These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Lost Universe
Fanon - Mostly the 'Lost Universe is in the same Universe as Slayers'; this would, among other things, mean that Canal and Darkstar would have the trope God Was My Co Pilot. This is under fan debate, of course...
Fridge Brilliance - And a touch of Fridge Horror in Canal's obsession with equipping herself with ordinary weapons. None of the normal stuff she picks up can hold a candle to her Lost Ship tech so it's kind of odd that she goes on and on trying to beg borrow or steal mundane cannons and missiles for herself, until we discover that Her Lost Ship weapons consume her pilot's body and soul for fuel, and her last pilot died from overusing them.
Fridge Logic - They talk about years, days, hours, etc... That sure makes sense on planet Earth yet, when we go to space, we cannot work with those units as those depends on the relation between the Sun and planet Earth.
There's no reason they can't have a standard day as a universal time reference for space travellers. Otherwise nobody could schedule anything.
Also when they go to a planet it always seems bright as day. Then comes to wonder... "Where's the star that lights all that?!?!"
Jerkass Has a Point - Canal wanting to get rid of Millie is kind of understandable because she adds a lot of expenses to their already-strained budget. The fact Millie absolutely refuses to ever use the food synthesiser, despite knowing that she cannot hand-make anything without blowing up the kitchen, is an added deal breaker; let's face it, as Canal points out, having to repair the kitchen three times a day, seven days a week, is expensive. Plus, Canal is a Spaceship Girl — how would you like somebody detonating bombs inside of your body?
Tear Jerker - After Canal takes out Gorn Nova in the anime, the data banks of the Swordbreaker are slowly consumed by fire. Embrace plays in the background as we see shots of her and Kane as children, slowly fading away as her memory is destroyed. As she herself vanishes, she says, "They weren't all bad memories, were they, Kane?"
