to the guy who put the Arbiter as his dad, that'd be fucking ace
Father: Jecht (FFX)
Mother: Sarah Connor (Terminator series)
Best mate: Zell (FFVIII)
Archenemy: Carnage (Marvel Comics, leading up to the events in the "Spider Wars" season finale from the 90s cartoon show)
Rival: Jecht (FFX - and yes the same Jecht that is my father, not a separate one for the position of Rival)
If we imagine that (and this isn't hard given the prevalence of FF characters in my family, I've been playing a lot of FF again recently, sue me

) I'd have a Final Fantasy-esque party to go on world-saving adventures, I would be the hero and I'd have a sword like Tidus' (make that two, I'll dual-wield), except I'd be badass and not a whining *****, I'd adventure with Zell, my mother (the fact my mother is with me doesn't diminish my badassery by the fact that she's my mother, though it MAY diminish my badassery because she's
Sarah fucking Connor), and:
The Doctor, with the TARDIS' time travel functions disabled, so it can only move in space - this would be our airship and give reason to why he's locked here. Tbh he'd be a pretty good Father too.
Freya (FFIX)
Yahtzee (I don't care that he's not fictional. He can throw his hat, Oddjob style)
Paul Phoenix (Tekken series - he can actually be Zell's dad too, it'd make remarkable sense, think about it)
Deadpool (Marvel Comics)
Terra (FFVI, also my love interest ;])
We'd also be able to cast "Optimus Prime" as a summon magic.
Yeah, I picked up your idea and I totally ran with it. It'd be awesome though - the kind of universe that sees all these characters together just requires condensed awesome. We've got magic, big swords, superpowers, giant mecha, death robots from the future, a flying police box that's bigger on the inside, rat people from a country where it's constantly raining, and all manner of other cool shit.
Am I feeling lame enough to fanfic this? No. But if you asked me that question eight years ago, when I was twelve, the answer would have been "HELL YES."
Edit: I knew I was taking too long to type this and someone else would put Deadpool in, but hey I envision him more as an ally to my sensibilities than a father
Edit edit: Just read this through again. It is clear to me I've been playing WAY too much Final Fantasy recently. Forgive me
