Surge arrived soon after and shocked Corroder with lightning, but Corroder blasted him with acid and sent a pillar falling on top of him and Bulk, but Furno merged and attacked Corroder. During their fight, both noticed a hero ship heading towards the site, to which Furno asked if Corroder could take on ten heroes at once.
