You can watch the last glorious Adam West cameo in this unaired episode of 'Powerless'

Adam West may have passed away last week, but memorials to the iconic Batman actor continue to pour in.

Along with the flood of tributes from his peers and admirers on social media and the touching Bat-signal display on the Las Angeles City Hall building, West's last media appearances are making the internet rounds.

The actor, who died at 88 from complications from leukemia, kept busy up until the end, as he was almost as famous for his career's second act poking fun of and referencing the persona he created with his most famous role -- but his final TV appearance, a cameo on NBC's Powerless, never aired after the show was cancelled before it finished its first season.

Now, the network has put the full episode, "Win, Luthor, Draw," up on YouTube in memoriam, giving everyone one last chance to see West do what he did best.

It was a fitting last bow for the actor -- the DC show depicted a world filled with superheroes like Batman and Superman, with much of its action taking place in the R&D department of Wayne Security, a subsidiary of Wayne Industries. That's Wayne as in Bruce Wayne, Batman's billionaire alter-ego.

West popped in as Dean West, Chairman of Wayne Enterprises. The quick appearance is chock full of callbacks to his Batman days and his self-deprecating second act, and in a meta-moment West (the character) calls it a "bit of a gratuitous cameo."

The episode will be only be available for a limited time, and with Powerless off the air, you won't be catching it anytime soon at the same Bat-time on the same Bat-channel. Give it a watch now, and pay your respects to the actor who was, for many, the best Batman of them all.
