Although not even the assassin's help was enough, thus Chrell decided to go supernova. Unfortunately for Chrell, the RunawayXavin was able to contain his supernova and thus he only succeeded in killing himself.
Skrull Shape-Shifting: Like other Skrulls, is a shape-shifter. They can mentally cause the unstable molecules that comprise his or her body to become pliant, enabling him or her to assume other forms through muscular expansion and contraction. Once a new shape has been assumed, it takes a conscious act of will to assume another form or revert to natural. Hence, Skrulls do not spontaneously lose their assumed form when asleep or unconscious. Skrulls in altered form will, however, revert to their original forms at the moment of death.
Skrull infilttration Ritual: The Skrull took part in a ritual a mixture of science and magic that imbued them with the powers and memories of the selected subject. This allows the subject to go undetected in human form by Iron Man's technological scans, Charles Xavier's mental scans, Spider-Man's Spider-Sense, Wolverine's animal senses, or any other conceivable forms of detection. So subtle and powerful is this form of concealment neither Doctor Strange can detect the Skrull with the Spell of Tartashi, nor could the Elder God-powered Scarlet Witch using Xavier's psychic powers delve past the memory blocks.

Right-Eye: Chrell appears to be unable to open his right eye all the way (if not at all). It is possible he may be blind in this eye or that his eyesight is restricted.
Skrull Shape-Shifting: Skrulls only take on the appearance of an object or person and none of that object or person’s characteristics. There is a limit to the size of the object or person a Skrull can imitate. The average Skrull cannot distend his or her mass any more than 1.5 times as large a volume as his or her original volume, nor can he or she contract his or her mass any more than 0.75 a volume as his or her original.
