Who is Krall from Star Trek:Beyond?

Hey there today i wanna clear this question...WHO IS KRALL?Well here's the answer:

(EXTRACTED FROM VILLAINS WIKI)

Krall was originally known as Balthazar M. Edison in the 22nd century. Early in life he joined United Earth's Military Assault Command Organization (MACO), rising to the rank of Major. He fought both against the Xindi and then the Romulans in the Earth-Romulan War. After the founding of the Federation the MACO forces were absorbed into Starfleet. Edison was given the Starfleet rank of Captain and in 2163 was named the commanding officer of the USS Franklin, the first Earth ship to have reached warp four.

A year later, the Franklin disappeared. Popular speculation ranged from the ship being captured by the Romulans to the ship being caught by a giant green hand. Having crashed on the M-class planet Altamid, Edison and the other Franklin survivors felt abandoned by the Federation. Sinking into madness, the survivors came to despise the Federation for its ideals of peaceful cooperation. Transformed, Edison began calling himself Krall during this time. Finding a cache of weapons, ships, and technology on Altamid, Krall and his forces began plotting their revenge against the Federation in retaliation of them never come to help them and their embrace of diplomacy and tolerance that he never agreed in the first place. Their equipment included humanoid drones and swarm ships, as well as technology that prolonged life by absorbing the life from other beings, transferring energy from the victim to the user, resulting in said user being physically morphed and mutated into having at least some of their victim's physical characteristics. It was this technology that mutated Edison into Krall, at the cost of his already damaged mental health, causing him to lose some of his human personality, have somewhat slurred speech and usually speaking in an alien language.
