2025 Topps Garbage Pail Kids InterGOOlactic Mayhem Checklist

Six weekly waves of sci-fi spoofs from Topps.com, collected here as one 60-card InterGOOlactic Mayhem set

2025 Garbage Pail Kids InterGOOlactic Mayhem is a Topps.com print-on-demand release sold as six weekly sets from 29 May to 10 July 2025. Each weekly set held ten base cards and one wrapper card. This page lists all 60 base cards, 1A-30B, as one continuous set: wave 1 is 1A-5B, wave 2 6A-10B, wave 3 11A-15B, wave 4 16A-20B, wave 5 21A-25B and wave 6 26A-30B. It is a different product from the 2023 Garbage Pail Kids Series 2: InterGOOlactic Mayhem retail set; here 1A is Half Hailey.

What's in the checklist

• Base: 60 cards, 30 subjects with A and B names, named as printed on Topps's wave pages
• Parallels: none listed for the base cards
• Inserts: each set held a wrapper card or a Gold Foil Wrapper /25, with five wrapper subjects a week. Topps publishes no wrapper names or numbers, so no wrapper rows are shown
• Variations and autographs: none listed; no autograph roster is established

Notable subjects

Half Hailey (1A), Stuck SETH (5A), Critical CROW (11A), Repo STAN (19A), Space GORDON (21A) and Game Over MANNY (30B), one from each of the six waves' sci-fi spoofs.

Snapshot

This is a source-limited, dated snapshot as of 9 October 2026 based on Topps's six wave pages. It is not a complete master checklist. Topps's per-wave print runs count sets made, not serial numbers. Weekly sale windows are store dates; no release date is set.

Grading considerations

Identify each card by year, set name, number and suffix: the A and B names share a number, and the 2023 retail set reuses the InterGOOlactic Mayhem name with different cards. Match the printed name, since alternate names on similar art are different cards. Check corners, edges and centering on both sides, and inspect the surface under angled light for print lines, scratches and dents. A Gold Foil Wrapper should match its /25 serial to the gold finish.
