Sanda

Sanda (サンダ) also known as the "Brown Gargantua" was one of the two kaiju's spawned from Frankenstein. He was the kinder one of the two Gargantuas, this was do to him being raised by humans.

History
Sanda, the Brown Gargantua, emerged shortly after Frankenstein’s battle with Baragon as a young, child-size kaiju and was captured and studied by a group of scientists (he supposedly grew from pieces of Frankenstein’s flesh). However, the young Gargantua eventually grew tired of his captive surroundings and escaped back into the mountainous area of Japan. Then, a year or so later, Sanda, who had now grown to 30 meters in height, reappeared when the JSDF attempted to kill his “brother,” Gaira, the Green Gargantua with Maser Cannons, saving Gaira and taking him into the mountains. However, when the still human-liking Sanda discovered that Gaira had been eating humans as his main diet, the Brown Gargantua attacked Gaira, forcing him to retreat to Tokyo. Sanda followed the Green Gargantua to the great city where the two engaged in a fierce battle in the city streets. The battle eventually moved out to the sea, where a volcano engulfed both Gargantuas.

Sandra then later appeared in the Go! Greenman episode, Greenman vs. Sanda.
