Is it fair for me to come into this topic?
Anyways, it's quite possible for anyone in DBZ to defeat Base Accelerator if they knew about pulling your punches at the right moment. Unfortunately these people are not Kihara Amata so fuck that shit.
We're in two pages so I'll be shocked if this isn't explained but its like this my friends. If it has a vector, #1 strongest as fuck Esper can reflect it. If Goku fused with every goddamn thing on the Earth, doubled Potara and fired off a universe sized fucking Genki-Dama.
Accelerator would reflect it, I literally shit you not. As long as its a vector, he can't mess with it and it will never hit him. As far as direct attacks go, there's few and far things between that can break through his defenses.
1.) Knowing to pull your punches right before they hit. It was used Kihara Amata and the only reason he knows this is because he taught the little upstart everything he knows. And then shit went south once Black Wings came into the picture.
2.) Having something whose vectors don't exist naturally. For example straight up specific kinds of magic which don't have vectors don't really allow Accelerator's reflection to handle. The same thing happened when he fought the #2, Kakine Teitoku and his Dark Matter. He was unable to handle the dark matter which doesn't technically exist.
Until the fucker did! The fucking bastard literally took Dark Matter, proceeded to shove it up Kakine's ass and then when Dumbass Mc. Butthurt decided to go after Yomikawa, Black Wings came out and Kakine got fucked up so badly they had to put what was left of his three brain lobes and organs into a fridge.
...And then more shit, zombies, giant beetles but that's another story.
The point is, even something like Dark Matter which doesn't even exist in the world and could at first get passed Accelerator's reflection was quickly taken control of by the guy.
Other than perhaps someone like Majin Boo or anyone with magic, very few people in the DBZverse can really hope to defeat Accelerator directly. There's may be tons of ways they can do it indirectly, but they're going to be hard pressed to get through that defense of his.
