I'm goona build Big O outta lego's

Yeah I have a lot of black lego's and though that I might be able to biuld a 1/160 scale model of our fav gaint robot.
But my problem is I don't think I'd do him justice so I need help coming up with a design, got any ideas.
All suggestions welcome.

I have no idea how you'd pull that off, but it sounds like fun!

Start with the torso and head first.

I have a vague idea how you might make the pistons (those ones with holes for wheels plus like gray wheels...or something) but the body will give you the toughest time.

I tried to do this but it just ended up as a generic megadeus. The head was pretty cool though, and it could move, had a retractable flamethrower arm, and it could "lay down"/transform kinda like how Big O rides the Groundhog.

I have pictures but I can't find them.

I'd recommend using Technic type of pieces over normal bricks.

It'd look worse, but it'd be able to move and such better, probably.

In kinda meant I need help designing. but so far I got part of the arm and body done a can't get the head.

So please help me with a design.
