List of Gurren Lagann Characters - Boota

Voiced by: Shizuka Itou (Japanese), Julie Ann Taylor (English)

The unofficial mascot of Team Dai-Gurren, Boota (ブータ, Būta?) is a small pig-mole from Giha village, whom Simon keeps as a pet. Boota is characterized by his sunglasses and star pattern surrounding his tail. No matter how many years pass, Boota's physical appearance does not change much. Although he can only say "BOOTTA!" (hence the name), he can understand humans, and even has near-human intelligence. His favorite spots to stay are between Yoko's breasts or on Simon's shoulder. He has ripped off his tail and consequently the tip of his rear end as an emergency food supply for Kamina and Simon so as to provide energy to the starving duo during a crucial fight, and also has served as a morale figure to Yoko, when she first hesitated at piloting Gurren in place of Kamina. Interestingly enough, he too was thrown in prison along with Simon, and even had his own pair of miniature handcuffs. When Simon and Viral broke out of jail, Boota loyally ran to Simon's shoulder. However, upon seeing Yoko again, he hastily jumped in her cleavage once more.

Boota proved his true value to Team Dai-Gurren in episode 25, when he asked Viral for entry into Gurren's cockpit and from there, released a massive surge of Spiral Energy to aid a worn-out Simon in his task to power up Super Galaxy Dai-Gurren. Lordgenome stated that this occurred not only because humans aren't the only beings capable of generating Spiral Energy, but it also may be a reaction from Boota, being frequently exposed to Simon's Spiral Energy. In episode 26, Boota stands to protect Lordgenome from the Anti-Spiral trying to attack him, and when their Spiral Energy resonates, he is transformed into an anthropomorphic humanoid. His attacks are laced with Spiral Energy. Curiously, his "human form" appears in the prologue of the first episode. The glasses Boota has in his humanoid form look similar to the glasses Nono wears in her Buster Machine No. 7 form in the anime Diebuster. Unfortunately, this transformation allows the Anti-Spiral to trap Boota in the Multiverse Labyrinth; when he was freed by Simon, the transformation was undone.

In the epilogue, he is seen wandering the world alongside an aged Simon.
