However, when the Planet Express crew ran into the former cast of Star Trek on Omega 3, Melllvar finally appeared to explain how he had kept the Star Trek cast alive, though in obsession with being the biggest Star Trek fan, he would often focus his anger on Welshie, which eventually killed him, much to Fry's dismay.
- Both his name, and what he says seems to imply that he is Welsh.
- According to the commentaries, he apparently says "I am very drunk" in Welsh.
- That Guy with the Glasses contributor Welshy has said he is named after him.

Takei: Ever since then, Welshie has been a welcome participant in our escapades.
Welshie: Aye, Dwi iawn 'n feddw!
