You are making statements, not explanations. 

I recognize now Garrett is horrendously OP, as the God types like Raptormam's char are inactive and he was made to counter those. However, he needs to return to Earth to advance the story and allow me to introduce my next character. Do you see a better way to get back to Earth than following those people who know how to use portals? Because I don't. 

Here is what I mean by "immersion breaking". Why in the hell, would anyone who has this immensely powerful ship, ever go down ever to brawl with some punk on the ground? Better to not have them at all. 

You're perfectly illustrating my belief in your irrational vehicle hate. Suppose Beowulf of Titan had treads instead of legs, and a driver. Is it now not a character? Would you have denied it if it had treads and a driver? Can you show me a quote by Skallagrim saying vehicles don't belong with characters?

Garrett's "ship", which is really my terminological laziness, is much smaller than a 747. It is half the size, in fact. It is a plane which can go into space. If/when a God shows up, I will bring him from retirement.
