This good.
And crush any obstacles for Killua from fighting Black Star as Akame would be too much for Killua.
By the time Akame vs Killua was a DBX the crew did not know Akame was multi-continent by defeating Esdeath.
Then it is assuming Star is planet or universal only with specific spells and nothing else.
But we know what Death Battle buys: If she can perform a spell which is planet busting, she is planet level. If she can perform a spell which is universe busting, she is universe level.
Remember back when Esdeath is multi-continent level with Ice Storm: Commander-in-chief.
More importantly, as this may greater affect the verdict: any clips for the shrinking process of the universe itself in the Omnitraxus Prime feat?
Also, any MFTL+ speed? Like how long does Omnitraxus Prime shoot a spell to hit how far an object to make the universe shrink? Any other feats?
Star Butterfly herself is lightning dodging and in some cases light dodging (under calculation and evaluation) she can somehow scale above Marco who hit
Hekapoo who "can run across the circumference of a planet in approximately 4 seconds" (needs a clip).
