Fenrir [1st Edition] #IOC-020 collector guide

About Fenrir

Fenrir is an Effect Monster, printed as IOC-020 in Invasion of Chaos (2004) as a Common. It is a Level 4 WATER Beast monster with 1,400 ATK and 1,200 DEF. Invasion of Chaos, released in 2004, brought Black Luster Soldier - Envoy of the Beginning, Chaos Emperor Dragon - Envoy of the End and Dark Magician of Chaos. The Envoys went on to dominate competitive play, which makes it one of the most important sets of the early game. Ungraded, this printing ranks 90th of the 224 Invasion of Chaos cards we track. The top card is Black Luster Soldier - Envoy of the Beginning at €143.91.

Character and collecting appeal

Beasts are one of the classic monster Types of the original series. Its text is about Special Summoning and destroying cards. It cannot be Normal Summoned, so it has to be brought out by its own conditions.

Version and identification

This guide covers the 1st Edition printing. The words "1st Edition" are printed below the artwork on the left; copies without them are the Unlimited printing and usually sell for less. Check the code printed below the artwork on the right: it should read IOC-020. The code IOC-020, without a language letter, marks the original North American printing. European English copies have an E in the code, such as IOC-E020, and are priced separately. It is the Common version. Commons have a plain name and no foil. Invasion of Chaos has one other printing of Fenrir: IOC-020 (€0.43). Each has its own price, so match the code, edition and rarity exactly.

Price history

Today an ungraded copy of this printing sells for about €1.25, a PSA 9 for €7.13 and a PSA 10 for €69.56. Our monthly prices for it go back to October 2021. Over the last 12 months ungraded copies are down 32%, and up 67% in the last month. Its highest monthly ungraded value was €1.85 in June 2025, 32% above today. 1st Edition copies sell for about 2.9× the Unlimited printing (€1.25 against €0.43).

Grading and population

A PSA 10 sells for 55.6× the ungraded price and 9.8× a PSA 9. That gap is big enough that grading a sharp, well-centred copy can pay for itself. On cards from the early 2000s, the dark brown backs show every scuff and white edge, so top grades are scarce.

Investment potential

In its favour: it comes from the 1st Edition run of an early English set, which will never be printed again; an active market (26 recent completed sales), so it is easy to sell. Against it: falling prices, down 32% in a year. Past prices do not guarantee future ones. This is not financial advice.

Before you buy

Expect to pay around €1.25 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €7.13. Ask the seller to show the code IOC-020, the "1st Edition" text and the Common finish clearly in the photos, as listing titles often mix up printings. Cards from 2004 often show white wear on the back edges and corners, so ask for photos of the back before you buy.
