Might as well since it is not too bad of an idea.
Fighting pose:
Nothing noticeable, I'm just a lifeform floating in the 97th dimension.
Ability:
God Mode - Perfect control over anything non-living for a pretty limited time.
Attacks:
Subspace Flow (the entire existence squeezes you into a bonecrushing form, fairly easy to avoid, but huge damage - similar to Sheer Cold, but more accurate and not necessarily 1-hit-KO)
Sleep Kick (A nauseatingly loud kickdrum blasts you into unconscious state, rather tough to avoid, minimal damage - similar to Secret Power in Tall grass in Gen IV)
Goaforce (Veils itself inside a field of energy - similar to Barrier)
Masochistic Sleepwalker (Takes control over the unconscious opponent: impossible to avoid while asleep, can not use if the opponent is conscious)
Psycibel Boombox (Blasts full volume glitchy sounds from everywhere, rather tough to avoid, medium damage - similar to Hyper Voice)
