Gravimon

Gravimon is an Unidentified Digimon whose name and design are derived from "gravity". It is the general of the Earth-god Army of the "Big Death-Stars". It is a tactician that has the ability to freely manipulate gravity, and with that ability it has the ingenuity to survey the entire situation and control the course of the battle at will. The beauty of its plots are even said to be "ingenuity, as if gushing forth", so it makes sport of the enemy army by weaving formulaic tactics together with creative schemes. God Beast Digimon account for the majority of its army, which has overwhelming strength in terms of military power. Because it enjoys stimulating tactics, it uses the battlefield as its testing ground. It is an investigative Digimon which continues to zealously research questions like, how many casualties can be produced easily, which tactic lets it listen to a multitude of screams, what creative scheme will surprise the enemy or ally as they die, which method will cause all of the opponents to die without shedding blood, and so on.

Digimon Xros Wars
Attacks
 * Octa Gravity: Uses its eight tentacles to manipulate the gravity on the battlefield, controlling the opponent's gravity based on the flow of the battle and making them lighter or heavier.
 * High Gravity Pressure: Elastically extends both of its arms and burdens the opponent with intense gravity pressure, compressing them to their limit.
 * Gravity Ban: Places the Digital World's gravity pressure upon itself until it reaches its limit, then detonates the entirety of its energy all at once in a phantasmal bold move. This forbidden self-destruction technique has enough destructive power to partially destroy a star, but might obliterate Gravimon itself. Although it can regenerate if it waits for many long years, even Gravimon doesn't know how long it will suffer for until it regenerates.
