I think aliases wildly depend on the character itself. An alias is many things, but most importantly, it's a first impression of the character, like an elevator pitch. It should capture the essence of the character and also distinguish them in a crowd.

In general, appearance/vibe + profession is my go-to. "Lupine nerd", "Wild Clown", "Reckless Scumbag".

However, for some characters, it's fine to go with something particularly evocative or poetic. Like "Shattered Dreams" or "The Hierophant" or whatever, as long as it's powerful and accurate. Like, if you're called "slave", that better be literal.

There's nothing worse than seeing a char called "The Eternal Wheel" and it's just a fairly normal person. An alias should be extremely descriptive and powerful.

I think putting the personality in the alias is fine as long as it's extremely accurate and core to char as well. It's fine to also change it as long as you keep one word consistent
