Because Killua is behind the ant standing his ground/blocking. The fact that Killua is anchored in place indicates he was right on the ant when the blast happened, as the last time we see him on panel he is far up diagonally from the ant. So either his actual position was right behind the ant near the ground and he tanked it while anchored, or Killua seamlessly guided through the explosion despite moving towards the blast in mid air, and was able to anchor himself when he touched down.
It is pretty well evidenced that the former is what occurred.
non sequitur.
Dude, he was firing flees. Do you think non nen enhanced fleas could be propelled at such speeds and actually make it to their target hundreds of meters away, let alone actually penetrate Killua in the manner it did?
Also I presume that Killua utilized some form of ten/Ken to tank the blast. Not that he is casually that level in standalone durability.
Via empowerment. Aka it is still coming from the person. And just because a fodder can potentially multiply their power, doesn't mean it is going to make them able to actually fight high tiers.
And so killua being able to murder several ants attacking him at once, murder Rammot, and also beat out several other ants (Ikalgo, the gemini twins). Not to mention that Killua kept pace with and took
attacks from
Hair Modo Palm who used it as armor to amp her
durability while focusing her
nen solely on offense.
Electricity still needs to be potent enough to affect someone of a certain strength. That's why people, particularly large men, can be more resistance to tasers compared to other. Killua's stun had to be strong enough to both stun him for multiple seconds, and also make him feel pain. Said feeling invigorating youpi.
No. It does not fall straight down on the ant. If it were materialized in air, it would fall on top of the ant from a completely vertical axis. We are explicitly shown
Jupiter moving diagonally meaning it must have been accelerated after being materialized. Also evident by it hitting him from that angle as he was running away.
He says he calculated which direction NGL was. Punched the ant into the upper spheres of Earth, and then proceeded to tell the ant to go back to NGL. It's pretty obvious what occurred with the feat.
And you'd be incorrect in your imagining given the scale of that tree. IRL trees much thinner in diameter, and smaller height wise, have survived literal tornados/hurricanes crossing them thanks to root strength. Shaking a tree of that size not only requires knocking back it's mass but also going against the force of it's root resistance. Which for a tree of that size would be quite ridiculous.
