I remember reading a comic back in middle school, so both the time period and what I remember of the art date it as mid 2000s. It starts off with him eating at a diner, then some basic plot stuff happens, when he finds a hatch down into a secret bunker filled with kryptonians. Also I think his das is there, but as a hologram. A lot of the kryptonians call him a baby and are taller than he is, and he can’t fly in the bunker city. They also don’t let him leave till the last issue.
I don’t know if it was a dedicated mini series or what but it was probably about 6 issues long, can anyone help?
