsu and Ninjutsu as required during battle, having a large arsenal to choose from having raided the minds of dozens of shinobi over the years.

Whenever possible, he will seek to fight having already possessed an ally of his enemy, or bystander, then Transform to look like himself. In this way, even if he is defeated he can end the Possession and return to his real form unharmed. Because of this and the fact he wears a mask, his "real" identity is a subject of conjecture.
