The Super Giant-Form is considerably larger than the previous Great Namekian transformation. When Piccolo used this against Goku, the World Tournament announcer said he was as big as a mountain (in the manga) or volcano (in the anime). However, Goku takes advantage of Piccolo's gargantuan size in order to retrieve Kami, causing him to realize the flaws of the form and thus return to his base form.
Main article: Dark Evolution
In the Dark Empire Saga of Dragon Ball Heroes, after merging with the Six-Star Dark Dragon Ball, Slug is forced to undergo a dark evolution due to Towa. Lord Slug takes on the Dark Giant version of the Super Giant form, gaining a dark energy from his head and back, and merging with the Earth itself.

In Super Dragon Ball Heroes: World Mission Chapter 2, Side Story: "Kagyu's Adventure", on Earth during the period before the Tournament of Power, Xeno Lord Slug (Super Giant) is fought as Giant Boss in the Boss Mission "The Demon God Makes an Entrance!" who can only be defeated if Kagyu manages to defeat Demon God Salsa, Villainous Mode, Xeno Angila, Villainous Mode Xeno Wings, and Villainous Mode Xeno Medamatcha first which allows Kagyu to weaken Xeno Lord Slug (Super Giant) with Penetrate!. Afterwards, Kagyu distracts Salsa giving Piccolo (who's fusion with Kami and Nail had been undone due to an anomaly) an opening to finish off the weakened Xeno Lord Slug (Super Giant) with a Ki Blast, causing Salsa to flee which resolves the anomaly allowing Piccolo to fuse with Kami and Nail once more.
