Know Your Giant Robots!

Hey folks, here's a little game to celebrate Ani-Pock's birthday week.
Can you name this giant robot? I'll start with an easy one.
This giant Robot wasn't even completed until halfway through the series, and although this show was famous for creating the "GINAX bounce" the mechs for which this late eighties anime is named weren't the one offering this fanservice.

XD
It will be fun to see what you guys answer! Good luck!
It won't be so easy next time.
