BTC vs Embrace

Winner - Embrace

Pikachu vs Vulk - Winner: Pikachu. Pikachu’s physicals are pretty questionable compared to Vulk’s, but his lightning was portrayed to be strong enough that Vulk likely couldn’t take more than a few blasts at best. There was a whole lot of shaky scaling for Pikachu that BTC poked holes in but the lightning itself and Vulk’s relative lack of electric resistance gives Embrace the win

Greninja vs Sanguinus - Winner: Greninja. This matchup was close, but Embrace manages to strongly argue Greninja’s piercing shuriken, giving him an advantage at both range and close combat, along with establishing him as physically stronger.

Luke Cage vs Roboute Guilliman
Robodude is unfortunately out of tier as argued
Luke Cage is pretty similar to Thing stats wise and is argued as getting one-shot by Guillimna, which obviously translates to him one-shotting Thing as well
