Glitch:-

Absolute Access(Phasing):- Phasing Through any solid matters, like walk through walls.

Intangibility:- Obito's kamui, how attacks used to go through him as if his body isn't real.

Lagging:- How like in games when our game lags our characters keep on going backwards, for example in pubg, when the game lags our character keep on going back to the previous position whenever we start moving forward.

Teleportation:- Using reverse engineering method of lagging, where in lagging one keeps on going backwards, in teleportation, we keep going forward as far as we can see.

Malleable Anatomy:- Via glitching his body like a code, he can rewriting his body like a code to change his appearance, like shapeshifting.

Enhanced Physics:- He is at peak human level, in strength, endurance, speed etc.

Cyberpresence:- Like Ultron from Avengers, he can put his consciousness in laptop, and also take over th internet as well, he can also have a physical body made up of digital codes, he can also have his real body hidden in internet

Error Inducement:- Let's say Overhaul threw the quirk erasing bullets towards me, with error inducement, the bullets will always miss, something will come up through which the attacks would never connect and will always miss.

Logic Defiance:- Via glitch quirk he can defy common sense and logic, anything you think is logical will become false and anything you think illogical will become a reality. For ex:- it's logical for a human to need oxygen to Live, but with logic defiance, he might not need oxygen to survive at all, or he can run at the speed faster then light yet he would remain unharmed.

Reality Hacking:- He can bend the reality as per his will, it could be like the real world is a game for him, he would see aim crosshead in real life, he can change the world by adding codes, like then cheat codes in GTA.

Glitch Physiology:- via glitch physiology, he became a living glitch a paradox not meant to exist in the real world, like a god who is walking among men, when he shouldn't be doing it.

Self Ressuruction:- via glitch he has unlimited lives, like in Mario we have 3 lives but Izuku here as unlimited lives and he has made himself a part of the universe, an integral part of the universe, so as long as the universe exist, he will exist as well

Digital World:- He can see the world in 1s and 0s

Biology Hacking:- He can use glitch to let's say change one's physiology, like changing someone's bodily functions other then himself, like making someone else not need oxygen to Live or become self sustaining.

Back Tracking:- Will update it soon
