Bakin is the primary antagonist in Metal Fight Beyblade VS the Sun: Sol Blaze, the Scorching-hot Invader. He is the grandfather of Helios. His Beyblade is Dark Poseidon 145WD.
Bakin raised Helios since he was young and taught him almost everything he knows, from how to walk and talk, to how to launch and battle with a Beyblade. In an attempt to achieve his ultimate ambition, to rule the world, he takes his grandson to what seems like Atlantis and uses his bey to unlock the ultimate Beyblade, Sol Blaze V145AS, for his grandson. Little did Helios know, however, that his grandfather was up to a nefarious plot.
Metal Fight Beyblade VS the Sun: Sol Blaze
Throughout the movie, Bakin has been ordering Helios to go after Japan's top Bladers. Helios went as far as to challenge the strongest Blader, Gingka Hagane, and even succeeds in defeating him easily. Noticing that Masamune Kadoya, Ryutaro Fukami, Tetsuya Watarigani, and Tobio Ookie with the latter hiding from the group, he calls on Helios to attack the four. Helios does this with little resolve or pity and did not even use a hint of his full strength.
Angered by this, Gingka and the gang come to challenge Bakin and Helios to a rematch on their high-grade water palace. Helios starts off by eliminating Kenta, Yu, Benkei, and Masamune with his Blaze Execution, and nearly incinerates their Beyblades. Gingka uses his Pegasus Starbooster Attack to blow away the flames and free his team. Gingka then tells Helios to battle him and decide who is truly the strongest.
The two start their battle with a huge barrage of explosive attacks. Blaze begins to burst into flames again but Gingka counters with his Storm Bringer attack. Helios is becoming worried as he knows that Gingka is getting the best of him. Helios calls out Blaze Execution and Gingka uses Galaxy Nova and an awesome purple energy burst sends shock waves that spread across the globe, with severe weather following. However, Helios is defeated by the clash and Bakin is dumbfounded and furious. Bakin leaves Helios and attempts to fly into space to avoid an impending asteroid that could very well destroy most of humanity, with the rest under the elder's foot.
Helios and Gingka attempt to stop him but are attacked by his Dark Poseidon.
Afterwards, a mysterious blader sweeps in and pushes Dark Poseidon back, it is Kyoya Tategami. Kyoya lets Gingka and Helios escape. Bakin seems to have the upper hand on Kyoya, then Kyoya lets out his special move, King Lion Furious Blast Shot, which ultimately defeated Dark Poseidon and Bakin, this was the last time Bakin was seen.
