*NOTE* Before you try to "correct" any of the information I've listed on his sheet, please be aware that all the listed information is canon to the Jeff in "The Seer" universe. Facts and data regarding Jeffs from other universes are irrelevant, seeing as this version of Jeff is my own personal headcanon.
I figured I'd start making some reference sheets with all the "canon" info regarding the characters in the "Seer" universe. Hopefully this answers some questions. I'll be making sheets for various other characters as well. c:
