Kang as the next Thanos?

Don't think Galactus has it to be a Thanos.  He's a countdown monster villain.  He's something like a Doomsday.  If they try to make him multiple phases long, it would end up the same as the previous phases. Silver Surfer shows up and starts the clock on Galactus coming (Loki in Avengers). They build up the forces while maybe collecting artifacts. Surfer changes sides (Nebula). Galactus has other Heralds that fight the heroes when Galactus gets there.

I think Kang is more like a Magneto or Loki.  That villain that keeps showing up throughout the movies.
