Technarchy Siredam vs BRB

Can BRB defeat a fully grown Technarch Siredam? This is the same Siredam found in Annihilation: Conquest. And current BRB.

The Siredam should outmatch him. The one we saw was significantly stronger than Nova.

BRB cannot handle a full-grown Siredam. Too much damn firepower and regeneration capability.

BRB is a level higher than Nova, though. With planet busting power. Siredams present a very large (and easy to hit) target.

Can BRB get some wins? Or is he completely pwnd in this scenario?

Not much higher, I'd be amazed if Nova couldn't planet bust if he really wanted to.
