I thought Secret History of the Foot Clan # 1 was fantastic, although the second I saw the color of the witch's potion at work on Tatsuo's "foot" I knew its origin. Plus Kitsune morphing from woman to fox set off some obvious bells and whistles. But in a good way - the kind of science v. mysticism paradox that has been building, including the feud between Foot Clan and Dimension X as well as Leo and Donny is so important to making this series work thematically (Raph's thematics cover the whole urban street aspect, Mikey's just a cool dude although I'm sure his hidden themes will rise soon.)
More importantly, I didn't think it was coincidence that the Foot's founder shares a common name-basis with Tatsu from the movies. (PS, there's a guy I'd like to have turn up. They need to play up a little more of the old "Foot recruits street punks" side of things. Preferably by having a friend of Michelangelo fall in with that crowd). Sure, Karai basically serves that function, but the Foot can always use a "Badass Drill Sergeant" type and he's the guy.
Another cool thing is this being a further indication of April's sort of "renaissance woman" status. Overall, as a scientist she grew suspicious and became a snoop. In the original books obviously she was the lab assistant, but in later media a reporter. Her snooping there, and here could lead to that career in the future. But anyway, here she's in an archaeology class, which fits with the other side of April - her love of antiques, owning the Antique Shop from her dad, and in the '05 TMNT movie, she was even importing priceless relics. So we're getting every side of April, and her being a college student is kind of a convenient and logical way of granting her access to these interests that thematically help the Turtles.
I'll take the ragged, stylized designs on the bandanas in this mini but I don't want to see it crop up in the regular books. Not that I expect it will. So far I'm liking these links that are being drawn.
My main beef? Honestly it's Casey's hair. Which isn't limited to the mini. Grow it. Casey looks un-Casey without a mane. I know the original depiction had messy, short hair, the 80s cartoon did, the toy did and the recent TMNT flick did, but Casey just needs long hair, man, and denim and cut-off sleeves and fingerless gloves. Elias Koteas swagger.
