Guys... this seems to be a mess.
The bio as it stands seems to cover only the period between Infinite Crisis and Flashpoint as well as sticking to "New Earth" continuity.
The appearance list covers New Earth, Earth-Prime, and pre-Zero Hour continuities.
As near as I can tell, the character used in Action Comics, Adventure Comics, Justice League of America Vol, L.E.G.I.O.N., Superman, "Last Stand of New Krypton", and Titans was native to "New Earth" and wound up joining the pre-Zero Hour LSH (Adventure Comics Vol 2 11).
Should we remove the New Earth material from here and appended it to Lar Gand (Pre-Zero Hour) or a new page and reassign the appearances?
This does create one hell of a mess since the pre-Zero Hour character does not fit the New Earth history and there are essentialy two runs at a "New Earth" native Lar Gand - this one and Lar Gand (Post-Zero Hour).
