Ixna

From Tardis Wiki, the free Doctor Who reference

Ice Lord Ixna was an Ice Warrior who had travelled to Earth in search of conquest, in the name of Ice Queen Iraxxa. He landed on the South Pole near Snowcap Base and was frozen in the snow.

Several centuries later he was unfrozen due to the climate changing to become warmer.

He later attempted takeover of the Snowcap Base, leading a group of Ice Warriors, by freezing down planet Earth, but was defeated by Tegan Jovanka and Ace who reversed the polarity by turning back on the heat. (GAME: Reverse the Polarity [+]Loading...["Reverse the Polarity (episode)"])
