here is my Behemoth!

looks like a lunatic carrying a chopper.

and my bronze Pit Lord.
leveled it up to Level 10 with the help of Captain Peace and Valkyrie.
now i am crossbreeding it with a Zombie.
either get a Grim Reapress or a Baron Lundi.
Grim Reapress pls.
she looks so badass!

and my Bronze Enforcer!
got it by crossbreeding a Nordic Knightmare and a Robot i believe.

as for Martian Marauder....
nope i haven't get it yet.
i have tried like at least 5 times.
but all i got were Bounty Bugs.
which i sold for 42k credits per Bug.
well, better luck next time!
