Lantzblades put that actually to metagame, as well as any other BS he smuggled in after Elf approved his barebones sheet.
No, he didn't. His sheet might have been unclear on the details, but Satoshi's backstory was written (at least broadly) a
long time before this RP happened. And, even if he had added it as an extra thing after the fact, the sheet was written months before Gray showed up and entered the Symbiote into the game, so it would
still not be meta-gaming in this context.
Plus, as I already said, he is not the only one with knowledge from comics, anime etc. Several others (Forest included) knew who the Hulk was. It's
possible that some of my characters might have heard of the Symbiote (albeit unlikely), and they certainly would have heard of any characters who are popular in Japan.
Whether or not Marvel exists in the Nasuverse canonically is not clear, but Satoshi's knowledge of comic book characters was mentioned well before you ever showed up (it's in his sheet, even), so it's not meta-gaming. Further, not only did several other people recognise the Hulk, but a whole bunch of characters (including Satoshi) remarked on the presense of a Pokemon, so there is definite precident for knowing about the stories of other characters.
Unless he's specifically stated to be an avid Spiderman reader, it's metagaming.
No, sorry, that is just bullshit. If a character sheet had to mention every single thing a character had ever done in that much detail, it would be about 20 pages long. He is stated to read comic books both in the sheet and also previously in the RP, and reading comic books is not something you would expect a character sheet to logically focus on, so he is
fully entitled to flesh that out more.
Just because my sheet doesn't say that my character doesn't like eating a particular food, it doesn't mean that I'd be meta-gaming if I included that information later in the RP, because it's not important enough to put in the original sheet.
If your logic held, then every character would be extremely ignorant and utterly flat characters who couldn't do or know anything that wasn't explicitly stated in their sheet and who were not able to have any emotional reactions not mentioned in their sheet, and that would make for an
extremely dull RP.
