Lol That's funny. But I assume in water, it can move normally, right?Answers in the quote. Okay, if you don't have any answers, let's start with Mamaragan.
Okay so, it has the generic number of tentacles, so 4. You're about right in the height, each tentacle around 1 meter, 1,5 meters. The polyp moves through tumble, basically, it moves it's mouth/head downwards, touching the ground, and then releases the suction off his foot, basically doing a flip. It's a weird way to move, but it is real lol. So yeah, he can tumble around. He does not require water, the lightning keeps him structurally sound for the short remainder of his stay in battle.
Also, Mamaragan has lightning affinity, same as the tiny medusas, but can't use Lightning techniques. In Polyp form, he can use Box Arts.
Ok my question is, can I summon them after my opponent has released a lightening attack? I mean will it be able to defend me successfully??
