Ok so this is bothering me,

DEFEND NEW KRYPTON MY WAY: Adjacent friendly characters and other friendly characters that possess the Phantom Zone keyword modify their attack values by +1.

An arguement happened between two of my players. Is zod adjacent to himself? The one player cited the thing's yer ever lovin pa

YER EVER-LOVIN' PAL: At the beginning of your turn, if the Thing is adjacent to one or more friendly characters that have one or more action tokens, roll a d6. On a result of 5 or 6, you can remove an action token from one adjacent friendly character, or two adjacent friendly characters if they and the Thing all possess a single common keyword

Was there an errata to the thing because I remember a while back the thing was considered adjacent to himself.

No. See the bold part below from the 2011 Rulebook, pg 5:

No, characters are not adjacent to themselves. And Thing was never considered adjacent to himself, the errata that he received added the word "adjacent" so that he could only remove tokens from adjacent characters, not himself or characters across the map.

Mucho appreciato mate.

But Zod possesses the Phantom Zone keyword so he would get the +1 to his attack irregardless.

Nope, his trait specifies other friendly characters with Phantom Zone.
