First Steps" just introduced the most powerful being in the MCU and was pretty nonchalant about it. Franklin Richards - the newborn son of Reed and Sue Richards – made his debut in the latest MCU film and drew the immediate attention of big bad Galactus.

Galactus ends up giving the Fantastic Four an ultimatum, telling a pregnant Sue that he'll spare Earth if she gives up her powerful unborn child to him. The group declines his deal, which further angers Galactus, sending him on a vengeful mission to both destroy Earth and take Sue’s child.
