You got Pegasus Seiya from Saint Seiya, Ryo Sanada the Wildfire from Yoroiden Samurai Troopers aka Legendary Armor Samurai Troopers aka Ronin Warriors, Shurato Hidaka aka Shura-Oh Shurato from Tenkū Senki Shurato aka Legend Of Heavenly Sphere Shurato. The thing that they have in common is that they get Upgrade Power ups. I gotta keep up with Tenkū Senki Shurato to see it though.
