The turtle's humungous weight is enough of an advantage most days, and it has a powerful gravity magic which can immobolise its foes, leaving them helpless and unable to escape being trampled under it. The beast is painfully slow, but the fact it neither eats nor rests makes up for this almost completely. When pushed into a corner it is capable of firing intense lightning (electric-type magic) beam attacks from its mouth or the eyeball on its heart, this attack has only been truly blocked by the Hero of the Shield while using the enhanced Wrath Shield 3, but can be mostly blocked with his enhanced Soul-Eater Shield as well. What's truly terrifying about this attack is that it not only wipes out mountains, but it drains all of the victims SP, leaving them truly helpless before the next shot, which can come as soon as immediately after if it had managed to absorb enough SP in the last one.
To compensate for its slow body and limited movement, the turtle is also able to summon Demon Bat familiars as well as many others including those that resemble Gorillas, Yetis, floating eyeballs, caterpillar-like familiars and even zombies made from the people who lived on the city on its back. This extends to the beasts inside as well. There are several more familiars that protect the heart that act like an immune system. There are Mimic Type Familiars for path concealment as well, making it hard to even find the heart. Deep within the turtle is the heart which is capable of using the same strong gravity magic and high powered beam as the head but the latter is slightly less powerful to avoid damaging itself.
The turtle was rendered near immortal due to the blue hourglass within its body, the only means with which to kill it ultimately is for someone to take out both the heart and the head within moments of each other, likely before either can fully heal. Blasting its head clean off has even been shown to produce a replacement head just moments after.
