In the world, ฤทธิชา (ฤทธิชา 
, Ruethicha ) is a very rare predominantly male, but scarcely female first name. The first name ฤทธิชา is habitual in South-eastern Asia, particularly Thailand, where it is a very rare principally boy's, but scarcely girly name. Much less frequently, ฤทธิชา is the last name as well as the forename.
