|Season:||Bakuryuu Sentai Abaranger|
Burstosaur Bakyceloknuckles (爆竜バキケロナグルス Bakuryū Bakikeronagurusu?): A Pachycephalosaurus nicknamed "Baki" (バキ Baki?), he was the first of the Burstosaur eggs found. Once hatched, he remained at DinoHouse until he grew large enough to be placed in Brachio with the others. His personality is quite kiddish, similar to Kera. He forms MaxRyūOh's right arm. In the finale, Baki said to Mai that he's happy that she's so close with her dad (Ryouga), and to be good to him. The explanation of Bakycelonagurus's name is very complex. Baki-baki is said to be the sound of many swift jabbing punches in Japanese manga. Naguru is a Japanese word for a punch, as thrown in a boxing match. These two words are spliced into the term Pachycelphalosaurus thus: Baki-ycephalo-naguru-us. Because the "saurus" splice onto the end of the word naguru sounds somewhat similar to the English word "knuckles", many mistakenly believe the Bakuryū's name to be BakyceloKnuckles. However, the Japanese phonetics for knuckles are nakkurusu (ナックルス), not nagurusu (ナグルス). He ends his sentences with the word "Baki".
