Ok so the thread in another forum isn't getting the publicity it deserves so I figured I would post a theory here.
Ok so the Lavos' spawns always travel through space and has to repeat a process to create new spawns. Now different types of planet DNA can mean different looking Lavos. It may also mean a different means of travel.
We know Jenova crashed into the planet in FF7 with a comet. Ok so it doesn't mean it's impossible that a lavos' spawn rides a comet instead of acting as one.
Anyway, after weakening the planet and growing strong enough, Lavos emerges destroys the planet and creates spawns.
Jenova had a problem. It was sealed in a geological stratum... So it could only influence life.
Lucca says the words that the human race is raised like farm animals only to be slaughtered. So does that mean Lavos' influences things? Yes we can see his influence on Queen Zeal and the Mammon machine and all of that stuff.
We can also see Jenova's influence by influencing Shinra to make reactors and soldiers and the injection of Jenova cells with the showering of mako.
They each have similar characteristics and each came in a similar way.
Does this mean we have a relation between FF7 and CT.... Not only are my two faves of all time, but I honestly think we could have a connection here.
So I will leave it up to you, what do you think?
