Wise & strategic, this turtle-like Bakugan is a thinker & philosopher-warrior. He is an excellent strategist & acts as Wynton’s secret weapon in terms of planning battles & executing attacks. Not much of a fighter himself, Turtonium prefers to act as support, healing others, & helping his friends succeed.
The second tortoise-like Bakugan after Juggernoid.
Turtonium's working name was "Archeleon", a reference to the extinct Cretaceous-era turtle. Two images with Ventus and Diamond Turtonium, along with its working name, were added to and subsequently removed from the Bakugan Instagram story.
