Sabertooth Asked Galactus for a Power Boost

When the Exiles hop to another reality (on Earth-552), they find one in which Galactus restored worlds instead of consuming them and the Silver Surfer is absolutely evil. When the Surfer tries to force Galactus to restore life to his homeworld of Zenn-La, Galactus refuses and a fight erupts between the two. The Exiles moved in to provide aid, but they were no match for the Silver Surfer.

Sabretooth asked Galactus to give him a power boost, which he quickly does. Sabretooth then calls himself "Silver Sabretooth" despite being golden in color, and puts it to the Surfer. He even offers to return the Power Cosmic to Galactus, who humbly accepts, and the Exiles go on about their business. Sabretooth's brief stint as a herald is enough to land him mid-list in the rankings at number 10.
