Sometime inbetween he left Megatron for his own agenda, he was killed by Q and the Star Trek Next Generation.

When this failed, Discord tried to kill Khan but Khan escaped though badly hurt by Discord and Stane.

Legends of Light and Darkness
Khan joined Malefor as his own right hand man to expel revenge on Discord and on The Star Trek Next Generation Universe. Khan alongside his allies makes the challenge to the universe to see if anyone is man enough to go against them. When apparently no one knows where Equestria is, Khan  has an idea how to lure someone out and asks K.Rool to do it. He takes on the task of getting the info out of Harvey Kinkle with the help of Carnage and Horvath. He leads the attack on Equestria with his allies and when it's done with he confronts Bender, Skipper, Slade and Bowser on this. He reports this back to Malefor when he returns and when the others tell him he recalls his encounter with Slade and Bender. Khan gives news to Malefor about Okionney's death while deciding on working something against the heroes. Khan is seen with Malefor advising him that he can't just force The B Team to say or do something considering that Axl isn't talking or anything. Khan decides on blowing Interpol which he does with the Pack placing bombs all over the station. Khan afterwards has Malefor call on Darkseid to the next part of the plan.
