Colonel Blast is a minor character from the 1986 animated series She-Ra: Princess of Power.
She-Ra: Princess of Power
Blast is a very similar character to Rio Blast who appears on the She-Ra: Princess of Power series. Colonel Blast is a member of the Evil Horde who features in the 1985 episode "The Wizard" commanding the ranks of Horde Troopers at a Horde outpost in Moorstone. Although he is not a cowboy like Rio Blast, this character had guns built into his body in the same manner as Rio, as well as sharing the same last name. Given that the characters from the 1986 wave of toys were in their development stage at this time, it is quite likely that Colonel Blast is an early version of Rio, promoted on the show as a possible upcoming figure.
