I came up with a name for him and it's pretty stupid as always, now I'll tell you a little about the character and his name


This bro is obsessed with all things physics and chemistry, and loves all sorts of nonsense related to nuclear physics. His name is Tvel, it is not his real name, but was chosen by him instead of his real name and yes, it means something:

•A TVEL is the main structural element of the core of a heterogeneous nuclear reactor, which contains nuclear fuel. It is a metal tube inside of which there are fuel pellets made of uranium (or sometimes plutonium, thorium, etc.).
This tube is sealed hermetically at both ends to prevent radioactive fission products from escaping.

I won't tell you his real name yet, it's like a great secret of the character, but it turns out his name is Tvel.
