Kempo
Kenpo (or Kempo), which is sometimes referred to as Kenpo Karate, is not actually a strict Karate lineage. It's most noteworthy practitioner, Ed Parker, whom many trace a lineage from, actually studied a modern hybrid martial art he learned within the Unites States, which combined elements of Judo, boxing, and Chinese martial arts, among others. Due to its similarity in the usage of striking methods, forms or Kata, and techniques, it is sometimes referred to as Karate to aid with understanding and promotion in the USA.
