"Whizzer."

I forget how exactly Peter Parker climbs walls now, if it's weird little hairs or static electricity or.something else. But Spider-Man 2099 had little claws from the get-go: they are sharp as hell and pretty effective weapons, even if Miguel is understandably squeamish about slicing anyone up like that. That said, I can't remember offhand what, if anything, the arm spikes do or are for. 

We keep seeing the Elders refer to each other by name rather than title, which is a weird callback to old Official Handbook of the Marvel Universe issues. I don't think Ego had another name, but he wouldn't have been part of another race at some point like the other guys. I thought the Champion's real name was 'Tycho' and not Tryco Slatterus, though. The Collector, Taneleer Tivan, does have a daughter, Carina: I was thinking of her since she's an NPC in Contest of Champions, but she was Korvac's girlfriend back in the day!
