Terara is the Earth Dragon who awakens once every 5000 years to recreate the world. He was eventually held back by the Keroro Platoon, who were then turned to dragons by Shion and made to be his servants.
At the end of Keroro Gunso the Super Movie 4, when the Earth Dragon was summoned and had threatened to destroy the Earth, Shion appears to sacrifice herself, but she and the Platoon members are all okay and back to their original selves. Then everyone noticed that Shion was holding a glowing blue egg, it soon began to hatch and out of it's shell came Terara, a small Keronian version of the Earth Dragon.
Shion later takes Terara in as her partner, and the two became good friends. After bidding farewell to Momoka Nishizawa and her friends, Shion returns and attends her school, along with Terara. Terara and Shion have also been visited many times by their new friends, knowing that they are not alone.
Terara acts childish and in some ways rude, like when he jumps on Kururu's head, patting him rashly, and calling him "a good guy", but his childishness isn't too bad, for he go back to Shion claiming "But, Shion is special" and he continues to say that he loves Shion, with a hug.
Terara is a navy blue keronian with lighter aqua tadpole markings that go up into a point in the middle, he does not possess a tadpole tale, but a dragon's tail. Like a Kiruru, his hat flaps are not from his hat but are part of his skin, he has a 'cat' mouth with two fangs on each side, gold cat like eyes, and Shion's hat. His symbol is an egg shattered to pieces.
Shion is Terara's "special" friend. Shion was the only one to ever hear Terara's voice as the Earth Dragon, and when she helped free him, she realized her errors and decided that she needed to save both Terara and the world. She managed to soothe Terara down, with the cost of passing out and when the Keroro Platoon tried to save her, Terara stops them to be the one to save her. Later on when Shion came back after the Earth's reset, she is seen holding an egg containing the reborn Earth Dragon named Terara. From that moment Shion and Terara are never seen far away from each other, doing stuff such as going to school, playing tennis and going out shopping.
Terara has a strained relationship with Kururu. In the movie, Kururu has a great hatred for Terara after he patted his head rashly, and he falls to the ground embarrassed. He is later seen chasing Terara out of the credits.
Terara seems to like Momoka, though not as much as they love Shion. During the credits when Shion was running towards Momoka, Terara is shown holding his arms out to Momoka, in a hug motion.
- Terara's name comes from the Latin word Tera meaning Earth, referring to the fact that Terara is an Earth Dragon.
- Terara's voice actor also voices Pikachu from Pokemon series.
- Terara is often referred to as female and a rumor was started where it was 'assumed' Terara was female due to Dororo hold a blue flower out to someone off screen (that was either Shion, or Terara, or both) at the end of the credits.
- However, in Terara's card earned from Keroro Gunso the Super Movie: Gekishin Dragon Warriors de arimasu! (game), Terara is referred to as "コイツ (koitsu)" a term that can translate to "this guy/dude", this proves that Terara is a male.
