That’s not Vader’s Mom, it’s Sith’s Mom. This is Vader’s Mom:

Of course all her children loved her. Would they be allowed to live if they didn’t?

Ready for the All-you-can-eat Early Bird buffet at Red Lobster.

I keep forgetting. Mother’s Day was this past Sunday where I live. Europe has different customs.

Darth, I am your mother! Why don’t you ever call?

The cosmetic surgeon / vet didn’t want lady to lick herself while the implants were healing.

She could communicate with him through the Force.

I came in for a routine cleaning….and now he tells me I need a root canal and crown. It better be a gold crown, silver is just so gauche!

Comforting her pet snake.

The money was always good when she played the bishop’s palace, but Mary did not look forward to starting her pole dance in a full habit.

Best outfit at the Met’s “Heavenly Bodies: Fashion and the Catholic Imagination” gala.

Nope. Even in the Disneyverse his revenge for her death was one more giant step Anakin took to becoming Vader.

She looks like she ate my wife’s patented “Mother’s Day Bean Dip Surprise”

The solution to great grandma’s drooling problem.

At the “Death Star Assisted Living Facility” dining room, Ma Vader’s clumsy spoon-handling demanded that the attendant always tucked her napkin into her collar…

Receiving the medal for mother of the year still did not please Mother Vader.

Agatha sat away in her corner, to all observers completely placid and without bother. Little did they know she was wearing headphones under her habit and listening to death metal.

Is this too revealing?

Again, a larger strip image is shown by clicking the image in Mr. Melcher’s A PRICELESS MOTHER’S DAY CLASSIC (May 10, 2018) blog entry, accessible by the Check out the blog! box after the last comment. This was the MASTERPIECE #554 May 7, 2011, entry (predates the strip at GC; hasn’t run here before).

“Burn the witch!”

“Yes, I am your Airbnb hostess.”

sister Hellene is going to sit there till they change the convent’s habit, god it’s hot.

Or, it could be Mama Palpatine…
