Kobeh is an extraterrestrial encountered by Gen 13. Although scant information exists about Kobeh within the pages of Gen 13, the following link has detailed information about Yoda him.
Death
Kobeh’s body dematerializes upon his death. Fairchild speculates that this may be how members of his species die. (An equally plausible theory is that this method of death is an effect of Kobeh’s membership in a spiritual order and that Kobeh is being reunited with a force of some kind.)
Grunge is visibly distraught at Kobeh’s death. Roxy comforts him by telling him that Kobeh is in their hearts; and that as long as they’re around, Kobeh will always live on in their memories. It remains unclear how true this is as Kobeh is never mentioned or thought about again by any member of Gen 13.
Speech
Kobeh has taught himself English, although he speaks with a non-standard sentence structure of the form:
<direct/indirect object> <subject> <verb>
For example:
“Merchandise we are.”
While under moments of pressure, however, Kobeh tends to revert to the more-standard, subject-first syntax.
“Guards say a monster is loose aboard the ship!” {Emphasis by Kobeh.}
When speaking complex sentences, he mixes both sentence constructions, rendering his meaning difficult to ascertain.
“That spot in the roof, you must break through. Then you must re-enter through the airlock, once you have left this pen.” {Emphasis again by Kobeh.}
