#m 11

During an operation in Cuba in the 50s, Atlas ran into Marvel's Forrest Gump - Wolverine. Their goals aligned and they worked together for a time, but Logan refused a debriefing and detonated the bomb he strapped to M-11, my favourite sentient automaton.

In the 60s, the X-Men enlisted the help of Ken Hale - Gorilla Man - to find Chuck after he got himself lost in a cursed temple.

Much later, during Norman Osborne's Dark Reign, Atlas were attacked by The Avengers. They had just made peace when...

M-11 recognised Logan's voice as 'that asshole that blew me up in the 50s.' He blew his arm off.

About a month later, their teammate Venus had been kidnapped by the real Venus/Aphrodite and they were having difficulty finding her. They decided to borrow Cerebro without asking..

... and got a face full of X-Men.

They fought a fighting retreat with Cerebro and escaped to their city beneath San Francisco, but got X-Men'd again.

Though they weren't ready for Mr Lao, Jimmy's consigliere.

In a historic first, Namor de-escalated a conflict. Only because his cousin Namora is an Agent of Atlas... and Atlas is allies with Atlantis.
