i just replaced the old batteries to make sure, he still works (the only part i didn't replace were the old clock batteries as they are those round ones and i didn't have any of them). the only problem with him is that sometimes his eyelids stay closed but they'll reopen when he talks again. he's also a little dirty due to dust and i'm too afraid to wash him.

if you'd like to see more pictures of him i can take more.

as for the season 4 figures, i have most of the bad spirits, zephyrmon, Agunimon, and others that i can't remember off the top of my head. i have neemon too. i don't think i have any of the Lobomon line.

as for the rest that you listed i have hawkmon, baihumon, antylamon (i think)and garudamon (i think)
