Former WWE Superstar Yoshi Tatsu is now going under the name of Yoshitatsu. WWE owns the trademarks to the name Yoshi Tatsu however, he believes he can use Yoshitatsu as it is his fathers real first name.
His new gimmick is that he’s the Bullet Club hunter claiming WWE and NXT wrestlers and staff wear Bullet Club T-Shirts, even in WWE headquarters and he is sick of those people wearing them.
It's a storyline of course.
