#4 THE BUG

It's a giant bug ship. It'll creep out your wife. Get it, stick it in your aquarium, and enjoy.

From the DC Wikia:
"The Bug was built by research scientist Ted Kord, in the time when he was still president of the Kord Omniversal Research and Development Inc. It was originally constructed from failed experiments and old parts of automobiles and later improved with Ted's new inventions.

Before retiring from the super-heroic life, Ted built two more versions called Mark I and Mark II. The Mark II was destroyed during Countdown to Final Crisis, while the Mark I was altered by Checkmate to cover up Ted Kord's death."
