megablocks and kre-o were the north american 'legal' knockoffs.
former has license to pokemon, halo, star trek and others, while kre-o had transformers and gi-joe.
i have the kreo gi joe H.I.S.S. tank, a few transformers that got dumped in the box & a halo mantis mech.
lots of china fake brands. i only know my world as i got a lot of minecraft knockoffs until my youngest is like naw i ain't playing with this and separates lego from fake boxes
