3. Iron Mandrill
Marvel Apes was a four-issue miniseries which was pitched to Marvel after the mild success of the Marvel Zombies. Iron Mandril is a part of Ape-Vengers. Marty Gibbon once joined the Spider-Monkey and the Ape-Vengers to take down Doctor Ooktapus. The Iron Mandril suit is pretty impressing and looks like a mechanical ape.
