In anime, manga and games, any characters who launch an attack shout the name of the attack/defense.
The list is long, just a little sample :
Dragon Ball : Kamehameha !
St Seiya : Pegasus Ryuseiken ! (Seiya attack)
Dragon Quest : Raiden ! (thunder attack)
Tenjo Tenge : Hakka Sou Dou Shyou (Takanagi attack)
Tales of Phantasia : even the SuperNES made the voices credible !
not only fighting series
even the transformation of Sailor Moon or Cutie Honey as a name.
Well, I've got a question since some magazine said, long time ago, that a game made this way to shout before/while
an action.
It was said that Street Fighter created this style with its Hadoken and stuff.
But some one told me it was Grendizer.
Do you have any clue ?
