Let’s try this again because Supernova is WAY too powerful

Xander can only have 3 weapons at most. Those three are as followed
•Murasama + Ankh shield
•True Paladin’s Warhammer of Power
•Draconian Rage

saike at his current level probably couldn't beat Xander, but he would put up a fight, and him and astra are about the same

Since this is a Free for all and Xander is limited to three weapons, Saike could play the long game, and wait until the both of them are weakened enough

I mean it matters how the fight pans out

Hmm

Saike was able to temporarily disable Astra's nanotech regeneration, so she'd probably get taken down.

And with what anon said xander would win

If it were just saike though she'd have way more of a chance
