H4X is half H4X Human, half human. He is dons green hair, dark green shirt and blue jeans. His weapons are inside of his pocket from his blue jeans. They can even enlarge for smashing objects like rocks and his enemies. He can even break the fourth wall and grab some meme pictures and throw them at the opponents. Even he can grab comments from social media from breaking the fourth wall.
H4X shows no sympathy to anyone who is hurt, unless he is doing an adventure with them. He always takes things seriously for everything, so don't bother joking around with him. H4X is actually friendly to nearly everyone in his main series, in Robo-Apocalypse, his personality changes gradually.
H4X is the main hero of the game, where he ventures through the Webtopia areas to find what he really is, when he thinks that he is actually 100% human. He has 6 days to find out before the whole Webtopia shuts down because of a deadly virus.
H4X is an unlockable character in R-A3:FoC. He was actually the one who saved Earth from Robo-Rampage and Dr. Mech-Brain. H4X usually attacks with his PC Keyboard and can do graceful and brutal attacks like grabbing opponent and hitting their chest by holding them with a binary code circle and kicking their chest rapidly. H4X's Super Strike move shows him uppercutting the opponent and throwing hate comments (mostly death threatening comments from YouTube and DeviantArt) at them. He finishes it off by blasting them with binary code energy blasts.
- "H4X" actually means "HAX" which is another way of saying "HACKS", even though H4X IS a hacker.
