Missed most of it, but I'm okay with it so far. Lion-O looks less creepy that the old man-boy (the whole concept of a little boy in that giant muscle cat weirded me out even as a kid) but I'm not sure I really like his look yet. The rest look fine (not keen on Panthro looking like Jet from Cowboy Bebop, but if he hasn't been seen yet, I won't judge).

Tygra certainly wasn't Lion-O's brother (different species!), he was the eldest and scientist, but definitely next in line for leadership.
