if billy uses telepathy against Apocalypse he will get a violent feedback also and can billy control his molecules on the subatomic level there is no real way for billy to win this every single power he has Apocalypse has a counter for
telepathy Apocalypse is immune
transmutation Apocalypse molecule manipulation counters that
lightning thor's lightning only managed to stagger him i doubt billy's will do anymore than that if it hits him Apocalypse also has force fields and teleportation
brute force Apocalypse has taken on the hulk and held his own against 2 thor's at once not to mention try punching something that can change from it's physical state at will billy punches him he can change to a liquid state
forget wizdom Apocalypse is way smarter than billy not to mention if this place runs off tec Apocalypse could turn the whole battle field against him
they both have the power of gods but one has the brain of a 12 year old while the other could figure out how to use tecnology hundreds of thousands of years more advanced than he should
